Abstract
PURPOSE To develop a novel adaptation of the Whitaker test for assessing the surgical effects of ileal ureter replacement (IUR), and to evaluate its feasibility and effect in the postoperative evaluation. PATIENTS AND METHODS From November 2021 to September 2023, patients undergoing the modified Whitaker test following IUR were prospectively enrolled. The relative pressure was defined as the pelvis pressure minus the bladder pressure. Successful nephrostomy removal was defined as absence of symptoms and improved or stable hydronephrosis. RESULTS The 51 ureters from 39 patients underwent the modified Whitaker test after IUR. The modified Whitaker test was performed successfully on all patients without any reported discomfort. The relative pressure of 47 ureters kept steady (< 15 cmH2O) throughout the examination with well ileal ureter peristalsis and was classified into type I. The relative pressure of 2 ureters increased with perfusion reaching a range of 15-22 cmH2O, with well ileal ureteral peristalsis observed (type II). The relative pressure of 2 ureters increased along with perfusion, with weakening of ileal ureter peristalsis or a leakage of contrast medium, and the relative pressure surpassed 22 cmH2O (type III). Nephrostomy tubes were promptly removed for type I and type II ureters, while removal for type III ureters occurred after a 2-month period. None of the 39 patients required additional interventions for recurrent obstruction. CONCLUSION The modified Whitaker test was a safe and effective approach for the evaluation of surgical effects of IUR, offering additional evidence to assess the safety of nephrostomy tube removal.

Abstract
OBJECTIVE To assess the augmented anastomotic ureteral reconstruction using buccal mucosal graft based on omental flap for managing ureteral stricture. SUBJECTS AND METHODS This prospective cohort study was conducted on 13 patients with ureteric strictures of different lengths secondary to Bilhalziasis, iatrogenic (post endoscopy) and post inflammatory etiology in upper and mid ureteral segments were treated with buccal mucosal patch grafts and The graft is fixed to the undersurface or the posterior surface of the omentum before doing graft anastomosis to the ureteral walls as to ensure the process of graft take sticky to the principles of tissue transfer. All patients were subjected to full history taking, clinical examination for assessment of pain, lower or upper urinary track symptoms and laboratory investigation (complete blood count, CRP, liver function test and kidney function test (serum urea and creatinine). RESULTS The mean operative time was 148.85 min and mean hospital stay was 3 days. Mean blood loss was ranged from 20 to 210 ml and Stent was removed after 8-12 weeks. The mean follow up was 13 months, all patients had a non-obstructive RI value <0.7 with a non-obstructed drainage pattern on the diuretic renogram except one patient who had severe postoperative UTI necessitating nephrostomy tube insertion his drainage curve was plateau. CONCLUSION BMG ureteroplasty is a valuable option for a carefully selected patient. The fixation of the graft on the back surface of the omentum allows for better anatomical reconstruction without any twisting to the omental pedicle.

Abstract
Objective To describe and evaluate the technique using bilateral Boari flap ureteroneocystostomy (BBFUNC) for bilateral mid-lower ureteral strictures. Methods We retrospectively reviewed five patients who underwent minimally invasive BBFUNC in our institution (Union Hospital, Wuhan, China) between July 2019 and December 2021. The bilateral ureters were mobilized and transected above the stenotic segments. The bladder was isolated and incised longitudinally from the middle of the anterior wall. Then, an inverted U-shaped bladder flap was created on both sides, fixed onto the psoas tendon, and anastomosed to the ipsilateral distal normal ureter. Following double-J stenting, the Boari flaps were tubularized, and the bladder was closed with continuous sutures. The patients' perioperative data and follow-up outcomes were collected, and a descriptive statistical analysis was performed. Results No case converted to open surgery, and no intraoperative complication occurred. The median surgical time was 230 (range 203-294) min. The median length of the bladder flaps was 6.2 (range 4.3-10.0) cm on the left and 5.5 (range 4.7-10.5) cm on the right side. All patients had not developed recurrent ureteral stenosis during the median follow-up time of 17 (range 16-45) months and had a normal maximum flow rate after surgery. The median post-void residual was 7 (range 0-19) mL. The maximal bladder capacity was decreased in one (20%) patient. Conclusion The present study demonstrates that minimally invasive BBFUNC is feasible and safe in treating bilateral mid-lower ureteral strictures, and the impact on lower urinary tract function is limited.

Abstract
PURPOSE To present the experience of ileal ureter with ileocystoplasty (IUC), and compare the outcomes of IUC in minimally invasive procedures to open procedures. PATIENTS AND METHODS From December 2017 to April 2023, twenty patients underwent IUC in open or minimally invasive (including laparoscopic and robotic) procedures. The baseline characteristics, perioperative data and follow-up outcomes were collected. Success was defined as relief of clinical symptoms, stable postoperative serum creatine and absence of radiographic obstruction. The perioperative and follow-up outcomes of open procedures and minimally invasive procedures were compared. RESULTS The etiology included pelvic irradiation (14/20), urinary tuberculosis (3/20) and surgical injury (3/20). Bilateral ureter strictures were repaired in 15 cases. The surgeries conducted consisted of open procedures in 9 patients and minimally invasive procedures in 11 patients. Compared to open procedures, minimally invasive surgeries had less median estimated blood loss (EBL) (100 ml vs. 300 min, p = 0.010) and shorter postoperative hospitalization (27 d vs. 13 d, p = 0.004). Two patients in the open group experienced grade 3 complications (sigmoid fistula and acute cholecystitis in one patient, and pulmonary embolism in another patient). Over a median follow-up period of 20.1 months, the median bladder functional capacity was 300 ml, with a 100% success rate of IUC. CONCLUSION IUC is feasible in both open and minimally invasive procedures, with acceptable complications and a high success rate. Minimally invasive procedures can have less EBL and shorter postoperative hospitalization than open procedure. However, prospective studies with larger groups and longer follow-up are needed.

Abstract
OBJECTIVE To present long-term results of our laparoscopic intracorporeal ileal ureter replacement (LIUR) cohort, including more complex cases of laparoscopic ileocalycostomy. MATERIAL AND METHODS We collected records of patients undergoing LIUR. Follow-up included a chemical profile and urine cultures. Imaging consisted of renal ultrasonography, excretory urography, cystography, and computer tomographic or magnetic resonance urography. RESULTS One hundred and two patients were included. Stricture location was left (46.1%), right (39.2%), or bilateral (14.7%). No open conversion was performed. Seventy-four patients (72.5%) underwent a total ureteral unit removal. The mean operative time was 289.4 (120 - 680) minutes. The estimated blood loss was 185.2 (10-400) mL. Three patients had intraoperative complications, and fifteen had early postoperative complications. The mean postoperative hospital stay was 12.2 (7-35) days. The mean follow-up duration period was 37.7 (12-162) months. Most patients' follow-up was uneventful (88%), and seven patients presented with Grade 2 late complications. CONCLUSIONS Intracorporeal laparoscopic ileal ureteral replacement in cases of extensive ureteral lesions offers optimal long-term outcomes and a low complication rate. Ileocalycostomy constitutes a viable option in the small group of patients with long proximal ureteral strictures and intrarenal pelvis.

