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
Purpose: To evaluate functional outcomes of robot-assisted ureteroplasty with labial mucosa grafting for long proximal ureteral stenosis (LPUS) in children and adolescents. Methods: Included in this study were 15 patients who underwent robot-assisted ureteroplasty with labial mucosal grafting in our center between July 2017 and September 2021. The left affected stenotic ureter was repaired using labial mucosal grafting. If the ureter was simply strictured but not obliterated, the ureter was spatulated longitudinally along the ventral side and the labial mucosa graft was interposed and anastomosed in a continuous manner. Faced with the obliterated segment, it was excised and the spatulated portion re-anastomosed with a pelvic flap as the dorsal wall. The labial mucosa graft was placed as the ventral wall. The preoperative clinical data and follow-up outcomes were collected and evaluated. Results: Labial mucosa graft onlay ureteroplasty was well performed in all the 15 patients with no occurrence of intraoperative complications or surgical conversion. Five patients underwent an onlay ureteroplasty, and 10 patients underwent a dorsally augmented pelvic flap anastomotic ureteroplasty. The mean (range) stricture length was 7.1 (3-10) cm. The mean operative time was 371.2 (216-480) minutes, and the median blood loss was 40 mL. At the median follow-up of 35 months (range 12-58 months), the overall success rate was 93.3%. Conclusions: Labial mucosa grafting appears to be safe and feasible for repairing long ureteral strictures in pediatric and adolescent patients. Our experience may provide beneficial references and conveniences to solve complex problems in LPUS. This study was approved by the institutional review board, and written informed consent was obtained from each participant (ethics number: 2017-30).

Abstract
OBJECTIVES To describe outcomes of oral mucosal graft ureteroplasty (OMGU) and ileal ureter replacement (IUR) and determine the relative merits of both procedures. METHODS Databases (including PubMed, Embase and Cochrane) were interrogated for eligible trials that assessed outcomes of OMGU or IUR from 2000 to 30 July 2022. The variables analysed were reconstruction success rates, stricture length, hospital stays, perioperative complications and long-term complications. RESULTS A total of 23 single-arm studies were included. The pooled reconstruction success rates for OMGU and IUR were 94.9% (95% confidence interval [CI] 91.0%-97.7%) and 85.8% (95% CI 81.0%-90.0%), respectively. Stricture length of patients in the OMGU and IUR groups were 3.73 (95% CI 3.17-4.28) and 11.55 (95% CI 9.82-13.29) cm, respectively. The maximal stricture length repaired by OMGU was 8 cm. The hospital stays were 5.85 (95% CI 3.88-7.82) and 11.55 (95% CI 6.93-16.17) days in the OMGU and IUR groups, respectively. The incidences of low-grade postoperative complications were 13.6% (95% CI 6.9%-20.3%) and 27.3% (95% CI 19.5%-35.1%), high-grade postoperative complications were 4.6% (95% CI 1.8I-8.5%) and 13.0% (95% CI 9.4%-17.1%), and long-term complications (occurred at > 3months) were 9.0% (95% CI 1.7%-20.0%) and 35.4% (95% CI 25.8%-45.6%) in the OMGU and IUR groups, respectively. CONCLUSION An OMGU is an effective, minimally invasive, and safe alternative to IUR for the management of long ureteric strictures. OMGU was the preferred treatment for long ureteric strictures, especially obstructed ureter segments of ≤8 cm.

Abstract
ZIEL DER STUDIE Beschreibung einer neuen Technik zur Rekonstruktion von komplexen Ureterstrikturen unter Verwendung eines freien Peritoneallappens. MATERIAL UND METHODEN Zwischen 2006 und 2021 behandelten wir 11 Patienten mit langen komplexen Harnleiterstrikturen, die in 9 Fällen den mittleren- und in 2 Fällen den proximalen Harnleiter betrafen. Die Länge der Strikturen variierte von 3 bis 12 cm (Mittelwert 7 cm). In drei Fällen handelte es sich um eine retroperitoneale Fibrose nach einem gefäßchirurgischen Eingriff, in zwei Fällen um einen Morbus Ormond, in vier Fällen um eine ausgedehnte Resektion großer Harnleitertumoren, in drei Fällen um wiederholte endoskopische Eingriffe bei Harnsteinen und in einem Fall um eine viermal fehlgeschlagene Pyeloplastik. Der Harnleiter wurde längs gespalten, ein freier Peritoneallappen aus dem nahe gelegenen gesunden Bauchfell entnommen und nach Positionierung eines Harnleiterkatheters als Onlay-Patch mit einer fortlaufenden Naht an der verbleibenden Harnleiterplatte fixiert. Der Ureter wurde zuletzt mit Omentum gedeckt. ERGEBNISSE Die Nachbeobachtungszeit reichte von 12 bis 122 (Mittelwert 61,6) Monate. Sieben Patienten waren nach 12, 18, 60, 78, 98, 99 und 122 Monaten (Mittelwert 69,5 Monate) rezidivfrei, ohne Erweiterung des oberen Harntrakts und mit normaler Nierenfunktion. Bei vier Patienten kam es zu einem Rezidiv: Bei einem Patienten wurde das Rezidiv nach 60 Monaten ohne Symptome und mit leichter Hydronephrose festgestellt, ohne dass eine Operation erforderlich war. Bei einem Patienten mit Morbus Ormond trat das Rezidiv 6 Monate nach dem Eingriff symptomlos im distalen Teil des 10 cm langen Omlays auf. Es wurde eine Resektion des stenotischen Segments mit Psoas-Hitch durchgeführt. Bei den beiden anderen Patienten trat 3 und 6 Monate nach dem Eingriff eine Obstruktion unterhalb des rekonstruierten Segments mit Hydronephrose auf, ohne dass die Nierenfunktion beeinträchtigt war. Bei diesen Patienten wurde keine weitere Operation durchgeführt. Die Limitation dieser Studie besteht in der kleinen Studiengröße, die auf die strenge Indikationsstellung zurückzuführen ist. SCHLUSSFOLGERUNGEN Die beschriebene Technik ermöglicht den Erhalt der verbleibenden Gefäßversorgung des Harnleiters und stellt eine praktikable und nützliche Alternative zu Nephrektomie, Ileum-Ureter, Uretero-Uretero-Stomie und Autotransplantation in hochselektierten Fällen dar.

Abstract
Introduction Redo pyeloplasty can be difficult due to scar tissue or fibrosis. Ureteral reconstruction with a buccal mucosal graft is performed safely and successfully, but most reports of ureteral reconstruction using a buccal mucosal graft are of robot-assisted surgery, with few reports of laparoscopic-assisted surgery. A case of laparoscopic-assisted redo pyeloplasty using a buccal mucosal graft is presented. Case presentation A 53-year-old woman was diagnosed with ureteropelvic junction obstruction, and a double-J stent was placed to relieve backache. She visited our hospital 6 months after double-J stent placement. Three months later, laparoscopic pyeloplasty was performed. At 2 months postoperatively, anatomic stenosis occurred. Holmium laser endoureterotomy and balloon dilation were performed; however, the anatomic stenosis recurred, and laparoscopic redo pyeloplasty with a buccal mucosal graft was performed. After redo pyeloplasty, obstruction was improved, and her symptoms disappeared. Conclusion This is the first case of using a buccal mucosal graft for laparoscopic pyeloplasty in Japan.