Abstract
OBJECTIVE To examine long-term ileal ureter replacement results at over 32 years at our institution. Long segment or proximal ureteral strictures pose a challenging reconstructive problem. Ureteroureterostomy, psoas hitch, Boari flap, buccal ureteroplasty, and autotransplantation are common reconstructive techniques. We show that ileal ureter remains a lasting option. METHODS We performed a retrospective review of patients undergoing open ileal ureter creation from 1989-2021. Patient demographics, operative history, and complications were examined. All patients were followed for changes in renal function. Demographic data were analyzed and Cox proportional hazard models were performed. RESULTS One hundred and fifty-eight patients were identified with median follow-up time of 40 months. Eighty-one percent had a unilateral ileal ureter creation. Fifty percent were female, median age was 53.3. Twenty-seven percent of patients had radiation-induced strictures. Preoperatively, 56.3% of patients were chronic kidney disease stage 1-2 and 43.7% were stage 3-5. Post-operatively, 54% were stage 1-2 and 46% were stage 3-5. Cox proportional hazard models demonstrated no significant correlation between worsening renal function and stricture cause, bilateral repair, complications, or sex (biologically male or female). Seventy-seven percent had no 30-day complications. Clavien complications included grade 1 (18), grade 2 (4), grade 3 (9), and grade 4 (5). Long-term complications included worsening renal function (3%), incisional hernia (8.2%), and small bowel obstruction (6.9%). Five (3.1%) patients ultimately required dialysis and 5 (3.1%) patients developed metabolic acidosis. CONCLUSION Ileal ureteral reconstruction is often a last resort for patients with complex ureteral injuries. Clinicians can be reassured by our long-term data that ileal ureteral creation is a safe treatment with good preservation of renal function and low risk of hemodialysis and metabolic acidosis.

Abstract
PURPOSE Successful treatment options for ureteral strictures are limited. Surgical options such as ileal interposition and kidney autotransplantation are difficult and associated with morbidity and complications. Techniques such as Boari flap and psoas hitch are limited to distal strictures. Only limited case studies on the success of open buccal mucosa graft (BMG) ureteroplasty exist to this date. The purpose of this study was to evaluate the success of open BMG ureteroplasty without omental wrap. METHODS In this single-center retrospective study between July 2020 and January 2023, we included 14 consecutive patients with ureteric strictures who were treated with open BMG ureteroplasty without omental wrap. The primary outcome was the success of open BMG ureteroplasty. Further endpoints were complications and hospital readmission. Outcome variables were assessed by clinical examination, kidney sonography, and patient anamnesis. RESULTS Out of 14 patients, 13 were stricture and ectasia-free without a double-J stent at a median follow-up of 15 months (success rate 93%). No complications were observed at the donor site, and the complication rate overall was low with 3 out of 14 patients (21%) having mild-to-medium complications. CONCLUSIONS Open BMG ureteroplasty without omental wrap is a successful and feasible technique for ureteric stricture repair.

Abstract
BACKGROUND The aim of this study was to explore the feasibility of ileal ureter replacement and ileocystoplasty for the treatment of bilateral long-segment ureteral strictures combined with bladder contracture. METHODS A retrospective review of clinical data from seven patients who underwent bilateral Ileal Ureter Replacement and ileocystoplasty from April 2019 to February 2023 was conducted. The surgeries were performed using open, laparoscopic, and robot-assisted laparoscopic approaches. Baseline characteristics, perioperative, and mid-term results of the patients were collected. Follow-up period of 3-28 months. A detailed description of the technique was reported. RESULTS The mean age of the patients was 52.86±6.06 years. The average duration of surgery was 365±28.54 minutes, and the estimated intraoperative blood loss was 357.14±184.06 mL. The mean length of harvested ileum was 37.86±8.40 cm. The preoperative serum creatinine level was 88.02±18.05 μmol/L, postoperative day 1 creatinine level was 90.7±12.93μmol/L, postoperative 3-month creatinine level was 93.77±33.34 μmol/L, and the mean creatinine level at the last follow-up was 94.89±27.89μmol/L. The postoperative bladder capacity was 249.43±32.50 mL on average. The average length of hospital stay was 26.57±15.46 days. No complications of Clavien-Dindo grade 3 or higher were observed. During the follow-up period, no patients experienced deterioration of renal function after surgery. CONCLUSIONS Bilateral ileal ureter replacement and ileocystoplasty are effective surgical technique for the treatment of bilateral long-segment ureteral strictures combined with bladder contracture caused by radiation therapy.

Ileal Interposition for Ureteral Reconstruction Following Treatment for Abdominopelvic Malignancy: Complications and Outcomes From a Comprehensive Cancer Center. Urology 2024; 183:215-220. [PMID: 37802194 DOI: 10.1016/j.urology.2023.09.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 09/18/2023] [Accepted: 09/26/2023] [Indexed: 10/08/2023]
Abstract
OBJECTIVE To characterize the outcomes of ileal interposition for the management of ureteral obstruction from tumor and ureteral stricture following treatment for abdominopelvic malignancy. MATERIALS AND METHODS A retrospective database analysis was performed for all cases of ileal interposition performed by 5 surgeons from January 2013 to December 2020. Patients were ≥18 years of age and included if undergoing ileal interposition in either the primary setting of a surgical procedure for tumor extirpation or in the delayed setting. RESULTS In total, 23 patients who underwent repair of 27 ureteral units were included. The mean age was 60.2 years. Median follow-up was 21.6 months. The most common primary diagnoses were urothelial (35%), colorectal (31%), and cervical (22%) cancer. The etiologies of ureteral obstruction were malignant in 48% and ureteral stricture in 52%. Types of repairs included unilateral interposition in 13 patients, bilateral interposition in 1 patient, interposition to an ileal conduit in 3 patients, and interposition with cystoplasty in 6 patients. There was a statistically significant difference between the mean preoperative (Creatinine 1.05 mg/dL, Estimated Glomerular Filtration Rate 77 ml/min/1.73 m2) renal function and postoperative (Creatinine 1.26 mg/dL, Estimated Glomerular Filtration Rate 67 mL/min/1.73 m2) renal function at the most recent follow-up (P = .024). Eight minor (grade 1-2) and 6 major (grade ≥3) complications developed for a minor and major complication rate of 35% and 26%, respectively. CONCLUSION Ileal interposition is successfully utilized as a reconstructive technique at the time of enbloc resection involving the ureter and to address ureteral stricture in the delayed setting.

[PMID: 37076019 DOI: 10.1016/j.urology.2023.04.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 03/29/2023] [Accepted: 04/04/2023] [Indexed: 04/21/2023]
Abstract
OBJECTIVE To evaluate a subset of patients who develop strictures requiring Ileal Ureter (IU) in the setting of prior urinary diversion or augmentation (ileal conduits, neobladders, continent urinary diversions). To our knowledge, there are no prior studies on patients with IU substitution into established lower urinary tract reconstructions. METHODS A retrospective review of patients (18 years) undergoing IU creation from 1989 to 2021 was performed. A total of 160 patients were identified. In total, 19 (12%) patients had IUs into diversions. We examined demographics, stricture cause, diversion type, renal function, and postoperative complications. RESULTS Nineteen patients were identified. Sixteen were male. Mean age was 57.7(SD 17.0) years. Diversions included continent urinary reservoirs (4), neobladders (5), ileal conduits (7), and bladder augmentations with Monti channels (3). Fifteen had unilateral surgery, and 4 had bilateral "reverse 7" IU creation. Average length of stay was 7.6 days (SD 2.9). Average follow-up was 32.9 months (SD 27). Mean preoperative creatinine was 1.5 (SD 0.4); mean postoperative creatinine at most recent follow-up was 1.6 (SD 0.7). There was no significant difference between pre- and postoperative creatinine (P = .18). One patient had a ventriculoperitoneal Shunt infection resulting ventriculoperitoneal shunt externalization, 1 had Clostridium difficile infection potentially causing an entero-neobladder fistula, 2 with ileus, 1 urine leak, and 1 wound infection. None required renal replacement therapy. CONCLUSION Patients with urinary diversions and prior bowel reconstructive surgeries with subsequent ureteral strictures are a challenging cohort of patients. In properly selected patients, ureteral reconstruction with ileum is feasible and preserves renal function with minimal long-term complications.

Abstract
PURPOSE OF REVIEW To understand the indications and outcomes of renal autotransplantation, and when to consider this unique procedure for patients. RECENT FINDINGS Renal autotransplantation confers acceptably low rates of graft failure and prevents need for long-term dialysis. Renal autotransplantation remains an important management strategy in very select patients for complex renovascular disease, ureteral stricture disease, ureteral trauma, upper urinary tract urothelial carcinoma, renal cell carcinoma, and Loin-Pain Hematuria Syndrome. With advancements in minimally invasive procedures, the application of renal autotransplantation for refractory stone disease is rare but exists. Robot-assisted laparoscopic renal autotransplantation demonstrates reproducible graft success and complication rates with improved perioperative outcomes (ex. hospital length of stay) - though comparative studies are lacking. Patients would benefit from a multidisciplinary approach from renal transplant surgeons, vascular surgeons, urologists, nephrologists, dieticians, pain management providers, social workers, and psychiatrists. SUMMARY In experienced hands, renal autotransplantation is a reasonable treatment approach for complex and refractory renal vascular disease, Loin-Pain Hematuria Syndrome, ureteral strictures and trauma, upper urinary tract malignancy, and stone disease in highly select patients.

Abstract
Complex urinary tract reconstruction has significantly advanced with the increasing use of robot-assisted procedures. Robotic surgery aims to achieve the same outcomes as open surgery while minimizing morbidity by causing less blood loss, faster postoperative recovery, and reducing complications. This article shares our technique, challenges encountered, and experience of robot-assisted complex urinary tract reconstruction using intestinal segments. Between January 2020 to March 2022, 6 patients who underwent robot-assisted complex urinary tract reconstruction using intestinal segments at our centre were retrospectively reviewed. Demographic, clinical, and operative data were recorded. Patients underwent renal function tests, blood gas analysis, and radiographic imaging in the follow-up. Symptomatic and radiologic relief were the criteria for success. Out of 6 cases, three patients underwent ileal ureter replacement, two combined ileal ureter with augmentation ileo-cystoplasty and one augmentation ileo-cystoplasty alone. The mean age, estimated blood loss, length of hospital stay, and follow-up period were 32.6 years, 110 ± 13.1 mL, 7.0 ± 1.1 days, and 11.3 months, respectively. The indications for surgery were either benign ureteral stricture following lithotripsy or sequelae of genitourinary tuberculosis. No intra-operative complications were found. Clavien-Dindo grade-II and Grade-IIIa were found in three and one patient, respectively. During follow-up, none had compromised renal function or acidosis. Robot-assisted complex urinary tract reconstruction using intestinal segments is safe and offers the advantages of minimally invasive techniques. Techniques demonstrated in this article make these reconstructions feasible with good surgical and clinical outcomes.

Abstract
BACKGROUND Ureteroscopy is well-established as a primary treatment modality for urolithiasis. Ureteral avulsion, particularly complete or full-length avulsion with a resultant long segment of the ureter left attached to the ureteroscope, is a rare but devastating complication of the procedure. Management of this complication is challenging. Moreover, general consensus regarding the optimal management is undetermined. We report our experience of managing a complete ureteral avulsion case via an extended Boari flap technique with long-term results.
CASE SUMMARY A 41-year-old female patient subjected to complete ureteral avulsion caused by ureteroscopy was referred to our hospital. A modified, extended Boari flap technique was successfully performed to repair the full-length ureteral defect. Maximal mobilization of the bladder and affected kidney followed by psoas hitch and downward nephropexy maximized the probability of a tension-free anastomosis. Meticulous blood supply preservation to the flap also contributed to the success. During the 4-year study period, no complications except for a mild urinary frequency and a slightly lower maximum urinary flow rate were reported. The patient was satisfied with the surgical outcomes.
CONCLUSION The extended Boari flap procedure is a feasible and preferred technique to manage complete ureteral avulsion, particularly in emergencies.

Abstract
INTRODUCTION To describe our initial experience with ileal ureteral replacement (IUR) for the management of ureteral avulsion (UA) during ureteroscopic lithotripsy. METHODS Between September 2010 and April 2021, ten patients received ileal ureteral replacement for ureteral avulsion during ureteroscopic lithotripsy. Anterograde urography and computed tomography urography (CTU) were applied to evaluate the lesion. Follow-up was performed with magnetic resonance urography and renal ultrasound as well as clinical assessment of symptoms. We retrospectively analysed the clinical data of ten patients treated with ileal ureteral replacement for the treatment of ureteral avulsion. RESULTS Four patients underwent open ileal ureteral replacement, two underwent laparoscopic ileal ureteral replacement, and four underwent robotic-assisted ileal ureteral replacement. The mean operative time (OT) was 310 min (range 191-530). The mean estimated blood loss (EBL) was 193 mL (range 10-1000). The mean length of the ileal graft was 21 cm (range 12-25). The median postoperative hospital time was 13 days (range 7-19). All surgeries were effectively completed, and no case required open conversion in laparoscopic and robotic-assisted surgeries. There was no obvious hydronephrosis according to contrast-enhanced computed tomography 3-dimensional reconstruction images without serious complications or progressive hydronephrosis during a median follow-up duration of 51 months (range 5-131), and the success rate was 100%. CONCLUSIONS Our initial results and experience showed that ileal ureteral replacement for the management of ureteral avulsion during ureteroscopic lithotripsy is safe and feasible.

Abstract
<b><i>Introduction:</i></b> Upper tract urinary cancer recurrence (UTUCR) after radical cystectomy (RC) is outcome-limiting. Surgical recommendations on intraoperative performance of frozen section analysis (FSA) and management of positive ureteral margin (PUM) are lacking. <b><i>Methods:</i></b> 634 RC cases were identified (2010–2018). In patients with PUM, sequential ureteral resections up to a negative margin were performed. We investigated the accuracy of FSA, significance of PUM, and identified risk factors (RFs) to stratify patients for UTUCR. <b><i>Results:</i></b> FSA was performed in 355 patients, including a total of 693 ureters. FSA sensitivity was 0.93 and specificity 0.99. PUM conversion was possible in 52 (91.2%) cases. UTUCR occurred in 17 (4.8%) patients. Identified UTUCR RFs are non-muscle invasive bladder carcinoma (NMIBC) (OR 3.8, 95% confidence intervals [CI] 1.4–10.2, <i>p</i> = 0.008), multifocal bladder cancer in cystectomy specimen (OR 4.7, CI 1.1–20.8, <i>p</i> = 0.042), and recurrent NMIBC (OR 4.1, CI 1.5–10.9, <i>p</i> = 0.006). Risk-group stratification showed a six-fold increase in UTUCR risk (low-to high-risk). <b><i>Conclusion:</i></b> FSA is a sensitive and specific method to identify PUM. UTUCR occurs significantly more often in patients with recurrent, multifocal NMIBC at the time of RC. Patients can be risk stratified for UTUCR. In case of NMIBC-PUM, surgeons can safely opt for a kidney preserving strategy.

Abstract
The treatment of ureteral stricture is a challenging task, especially when multiple strictures are present. Here, we report on a 63-year-old male patient diagnosed with hydronephrosis with left ureteral strictures who was admitted to our hospital. During treatment, a left percutaneous nephrostomy tube was inserted for hydronephrosis. Antegrade and retrograde pyelography were performed simultaneously. The results suggested there were 3 segment ureteral strictures in the left ureter: 2 located in the distal ureter and 1 in the proximal ureter. The treatment choices for multiple ureteral strictures are kidney autotransplantation or an ileal ureteral replacement (IUR), which are both morbid procedures and are technically challenging. With the excellent results of lingual mucosal graft (LMG) in ureteroplasty, this patient underwent a one-stage left ureter reconstruction with combined laparoscopic LMG ureteroplasty and ureterovesical reimplantation. However, disease of the oral mucosa and a reduced bladder volume caused by radio cystitis or chemical cystitis, may limit the use of this technique. Regular postoperative antegrade pyelography and the Whitaker test showed the unimpeded drainage of the left ureter. Based on the satisfactory outcome of this patient, combined laparoscopic LMG ureteroplasty and ureterovesical reimplantation for unilateral multiple ureteral strictures is a viable option that has fewer complications.