Abstract
PURPOSE Ureteroplasty with a lingual mucosa graft (LMG) for complex ureteral stricture was reported promising. We aimed to compare outcomes of robotic versus laparoscopic ureteroplasty using a LMG (RU-LMG vs. LU-LMG, respectively). METHODS From October 2018 to January 2021, 32 ureteroplasties using LMGs were performed by one experienced surgeon, including 16 robotic and laparoscopic procedures each. Patient demographics and peri-operative, post-operative, and follow-up data were prospectively collected and compared. RESULTS The robotic group had a higher rate of previous reconstruction than the laparoscopic group (62.50% vs. 18.75%; p = 0.012). The stricture length was significantly longer in the robotic group (4.8 ± 1.2 cm) than the laparoscopic group (3.7 ± 1.2 cm; p = 0.013). All procedures were completed successfully without open conversion. The operative time was shorter in the robotic group (192 ± 54 min) than the laparoscopic group (254 ± 46 min; p = 0.001). The robotic group had a shorter length of post-operative stay (6.1 ± 2.4 d vs. 8.9 ± 4.3 d; p = 0.033) but a higher hospital cost (76,801 ± 17,974 vs. 42,214 ± 15,757 RMB; p < 0.001) than the laparoscopic group. The mean follow-up time was 21 ± 7 months for the robotic group and 29 ± 9 months for the laparoscopic group respectively (p = 0.014). No difference was detected in the success rate (93.75% and 100%, respectively; p = 0.309) and complication rate (18.75% and 31.25%, respectively; p = 0.414) between the robotic and laparoscopic groups. CONCLUSION Both RU-LMG and LU-LMG are feasible, effective, and safe for repair of complex ureteral strictures. RU-LMG had a shorter operative time and a shorter length of post-operative stay but a higher hospital cost.

Abstract
OBJECTIVE The buccal mucosa graft (BMG) is the standard graft for reconstructive urology, but management of the donor site remains under debate. The authors compared postoperative oral adverse outcomes between management methods (closure, nonclosure, or xenograft-assisted closure). STUDY DESIGN A retrospective cohort study was conducted, enrolling patients treated at Harborview Medical Center, Seattle, Washington. The patients had a history of urethroplasty using a unilateral BMG, and the primary outcome variables were postoperative oral adverse outcomes, defined as subjective changes in mouth opening, smile, chewing, speech, intraoral bleeding, paresthesia, trismus, and infection. Multivariate and regression analyses were performed. RESULTS The sample was composed of 137 patients (95% male; mean age, 48 years). The mean surface areas of the BMG for closure, nonclosure, and xenograft were 1059, 1178, and 1228 mm2, respectively. Thirty-four patients completed the survey (7 closure, 17 nonclosure, and 10 xenograft). Multiple linear regression showed a significant difference between the 3 groups with respect to patient-reported chewing ability and trismus favoring xenograft at larger graft sizes (P < .01). CONCLUSIONS Xenograft-assisted closure may reduce long-term oral adverse outcomes associated with trismus and subjective changes in chewing, mouth opening, speaking, and smiling with larger grafts. In addition, limited postoperative patient education for oral rehabilitation exercises was noted.

Lingual Mucosal Graft Ureteroplasty for Long Proximal Ureteral Stricture: 6 Years of Experience with 41 Cases. Eur Urol 2022; 82:193-200. [PMID: 35618522 DOI: 10.1016/j.eururo.2022.05.006] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 03/26/2022] [Accepted: 05/10/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Management of a long proximal ureteral stricture is challenging. Lingual mucosal graft ureteroplasty (LMGU) is a novel minimally invasive technique for ureteral reconstruction that avoids the morbidity of bowel interposition or autotransplantation. OBJECTIVE To evaluate the long-term effectiveness of LMGU for managing long, complex proximal ureteral strictures in a multi-institutional cohort of patients. DESIGN, SETTING, AND PARTICIPANTS This retrospective study involved data for 41 patients treated with LMGU at three centers between June 2015 and January 2021. SURGICAL PROCEDURE LMGU was performed using either an onlay ureteroplasty in which the diseased ureter was incised ventrally and repaired with a lingual mucosal graft (LMG) to widen the ureteral lumen, or an augmented anastomotic technique in which the obliterated segment of the ureter was excised and reanastomosed primarily on dorsal side, and an LMG was placed on the ventral side. MEASUREMENTS Pre-, intra-, and postoperative variables and outcomes were assessed. A descriptive statistical analysis was performed. RESULTS AND LIMITATIONS Of 41patients, 40 were operated with laparoscopic procedures and one with a robot. Twenty-four (59%) patients underwent an onlay ureteroplasty, and 17 (41%) underwent an augmented anastomotic ureteroplasty. The reconstructed ureter was wrapped with omentum in 90% of cases. The median (range) stricture length was 4.8 cm (2.0-8.0), operative time was 166 min (98-306), and estimated blood loss was 65 ml (15-220). No open conversions and intraoperative complications occurred. At a median follow-up of 35 mo (range 13-80), the overall success rate was 97.6% (40/41). CONCLUSIONS LMGU is a safe, feasible, and effective long-term technique for managing long, complex proximal ureteral strictures. PATIENT SUMMARY We reported a novel technique for long proximal complex ureteral strictures using an onlay lingual mucosal graft (LMG). Our 6-yr outcomes demonstrate that onlay LMG ureteroplasty is a safe, feasible, and effective long-term procedure for ureteral reconstruction.