Abstract
We present an exceptional case of a patient with complete ureteral loss. The injury of the patient’s right ureter resulted as a complication of prior ureteroscopic and laparoscopic. For the treatment of complete ureteral loss, the right kidney was removed and placed into the left iliac fossa. Revascularization of the kidney was performed by anastomosis of the renal vasculatures to the external iliac vasculature. Ureteral reconstruction was performed through a Boari bladder flap. At the six-month follow-up visit, the resistive indices of the transplanted kidney proved to be in the normal range.

Abstract
Ureteral reconstruction with autologous tissue grafts is often limited by tissue availability and donor site morbidity. This study investigates the performance of acellular, bi-layer silk fibroin (BLSF) scaffolds in a porcine model of ureteroplasty. Tubular ureteroplasty with BLSF grafts in combination with transient stenting for 8 weeks was performed in adult female, Yucatan, mini-swine (N = 5). Animals were maintained for 12 weeks post-op with imaging of neoconduits using ultrasonography and retrograde ureteropyelography carried out at 2 and 4 weeks intervals. End-point analyses of ureteral neotissues and unoperated controls included histological, immunohistochemical (IHC), histomorphometric evaluations as well as ex vivo functional assessments of contraction/relaxation. All animals survived until scheduled euthanasia and displayed mild hydronephrosis (Grades 1-2) in reconstructed collecting systems during the 8 weeks stenting period with one animal presenting with a persistent subcutaneous fistula at 2 weeks post-op. By 12 weeks of scaffold implantation, unstented neoconduits led to severe hydronephrosis (Grade 4) and stricture formation in the interior of graft sites in 80% of swine. Bulk scaffold extrusion into the distal ureter was also apparent in 60% of swine contributing to ureteral obstruction. However, histological and IHC analyses revealed the formation of innervated, vascularized neotissues with a-smooth muscle actin+ and SM22α+ smooth muscle bundles as well as uroplakin 3A+ and pan-cytokeratin + urothelium. Ex vivo contractility and relaxation responses of neotissues were similar to unoperated control segments. BLSF biomaterials represent emerging platforms for tubular ureteroplasty, however further optimization is needed to improve in vivo degradation kinetics and mitigate stricture formation.

Abstract
A SHORT INTRODUCTION Irreversible ureteral damage is a rare and challenging problem for pediatric urologists. Ileal replacement has become one of the limited surgical options for ureteral reconstruction. Only a few papers have examined the results of the ileal ureter and renal function outcomes. Furthermore, there are even fewer papers showing patients with the intestinal ureter, which is used to drain urine from a solitary kidney in early childhood. AN OBJECTIVE To perform a systematic review and analyze available cases of the long-term function of the "neoureter" and differences in the surgical approach. To present the case of a 29-year-old female with a history of ileal replacement of the ureter in a solitary kidney which was performed in this patient at the age of 14 months. STUDY DESIGN PubMed and Scopus were used to search for eligible articles. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were strictly followed. Based on the titles, abstracts, and full-text reviews, 77 articles were analyzed, of which only 23 were directly related to pediatric cases of our interest. Medical records of the female patient, who has been treated in our center since 1991, were retrospectively described and reviewed. RESULTS Of 23 papers, we identified 75 cases of children who underwent ureteral substitution. The outcomes of the procedure are satisfactory and acceptable. The presented case of the female patient shows a good therapeutic option. CONCLUSION Ileal ureteral reconstruction is a safe and effective therapeutic option (even in a long-term follow-up). Despite many problems and complications, it allows preservation of renal and bladder function and social dryness.

Bilateral ileal ureter substitution for patients with ureteral strictures secondary to gynecological tumors radiotherapy: a multi-center retrospective study. Transl Androl Urol 2021; 10:3226-3238. [PMID: 34532248 PMCID: PMC8421837 DOI: 10.21037/tau-21-255] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Accepted: 05/24/2021] [Indexed: 11/15/2022] Open
Abstract
Background The selection of treatment for bilateral ureteral strictures caused by radiotherapy in patients with gynecological tumors often brings great challenges to urologists. This study was designed to analyze the characteristics of radiation-induced ureteral strictures and summarize the surgical experience of bilateral ileal ureter substitution. Methods We retrospectively collected the medical records of 18 patients between June 2010 and June 2019 who had a radiation-induced bilateral ureteral strictures. Time interval from radiotherapy to the discovery of ureteral stricture was categorized into short-term (less than 12 months) and long-term (over 12 months) groups. All patients received reverse “7” bilateral ileal ureteral substitution. Surgical success was defined as no restenosis, relief of symptoms, and improved/stabilized hydronephrosis. Results The patients had been suffered from ureteral stricture for a median of 12 [2–106] months. The mean length of the left and right ureteral stricture was 9.6±2.6 and 8.8±3.2 cm, respectively. The mean length of the ileal graft was 29.1±7.4 cm. The mean operative time was 308.4±70.2 min, and the mean estimated blood loss was 254.7±166.2 mL. The postoperative hospital stays in the short-term group was significantly shorter than that in the long-term group (14.0 vs. 20.6 days, P=0.049). During a median follow-up time of 24.1 (4.5–71.9) months, the success rate was 94.4%. Eight minor complications and two major complications occurred in 7 patients. Conclusions Bilateral ileal ureter substitution can be an effective strategy for radiation-induced ureteral stricture in patients with gynecological tumors.

Abstract
Background To present our experience with the "omental wrapping" technique in laparoscopic and robotic ureteroplasty using onlay flaps or grafts for the management of long proximal or middle ureteral strictures. Methods This is a retrospective review of 25 patients with long proximal or middle ureteral strictures who underwent laparoscopic and robotic onlay flaps or grafts ureteroplasty using an omental flap to reinforce an anastomosis site between August 2018 and November 2019. Perioperative and follow-up data were collected. Results Sixteen laparoscopic procedures and nine robotic procedures were performed successfully. Sixteen patients underwent ureteroplasty with lingual mucosal graft (LMG), and nine patients with appendiceal onlay flap (AOF). The median stricture length was 4 cm (range, 2-6 cm). The mean operative time (OT) was 220.5±50.6 min, the estimated blood loss (EBL) was 66.0±38.9 mL, and the length of hospital stay (LHS) was 8.0±3.6 days. In the LMG group, four patients had tongue numbing and one had an oral ulcer, which relieved itself gradually without intervention. Two patients in the LMG group and four patients in the AOF group experienced urinary tract infection, and all responded well to antibiotic treatment. There were no complications attributed to "omental wrapping". The mean follow-up was 16.3±4.8 months. According to the standards regarding improvement in clinical symptoms, relief of obstruction radiologically and a stable estimate glomerular filtration rate, our surgical success rate was 100%. Conclusions The "omental wrapping" technique in laparoscopic and robotic onlay flaps or grafts ureteroplasty for long proximal or middle ureteral strictures is an efficient, safe, reproducible and simple technique.

Abstract
PURPOSE OF REVIEW The purpose of this article is to outline the various therapeutic options of ureteral strictures. RECENT FINDINGS Ureteral strictures with consecutive hydronephrosis can be due to endourological and surgical procedures, inflammatory processes, radiation therapy as well as spontaneous passage of ureteral calculi. When planning surgical correction, stricture length, anatomical location as well as patients' characteristics like age, comorbidities and previous treatment in the peritoneal cavity, retroperitoneum or pelvis should be taken into consideration. Treatment options include not only surgical reconstruction techniques like simple stricture excision, end-to-end anastomosis, ureterolysis with omental wrapping, ureteroneoimplantation, renal autotransplantation and ureter-ileum replacement, but also minimally invasive procedures such as self-expandable thermostents and pyelovesical bypass prosthesis. SUMMARY Various therapeutic options can be offered in the treatment of ureteral strictures, potentially leading to long-term success rate of more than 90% and a rate of significant complications < 5%.

Abstract
OBJECTIVES Despite advances in surgical techniques and organ preservation, transplant ureteric strictures remain a common complication in kidney transplantation. A variety of endourological and surgical techniques have been utilized; however, there is a lack of consensus on the optimal modality in dealing with these complex cases. MATERIALS AND METHODS We present challenging ureteral reconstruction cases after failed attempts at ureteral dilatation, failed conventional open repairs, and/or with bladder dysfunction. RESULTS All renal allografts were salvaged by successful use of bladder Boari flap and intestinal segment interpositions/diversions. CONCLUSIONS Operative repair remains the most durable and successful approach, and minimally invasive options should be reserved for nonsurgical candidates, with consideration of a single attempt in patients with early, distal, short (<2 cm), nonischemic strictures.

Abstract
OBJECTIVE To analyze the etiology, characteristics, and ureteral reconstruction strategies of iatrogenic ureteric injuries in a high-volume center. METHODS Between September 2010 and August 2019, we retrospectively collected patients who underwent ureteral reconstruction due to iatrogenic ureteric injuries. Patient profiles, laboratory data, imaging studies, perioperative data, and complications were recorded. RESULTS Sixty-eight patients were enrolled in this study. The upper, middle, and lower thirds of the ureter were affected in 30, 2, and 36 cases, respectively. Of the 68 ureteric injuries, 69.1% occurred during urological procedures, followed by gynecological procedures, general surgery, radiotherapy, and orthopedic surgery. The majority of urological injuries (41, 87.2%) occurred due to stone removal. There was a significant difference in the age, sex, and location of ureteric injuries between the urological and nonurological groups. The median follow-up time was 17.9 months. The overall symptom remission rate was 91.2% and ranged from 87.5 to 100% for different reconstructive surgeries. CONCLUSIONS Urological procedures were the most common cause of iatrogenic ureteric injury; thus, extra care should be taken. Timely detection and appropriate treatment of the ureteric injuries are necessary. Treatment strategies should be depended on the location and length of injury.

Abstract
OBJECTIVES The aim of the study was to present our modified flap pyeloplasty techniques for recurrent ureteropelvic junction obstruction (UPJO) with a long proximal ureteral stricture and compare outcomes of laparoscopic and robotic procedures. MATERIALS AND METHODS Between March 2018 and January 2020, 21 patients underwent modified laparoscopic or robotic flap pyeloplasty for recurrent UPJO with a long proximal ureteral stricture. Our surgical modifications included the "wishbone" anastomosis and "ureteral plate" technique. Demographic, perioperative, and follow-up data were recorded and compared retrospectively between the groups. Success was defined as subjective pain alleviation and hydronephrosis improvement. RESULTS Thirteen modified laparoscopic flap pyeloplasty (mLFP) and 8 modified robotic flap pyeloplasty (mRFP) were performed successfully without conversion. mRFP tended to have shorter overall operative time (142.4 vs. 179.1 min, p = 0.122) and anastomosis time (43.1 vs. 61.0 min, p = 0.093) than mLFP. No difference was found in estimated blood loss (p = 0.723) and pararenal draining time (p = 0.175) between the groups. The mean postoperative hospital stay of mRFP was significantly shorter than that of mLFP (5.0 vs. 8.2 days, p = 0.015). No major complications occurred. During the mean follow-up of 17.9 months, the overall success rate was 90.5%, and there was no significant difference between 2 groups. CONCLUSIONS The modified flap pyeloplasty could be considered a practical and effective treatment option with a high success rate for recurrent UPJO with a long proximal ureteral stricture, and the robotic procedures showed advantages of higher efficiency and faster recovery.

Abstract
Background To evaluate the feasibility and effect of upper urinary tract videourodynamics in complex reconstructed upper urinary tract. Methods From January 2016 to December 2018, patients who underwent complex upper urinary tract reconstruction and received upper urinary tract videourodynamics were included in the study. The modified Whitaker test was performed at 3 months after operation. The relative pelvic pressure was defined as the pelvic pressure minus the bladder pressure. Based on the flow rate, the test was divided into physiological phase and high flow phase. The results of pressure and image were classified into 3 types. Successful nephrostomy removal was defined as no symptoms and improved or stable hydronephrosis. Results A total of 12 patients who underwent complex upper urinary tract reconstruction received modified Whitaker test. All tests were successfully completed without adverse reactions. The relative pelvic pressure of 3 patients kept steady near the baseline throughout the examination and was classified into type 1. The pelvic pressure of 7 patients increased as the perfusion continued, and the relative pressure dropped to relative low level due to the peristalsis of ureter (type 2). The pressure of 2 patients increased along with increasing perfusion speed, and the relative pelvis pressure could easily reach 15 cmH2O. The peristalsis of ureter disappeared or appeared very weakly on the video record (type 3). Patients in type 1 (3 cases) and type 2 (7 cases) groups were allowed to remove the nephrostomy tube immediately. Patients in type 3 group needed to keep the nephrostomy for close follow up, and the tubes were removed 2 weeks and 4 weeks after the examination, respectively. None of the 12 patients received further treatment for recurrent symptoms and exacerbation of hydronephrosis. Conclusions The modified Whitaker test is initially safe and feasible in postoperative evaluation of complex upper urinary tract reconstruction surgery. Detailed results can provide more evidence to judge whether nephrostomy tube could be removed safely.

Abstract
At the current stage of development of urology, selection of the surgical method for cases of severe obstructive diseases of the upper urinary system remains a challenge. This study aimed to explore the results of application of a buccal graft (BG) to remedy extended recurrent strictures and obliterations of the distal ureter. Seven patients with the mentioned diseases had undergone surgery: for six of them, the method of choice was complete BG ureteroplasty, one had onlay ureteroplasty. One intervention was laparoscopic, the remaining surgeries were open. The length of the replaced ureteral defect was 5–8 cm. In five cases, the flap was additionally vascularized with the iliac muscle, in one we used omentum tissue, in another — both the iliac muscle and the omentum. There were no fatalities registered, nor severe complications as per the Clavien–Dindo classification. The patients were followed-up for 4–18 months; as of today, no recurrence cases were identified. Control examinations showed complete patency of the neoureter and good vascularization of the BG. Thus, this method can be an option in cases disallowing distal ureter restoration with tissues of the patient's own urinary tract or segments of the gastrointestinal tract.

Abstract
INTRODUCTION Ileal ureter is a technique that consists of replacing the ureter by a segment of ileum to treat a long ureteric lesion or a lesion involving the lumbar ureter. The primary objective of our study was to assess the early perioperative morbidity of ileal ureter according to the Clavien-Dindo classification. The secondary objectives were to assess the morbidity and the medium- and long-term outcome of renal function. MATERIALS AND METHODS Single-centre retrospective study, collecting data from patients operated between February 2005 and October 2019. All patients who underwent ileal ureter replacement surgery in our unit were included in this analysis. The ureteric defect was longer than five centimetres and involved the pelvic and/or iliac and/or lumbar ureter. All ileal ureter replacements were performed by open surgery using isoperistaltic ileal grafts. RESULTS Twenty-one patients (11 women and 10 men) underwent total or subtotal, unilateral or bilateral ileal ureter replacement, corresponding to 25 kidneys. The grade III early postoperative complication rate was 9.5% (two cases) mainly consisting of bleeding. No grade IV or V complications were observed. With a mean follow-up of 85 months, long-term morbidity essentially consisted of infectious complications. No patients developed anastomotic strictures. Mean serum creatinine was 116.3μmol/L preoperatively, 105.6μmol/L one month postoperatively and 112.2μmol/L at last follow-up. Renal function was generally preserved or even improved, except for patients with preoperative renal failure. CONCLUSION Ileal ureter replacement is a surgical alternative associated with low morbidity and satisfactory long-term functional results. LEVEL OF EVIDENCE 3.