Abstract
Background To analyze the safety and clinical significance of performing ureteroscopy after ureteral reconstruction with autologous onlay/graft. To describe the ureteroscopic appearances of the appendiceal onlay flap and lingual mucosa graft. Methods Beginning in August 2018, we conducted a prospective cohort study of autologous onlay/graft techniques to repair ureteral strictures. The perioperative data of 42 patients who had undergone surgery more than 6 months prior were collected prospectively. During the postoperative follow-up, ureteroscopy was performed in 27 patients (64.3%) after surgery (group A), and ureteroscopy was not performed in the other 15 patients (35.7%) (group B). We carried out a comparative study of these two groups of patients. Analyses were conducted mainly on complications related to ureteroscopy and the success rate of ureteral reconstruction surgery. Results There were no significant differences in patient demographic data or the length of ureteral reconstruction between the two groups (P>0.05). For the ureteroscopy group, the median time from repair surgery to ureteroscopy was 3 (range, 2-7) months, there was no poor healing of the anastomosis, and the ureteral lumen of all patients was unobstructed. Some expected observations can be found in the ureteral lumen, such as mucosa edema, stones, follicles and granulation tissue. Among the 27 patients, one patient (3.7%) developed bleeding intraoperatively and 7 patients (25.9%) were found to have low-grade (Clavien-Dindo I and II) postoperative complications, including 5 cases of fever and 2 cases of bleeding. The mean follow-up times of patients in group A and group B were 16.7±6.4 and 19.0±10.1 months, respectively. The objective success (imaging showed hydronephrosis ease) rate of the two groups was 100%. The subjective success (symptom relief) rates of group A and group B were 96.3% and 100%, respectively. Conclusions Patients after autologous onlay flap/graft ureteroplasty do not need to undergo routine ureteroscopy unless there is aggravation of hydronephrosis or other indications for ureteroscopy, such as stones.

Validation of robotic-assisted ureteroplasty with buccal mucosa graft for stricture at the proximal and middle ureters: the first comparative study. J Robot Surg 2021; 16:1009-1017.

Abstract
Although ureteroplasty with buccal mucosa graft for long-segmental ureteral stenosis has been developed long ago, evidence was still restricted to case series in published literature. This study aims to validate ureteroplasty with buccal mucosa graft (BMG) in long-segment stricture at the proximal and middle ureters under designed comparative methods. From April 2015 to January 2019, we performed robotic-assisted ureteroplasty with BMG with a two-phase design and compared ureteroplasty and BMG (phase 2 surgery) with endoscopic stenting (phase 1 surgery). Paired data of effective renal plasma flow (ERPF), glomerular filtration rate (GFR), hydronephrosis grade, and physical and psychological domains of the World Health Organization Quality of Life (WHOQOL)-BREF were compared. A total of 29 patients were enrolled, and only three (10%) patients had hydronephrosis resolution after treatment with endoscopic stenting (p = 0.250 to baseline). Compared to endoscopic ureteral stent, Hedges' g of ureteroplasty with BMG was 0.56 (95% CI 0.43-0.69), 0.63 (95% CI 0.46-0.80), 0.80 (95% CI 0.56-1.04), and 1.06 (95% CI 0.69-1.43) in EGFR, GFR, physical domain of WHOQOL-BREF, and psychological domain of WHOQOL-BREF, respectively (All significance; p < 0.001). After 12-month follow-ups, no recurrence of stricture was reported. In conclusion, Robotic-assisted ureteroplasty with BMG onlay is efficient in reconstruction of long-segment stricture of the proximal and middle ureters.