[PMID: 33258325 PMCID: PMC7801167 DOI: 10.4111/icu.20200298] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 07/24/2020] [Accepted: 08/06/2020] [Indexed: 01/01/2023] Open
Abstract
Purpose To report our intermediate-term, multi-institutional experience after robotic ureteral reconstruction for the management of long-segment proximal ureteral strictures. Materials and Methods We retrospectively reviewed our Collaborative of Reconstructive Robotic Ureteral Surgery (CORRUS) database to identify all patients who underwent robotic ureteral reconstruction for long-segment (≥4 centimeters) proximal ureteral strictures between August 2012 and June 2019. The primary surgeon determined the specific technique to reconstruct the ureter at time of surgery based on the patient's clinical history and intraoperative findings. Our primary outcome was surgical success, which we defined as the absence of ureteral obstruction on radiographic imaging and absence of obstructive flank pain. Results Of 20 total patients, 4 (20.0%) underwent robotic ureteroureterostomy (RUU) with downward nephropexy (DN), 2 (10.0%) underwent robotic ureterocalycostomy (RUC) with DN, and 14 (70.0%) underwent robotic ureteroplasty with buccal mucosa graft (RU-BMG). Median stricture length was 4 centimeters (interquartile range [IQR], 4–4; maximum, 5), 6 centimeters (IQR, 5–7; maximum, 8), and 5 centimeters (IQR, 4–5; maximum, 8) for patients undergoing RUU with DN, RUC with DN, and RU-BMG, respectively. At a median follow-up of 24 (IQR, 14–51) months, 17/20 (85.0%) cases were surgically successful. Two of four patients (50.0%) who underwent RUU with DN developed stricture recurrences within 3 months. Conclusions Long-segment proximal ureteral strictures may be safely and effectively managed with RUC with DN and RU-BMG. Although RUU with DN can be utilized, this technique may be associated with a higher failure rate.

Abstract
PURPOSE To present our experience of laparoscopic and robotic ureteroplasty using onlay flap or graft for the management of long proximal or middle ureteral strictures and summarize our treatment strategies for these challenging scenarios. METHODS From March 2018 to January 2020, 53 patients with long proximal/middle ureteral strictures (2-6 cm) who underwent laparoscopic or robotic onlay flap/graft ureteroplasty were retrospectively enrolled. Different reconstruction techniques were chosen based on our management strategy: pelvic flap (PF) was the first choice for proximal stricture if pelvic tissue was sufficient for repair, while appendiceal flap (AF) was preferred over oral mucosa graft for both proximal and middle strictures. RESULTS A total of 28 PFs, 9 AFs and 16 lingual mucosa grafts (LMGs) onlay ureteroplasty were performed successfully, with 33 laparoscopic procedures and 20 robotic procedures being undertaken. No intraoperative complications or conversion occurred. The median stricture length was 4 cm (range 2-6 cm). Compared with laparoscopic procedures, robotic procedures showed significantly shorter operative time (P = 0.008), shorter postoperative hospital stay (P = 0.011) but higher hospital cost (P < 0.001). At a mean follow-up of 12.8 months, the overall success rate was 94.3%. There was no difference in postoperative complications or the success rate between the approaches. CONCLUSION Laparoscopic and robotic onlay flap/graft ureteroplasty can be safe and feasible to repair long proximal/middle ureteral strictures while robotic procedures showed higher efficiency, faster recovery but higher cost. Our algorithmic strategies may provide beneficial references for their standardization and dissemination into clinical care.

Abstract
OBJECTIVE To summarize the experiences and outcomes of 108 robot-assisted laparoscopic upper urinary tract reconstruction surgeries conducted by a single surgeon. METHODS We consecutively and retrospectively reviewed 108 patients who underwent robot-assisted laparoscopic upper urinary tract reconstruction surgeries by a single surgeon from November 2018 to January 2020. The patient demographics, perioperative variables, postoperative complications and follow-up data were recorded. Fifty-three modified dismembered pyeloplasties (MDP), 11 spiral flap pyeloplasties (SFP), 11 ure-teroureterostomies (UUT), 4 lingual mucosal onlay graft ureteroplasties (LMU), 5 appendiceal onlay flap ureteroplasties (AU), 11 ureteral reimplantations (UR), 6 Boari flap-Psoas hitch surgeries (BPS) and 7 ileal ureter replacements (IUR) were enrolled finally. The success was defined as the improvement in subjective pain levels, and the improvement in the degree of hydronephrosis at ultrasound. RESULTS All the surgeries were successfully completed without open or laparoscopic conversion. The median operative time was 141 min (range: 74-368 min), median blood loss was 20 mL (range: 10-350 mL) and median hospital stay was 4 d (range: 3-19 d) in MDP group, with the success rate of 94.3%. The median operative time was 159 min (range: 110-222 min), median blood loss was 50 mL (range: 20-150 mL) and median hospital stay was 5 d (range: 3-8 d) in SFP group, with the success rate of 100%. The median operative time was 126 min (range: 76-160 d), median blood loss was 20 mL (range: 10-50 mL) and median hospital stay was 5 d (range: 4-9 d) in UUT group, with the success rate of 100%. The median operative time was 204 min (range: 154-250 min), median blood loss was 30 mL (range: 10-100 mL) and median hospital stay was 6 d (range: 4-7 d) in LMU group, with the success rate of 100%. The median operative time was 164 min (range: 135-211 min), median blood loss was 75 mL (range: 50-200 mL) and median hospital stay was 8.5 d (range: 6-12 d) in AU group, with the success rate of 100%. The median operative time was 149 min (range: 100-218 min), median blood loss was 20 mL (range: 10-50 mL) and median hospital stay was 7 d (range: 5-10 d) in UR group, with the success rate of 90.9%. The median operative time was 166 min (range: 137-205 min), median blood loss was 45 mL (range: 20-100 mL) and median hospital stay was 5 d (range: 4-41 d) in BPS group, with the success rate of 83.3%. The median operative time was 270 min (range: 227-335 min), median blood loss was 100 mL (range: 10-100 mL) and median hospital stay was 7 d (range: 5-26 d) in IUR group, with the success rate of 85.7%. CONCLUSIONS The surgeon performed and modified numerous complicated upper urinary tract reconstruction surgeries by the robotic platform, which facilitated the development of the standardized upper urinary tract reconstruction surgical technique.

Onlay Repair Technique for the Management of Ureteral Strictures: A Comprehensive Review. BIOMED RESEARCH INTERNATIONAL 2020; 2020:6178286. [PMID: 32775430 PMCID: PMC7407031 DOI: 10.1155/2020/6178286] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/05/2020] [Revised: 06/29/2020] [Accepted: 07/06/2020] [Indexed: 01/12/2023]
Abstract
Ureteroplasty using onlay grafts or flaps emerged as an innovative procedure for the management of proximal and midureteral strictures. Autologous grafts or flaps used commonly in ureteroplasty include the oral mucosae, bladder mucosae, ileal mucosae, and appendiceal mucosae. Oral mucosa grafts, especially buccal mucosa grafts (BMGs), have gained wide acceptance as a graft choice for ureteroplasty. The reported length of BMG ureteroplasty ranged from 1.5 to 11 cm with success rates of 71.4%-100%. However, several studies have demonstrated that ureteroplasty using lingual mucosa grafts yields better recipient site outcomes and fewer donor site complications than that using BMGs. In addition, there is no essential difference in the efficacy and complication rates of BMG ureteroplasty using an anterior approach or a posterior approach. Intestinal graft or flap ureteroplasty was also reported. And the reported length of ileal or appendiceal flap ureteroplasty ranged from 1 to 8 cm with success rates of 75%-100%. Moreover, the bladder mucosa, renal pelvis wall, and penile/preputial skin have also been reported to be used for ureteroplasty and have achieved satisfactory outcomes, but each graft or flap has unique advantages and potential problems. Tissue engineering-based ureteroplasty through the implantation of patched scaffolds, such as the small intestine submucosa, with or without cell seeding, has induced successful ureteral regeneration structurally close to that of the native ureter and has resulted in good functional outcomes in animal models.

Abstract
Nephrogenic adenoma is a rare, benign lesion that can be encountered anywhere along the urinary tract. It is associated with genitourinary trauma, chronic inflammation, genitourinary surgery, renal transplant, urolithiasis, and radiation. In children, these lesions are almost exclusively found in the bladder. However, we report an unusual case of a 15-year-old boy with no prior urologic history who presented with an obstructing right ureteral nephrogenic adenoma that required an ileal ureter interposition and right ureterectomy.

Abstract
Long ureteral defects have remained a challenge to urologists for a long time. Bowel interposition, including ileal ureter, appendiceal interposition and reconfigured colon substitution, has gained wide acceptance, even though it is a complicated procedure and associated with some potential complications. Mucus obstruction and metabolic disorders are common complications of intestinal substitution. To circumvent these troubles, modified techniques, such as tapering the bowel graft, intestinal onlay flap and the Yang-Monti procedure, are used. In particular, Yang-Monti ileal ureter replacement is a highly effective option for ureteral reconstruction, and the incidence of complications would be significantly reduced in select patients. After being combined with the Boari flap or psoas hitch technique, the length of intestinal segment used can also be significantly reduced. Most recent long-term results suggest that ileal ureter replacement with antireflux anastomosis seems to be remarkably free of complications, and we highly praise the distal nipple valve technique. Appendiceal interposition is available for patients with normal appendix, and usually this procedure is limited to reconstructing the right ureter. Appendiceal onlay ureteroplasty has emerged as a feasible and effective option to manage patients with complex proximal and mid-ureteral strictures of the right side. The colon is rarely used for ureteral reconstruction because of its large caliber and mucous surface area. However, a reconfigured colon segment is a good substitute to reconstruct long-segment ureteral defects, and long-term follow up confirmed minimal complications and improved renal function. This review provides a comprehensive perspective on complex ureteral reconstruction and replacement using intestinal segments, in particular, ileal ureter replacement.

Abstract
Purpose To report a single surgeon experience with one year follow-up after open ureteroplasty with buccal mucosa graft (OUBMG) in the rare situation of long segment proximal ureteral strictures. Materials and Methods Four patients with long segment proximal ureteral stricture underwent OU-BMG between February and July 2017. Functional outcome was assessed by pre- and postoperative serum creatinine, ultrasound and renal scintigraphy as well as patient reported outcomes. Results Four patients with an average stricture length of 4 cm underwent OU-BMG between February and July 2017. No major postoperative complications occurred. Retrograde uretero-pyelography 6 weeks postoperatively revealed a watertight anastomosis followed by immediate emptying of the renal pelvis and ureter in all four patients. Ureteroscopy at this time showed a wide lumen with well-vascularized pink mucosa. After a mean follow-up time of 12.5 (12–14) months, postoperative serum creatinine was unimpaired. Renal scintigraphy revealed no signs of renal obstruction. With regard to intraoral surgery, no difficulties with mouth opening or intraoral dryness or numbness were reported. Conclusions For patients with long segment ureteral strictures OU-BMG is a safe technique with excellent surgical and functional outcomes. Hence, the application of this technique should be encouraged and regarded as one of the standard options in case of this rare problem.

Abstract
Ureteral injury can be classified as iatrogenic or traumatic, which represents a rare but challenging field of reconstructive urology. Due to their close proximity to vital abdominal and pelvic organs, the ureters are highly susceptible to iatrogenic injury, while ureteral injury caused by external trauma is relatively rare. The signs of ureteric injury are difficult to identify initially and often present after a delay. The treatment of ureteral injury, which is depended on the type, location, and degree of injury, the time of diagnosis and the patient's overall clinical condition, ranges from simple endoscopic management to complex surgical reconstruction. And long defect of the ureter presents much greater challenges to urologists. Ureterotomy under endoscopy using laser or cold-knife is available for the treatment of 2-3 cm benign ureteral injuries or strictures. Pyeloplasty is an effective treatment for ureteropelvic junction obstruction and some improved methods showed the possibility of repairing long-segment (10-15 cm) stenosis. Proximal and mid-ureteral injuries or strictures of 2-3 cm long can often be managed by primary ureteroureterostomy. When not feasible due to ureteral defects of longer segment, mobilization of the kidney should be considered, and transureteroureterostomy is alternative if the proximal ureter is of sufficient length. And autotransplantation or nephrectomy is regarded as the last resorts. Most of the injuries or strictures are observed in the distal ureter, below the pelvic brim, and are usually treated with ureteroneocystostomy. A non-refluxing technique together with a ureteral nipple or submucosal tunnel method, is preferable as it minimizes vesico-ureteral reflux and the risk of infection. In order to cover a longer distance, ureteroneocystostomy in combination with a psoas hitch (covering 6-10 cm of defect) or a Boari flap (covering 12-15 cm) is often adopted. Among various ureteral replacement procedures, only intestinal ureteral substitution, which includes ileal ureter, appendiceal interposition and reconfigured colon substitution, has gained wide acceptance when urothelial tissue is insufficient. Ileal ureter can be used to replace the ureter of >15 cm defect and even to replace the entire unbilateral ureter or bilateral ureter. Laparoscopic and robotic-assisted techniques are increasingly being employed for ureteral reconstruction and adopted with encouraging results.

Abstract
Upper urinary surgery is an important area of urology surgery. Open surgery used to be the gold standard of upper urinary surgery. With the development of medical techniques, minimal invasive surgeries including laparoscopic and robot assisted-laparoscopic surgery have gradually replaced the open surgery. Because of the complexity and diversity of upper urinary diseases, surgeries sometimes are difficult, and minimal invasive surgeries require higher surgical abilities of urologists than open surgeries. In recent years, depending on our surgical experience and international reports, our team from three Chinese medical centers summarizes techniques of upper urinary minimal invasive surgeries. For malignant diseases, such as renal and ureteral carcinomas, it's important to totally remove the tumor first, and then to avoid the surgical injuries. We summarize surgical experience of retroperitoneal laparoscopic partial nephrectomy for moderately complex renal hilar tumors. Our team modified minimal invasive techniques for some complex tumors, including ring suture technique for renal hilar tumors, internal suspension technique for renal ventral tumors, and combination retroperitoneal laparoscopic surgery with mini-flank incision for complex renal tumors. While for begin diseases, urologists should focus on the resections and surgical injuries at the same time. We have reported the novel technique of laparoscopic aspiration for central renal angiomyolipoma, making the surgery simple and available. For reconstruction surgeries, operations should be based on several principals. We generalize it as "4TB principals", which include "tension-free", "water-tight", "thin suture", "no touch of the key area" and "protecting the blood supply". Depending on the localization, length, and etiology of the strictures, different techniques are required. Our team summarize the pyeloplasty, ureteral reimplantation and ileal ureter replacement based on our surgical experience. For infant upper urinary surgeries, our team has made invasive surgeries that can be used in complex diseases, such as duplex kidney. Based on years of surgical techniques, our modified surgeries achieve a better subjective cosmetic result than the traditional surgeries. In the future, the standardized, practical, simple and individual minimal invasive surgical technique will become the main direction in the future researches.