Ureteral reconstruction for complex strictures: a review of the current literature. Int Urol Nephrol 2021; 53:2211-2219. [PMID: 34524628 DOI: 10.1007/s11255-021-02985-6] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Accepted: 09/03/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE Frequently employed procedures for ureteral reconstruction include balloon dilation, pyeloplasty and ureteral re-implants. However, these procedures do not work for complex ureteral disease. The goal of this literature review is to report on techniques and success rates for the following techniques: buccal graft ureteroplasty, appendiceal interposition, transureteroureterostomy, ileal ureter and autotransplantation. METHODS A comprehensive literature search for English-language original and review articles was conducted using PubMed. The following terms were queried: "ureteral reconstruction", "buccal graft", "appendiceal interposition", "ileal ureter", "transureteroureterostomy", "autotransplantation". RESULTS Procedures involving the buccal mucosa or appendix offer minimally invasive techniques and low morbidity with good short-term success. Drawbacks to appendiceal interposition include the availability and length of appendix, and 10-20% of patients may have insufficient appendix upon intra-operative assessment. Transureteroureterostomy is typically limited to extensive exonerations due to concerns of injury to the contralateral kidney, even with reported success rates > 90%. Ileal ureter may carry a risk of metabolic acidosis in patients with renal insufficiency along with bowel-related complications. Ileal ureter and autotransplantation are reserved for the most severe cases due to their high morbidity but do offer options for the complex patient. CONCLUSION Ureteral stricture disease not amenable to pyeloplasty, ureteroureterostomy or ureteroneocystostomy offers a challenge to urologist. Careful patient selection with pre-operative assessment of renal and bladder is vital to a successful operation with minimal complications.

Abstract
PURPOSE OF REVIEW To provide an overview and description of the different surgical techniques for the robotic repair of ureteral strictures. RECENT FINDINGS The robotic repair of ureteral stenosis has emerged as a useful option for treating strictures unsuitable for endoscopic resolution with good results, lower morbidity, and faster recovery than open techniques. Depending on the stricture's length and location, the reconstructive options are reimplantation, psoas hitch, Boari flap, ureteroureterostomy, appendiceal onlay flap, buccal mucosa graft (BMG) ureteroplasty, ileal replacement, or renal autotransplantation. The robotic approach offers a magnified vision and the possibility of adding near-infrared fluorescence (NIRF) imaging, indocyanine green (ICG), and FireflyTM to facilitate the technique. Multicenter studies with extended follow-up still have to confirm the good results obtained in published case series. Robotic reconstructive techniques are useful for repairing ureteral strictures, obtaining good functional results with less morbidity and faster recovery than open procedures.

Abstract
The advent and success of buccal mucosal grafts as a substitution material in the urinary tract has changed the landscape of reconstructive urology. Due to its ease to harvest, low morbidity, and advantageous properties, there has been a growing number of applications for buccal mucosal grafts in upper and lower urinary tract reconstruction as well as genital reconstruction. In this article, we review the historical application and the evolution of buccal mucosal grafts and provide an up-to-date review on its utilization in urologic procedures.

Abstract
Objective: To share the technique of posteriorly augmented anastomotic ureteroplasty with lingual mucosal onlay grafts for long proximal ureteral strictures as well as our initial experience with the technique. Methods: From October 2018 to September 2019, 10 cases of robotic and laparoscopic posteriorly augmented anastomotic ureteroplasty with lingual mucosal onlay grafts for long proximal ureteral strictures were recruited from our database of Reconstruction of Urinary Tract: Technology, Epidemiology and Result (RECUTTER). The perioperative and follow-up data were recorded. Complete success was defined as the absence of clinical symptoms, relieved stenosis on imaging, and a stable estimated glomerular filtration rate without serious complications. Results: All surgeries were completed without serious complications. There were eight laparoscopic surgeries and two robotic surgeries. The median length of defect after posteriorly augmented anastomosis was 3 cm (range, 3-5 cm). The median length of the lingual mucosa graft was 4 cm (range, 3-5 cm). The median operative time was 237 minutes (range, 189-310 minutes). The median estimated blood loss was 40 mL (range, 10-100 mL). The median postoperative length of stay was 7.5 days (range, 5-22 days). The Double-J stent was removed median 3.5 months (range, 2-7 months) after the surgery. At the median follow-up of 11 months (range, 7-20 months), all patients achieved the successful criteria of treatment. Conclusion: The posteriorly augmented anastomotic ureteroplasty with lingual mucosal onlay grafts for long proximal ureteral strictures is a feasible and safe technique, which may be an option especially for strictures marginally longer than those that can be safely repaired via end-to-end anastomosis.