Organ-sparing procedures in GU cancer: part 3-organ-sparing procedures in urothelial cancer of upper tract, bladder and urethra. Int Urol Nephrol 2019; 51:1903-1911. [PMID: 31352580 DOI: 10.1007/s11255-019-02232-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2019] [Accepted: 07/10/2019] [Indexed: 10/26/2022]
Abstract
PURPOSE The impact of radical surgery for urothelial carcinoma is significant on patient's quality of life. Organ-sparing surgery (OSS) can provide comparable oncological outcomes and with improved quality of life. In this review, we summarize the indications, techniques and outcomes of OSS for these tumors. METHODS PubMed® was searched for relevant articles. Keywords used were: for upper tract urothelial carcinoma (UTUC): endoscopic, ureteroscopic/percutaneous management, laser ablation; for urothelial bladder cancer: bladder preservation, trimodal therapy, muscle invasive bladder cancer (MIBC); for urethral cancer: urethra/penile-sparing, urethral carcinoma. RESULTS Kidney-sparing surgery is an option in patients with low-risk UTUC with better renal function preservation and comparable oncological control to radical nephroureterectomy. In select patients with MIBC, trimodal therapy has better quality of life and comparable oncological control to radical cystectomy. In distal male urethral cancer, penile conserving surgery is feasible and offers acceptable survival outcomes. In female urethral cancer, organ preservation can be achieved, in addition to OSS, through radiation. CONCLUSIONS In the appropriately selected patient, OSS in upper tract, bladder and urethral carcinoma has comparable oncological outcomes to radical surgery and with the additional benefit of improved quality of life.

BMC Surg 2019; 19:9. [PMID: 30658620 PMCID: PMC6339271 DOI: 10.1186/s12893-019-0472-1] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2017] [Accepted: 01/04/2019] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND Ileal ureter replacement is an alternative treatment for various length ureter defects. We present our experience and outcome of ileal ureter replacement in China. METHODS We retrospectively collected data of patients who underwent ileal ureter replacement between January 2010 and January 2015. We reviewed the medical history, indications for surgery, operative data, perioperative data, and outcomes. Besides, follow-up data included symptom, urine routine test, serum creatinine, serum electrolyte status, and radiographic test. RESULTS There were 23 patients who underwent ileal ureter replacement by the same surgeon. Twenty patients were performed unilateral ileal ureter replacement, two patients underwent a combination of ileal ureter replacement and Boari flap-psoas hitch, and one received bilateral ileal ureter replacement. Among these patients, the main cause leading to surgical treatment was iatrogenic injuries (n = 15), especially urinary surgery procedure (n = 11). The median follow-up time was 45 months. There were 6 early complications and 6 late complications after operation. Only one patient suffered from small bowel-related complication and was cured by conservative treatment. Only the patient who underwent bilateral ileal ureter replacement had metabolic acidosis. And 22 patients (95.7%) had a good renal function. CONCLUSIONS Ileal ureter replacement is an efficacious and safe procedure for the therapy of long ureteral defects. With appropriate technical considerations, the complication rate may decrease.

Abstract
OBJECTIVE To assess perioperative, clinical, and functional outcomes following completely robotic ileal ureter. METHODS We retrospectively reviewed 7 consecutive patients undergoing completely intracorporeal ileal ureteric replacement between November 2015 and May 2017. One patient had a solitary kidney. A 4-arm technique was used. In 5 patients, additional psoas hitch procedure was performed. Patients had retrograde filling and removal of the ileal stent and transurethral catheter at an average of 14 days postoperatively. Renal ultrasonography, serum analysis, and diuretic renography were performed at follow-up 3 months postoperatively. RESULTS Mean operative time was 328 ± 66.3 minutes and median estimated blood loss was 100 mL (range 50-200); mean length of the ileal substitute was 20.4 cm (range 18-24). No case was converted to open surgery. In 1 patient, there was a prolonged insufficiency of the pyeloileal anastomosis, requiring prolonged stenting. Apart from that, there were no major complications and no open surgical or endoscopic reinterventions. On 3-month follow-up, all patients presented symptom-free, with no signs of obstruction on ultrasound and significantly improved glomerular filtration rate, creatinine levels, and differential renal function (P = .02, 0.03, and 0.046, respectively). Five patients had a diuretic halftime <10 minutes, 2 had a halftime between 10 and 20 minutes. CONCLUSION Completely intracorporeal robotic ileal ureteric replacement results in full functional restoration of the upper tract in cases of long defects of the mid and upper ureter.

Use of the Ileum for Ureteral Stricture and Obstruction in Bilateral, Unilateral, and Single-kidney Cases. Urology 2017; 111:203-207. [PMID: 28818535 DOI: 10.1016/j.urology.2017.08.008] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2017] [Revised: 07/21/2017] [Accepted: 08/02/2017] [Indexed: 11/20/2022]
Abstract
OBJECTIVE To investigate the functional outcomes of ileal ureter replacement for complex ureteral loss, including bilateral and single ureter stricture, as a result of various etiologies. METHODS In 2013-2016, 31 patients underwent ileal ureter replacement surgery. The data for their assessments included etiology, combined surgical procedures, ureteral replacement type, postoperative complications, and changes in renal function. RESULTS The 31 study patients had a median age of 56.0 (range 18-65) years and were followed for a median of 23.6 (range 6.5-43.2) months. There were 14 bilateral, 12 unilateral, and 5 single-kidney cases. The main indication for surgery was ureteral defects after gynecological surgery and radiation in 24 patients (77.4%). The mean operation time was 370.6 minutes and the median hospital stay was 25.2 (range 6-79) days. Various types of ileal arrangement were performed to cover bilateral ureter loss. After 30 days past surgery, 24 patients (77.4%) were in a stable state and 5 (16.1%) had decreased serum levels of creatinine. Short-term complications greater than grade 3 on the Clavien scale occurred in 10 patients (33.3%), and long-term complications occurred in 27 (87.1%). However, all cases were well relieved by conservative care, and surgical intervention was needed in only 1 case. Apart from 2 patients who died because of the progression of cervical cancer, all patients had stent-free status at 22.4 months. CONCLUSION Ileal ureter replacement is a useful reconstructive surgery for complex ureteral loss, such as bilateral and single-kidney cases resulting from various etiologies.

Ileal Ureter Replacement Combined With Boari Flap-Psoas Hitch to Treat Full-Length Ureteral Defects: Technique and Initial Experience. Urology 2017; 108:201-206. [PMID: 28739403 DOI: 10.1016/j.urology.2017.07.014] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2017] [Revised: 06/17/2017] [Accepted: 07/11/2017] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To evaluate the feasibility of ileal ureter replacement combined with Boari flap-psoas hitch procedure for the management of full-length ureteral defects (>20 cm). METHODS Three patients diagnosed with full-length ureteral defect were treated with our technique performed by a single surgeon between January 2015 to January 2016. All the patients had borderline renal function preoperatively. In each case, the ureteral reconstruction was performed by combining ileal ureter replacement with Boari flap-psoas hitch. Data on indications for surgery, intraoperative and postoperative outcomes, and changes in renal function were collected. RESULTS Surgery was performed successfully with an operation duration between 210 and 250 minutes. The mean estimated blood loss was 230 mL. The mean length of hospital stay was 11 days, and no major complications (grade ≥3) occurred. Postoperative follow-up showed radiological resolution of hydronephrosis and improved renal function in all 3 patients. CONCLUSION Ileal ureter replacement combined with Boari flap-psoas hitch is a feasible option for bridging full-length ureteral defects. This technique minimizes the length of ileal graft required as well as limitations concerning patient selection. Larger series with longer follow-up to confirm the value of the technique are warranted.