Abstract
Despite technical refinements in urologic oncologic surgery, complications are inevitable and often carry significant morbidity. Similar to oncologic surgery, reconstructive surgery has realized a paradigm shift from mainly open to an increasingly minimally invasive approach. Robotic assisted surgery has facilitated this transition as it mitigates some of the limitations of traditional laparoscopy. With continued technological advances in robotic technology along with improved training and experience, the breadth and complexity of cases expand annually. Few head to head trials exist and data is overall heterogeneous. Herein, we review and summarize the currently available literature describing robotic assisted reconstruction for complications following urologic oncologic procedures.

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
PURPOSE To investigate the feasibility of ureteral reconstruction using lingual mucosa graft (LMG) and evaluate the histological changes of the engrafted LMG in beagles. METHODS Twelve male beagle dogs were randomly divided into groups A, B and C (n = 4). A ventral ureteral defect was created by excising half of the ureteral wall. The length of the defect was 3 cm, 6 cm, and 10 cm in groups A, B, and C, respectively. The LMGs were harvested and employed to repair the ureteral defects in onlay fashion. Two dogs per group were sacrificed after 6 months, with additional two dogs per group sacrificed after 12 months. Intravenous urography (IVU) and macroscopic examination were performed to evaluate renal function and ureteral patency. Histological changes in the engrafted LMGs during the tissue incorporation process were assessed by histological analysis. RESULTS There were no postoperative complications. Only one dog in group C developed a mild stricture near the proximal anastomosis. In the remaining 11 animals, IVU showed normal renal function and a wide ureteral caliber without stricture or fistula. The diameter of the LMG-reconstructed ureter was greater than that of the proximal and distal ureter (each p value < 0.01). The LMGs survived in situ with newly formed capillaries. The epithelium of the lingual mucosa resembled the urothelium in postoperative 12 months. CONCLUSION This new technique for ureteral reconstruction using LMGs is feasible. This approach is a promising alternative clinical treatment for curing long ureteral strictures.

A Multi-Institutional Experience With Robotic Ureteroplasty With Buccal Mucosa Graft: An Updated Analysis of Intermediate-Term Outcomes. Urology 2020; 147:306-310. [PMID: 32798516 DOI: 10.1016/j.urology.2020.08.003] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 08/01/2020] [Accepted: 08/03/2020] [Indexed: 01/23/2023]
Abstract
OBJECTIVE To update our prior multi-institutional experience with robotic ureteroplasty with buccal mucosa graft and analyze our intermediate-term outcomes. Although our previous multi-institutional report provided significant insight into the safety and efficacy associated with robotic ureteroplasty with buccal mucosa graft, it was limited by small patient numbers. METHODS We retrospectively reviewed our multi-institutional database to identify all patients who underwent robotic ureteroplasty with buccal mucosa graft between October 2013 and March 2019 with ≥12 months follow up. Indication for surgery was a complex proximal and/or middle ureteral stricture not amenable to primary excision and anastomosis secondary to stricture length or peri-ureteral fibrosis. Surgical success was defined as the absence of obstructive flank pain and ureteral obstruction on functional imaging. RESULTS Of 54 patients, 43 (79.6 %) patients underwent an onlay, and 11 (20.4%) patients underwent an augmented anastomotic robotic ureteroplasty with buccal mucosa graft. Eighteen of 54 (33.3%) patients previously failed a ureteral reconstruction. The median stricture length was 3.0 (IQR 2.0-4.0, range 1-8) centimeters. There were 3 of 54 (5.6%) major postoperative complications. The median length of stay was 1.0 (IQR 1.0-3.0) day. At a median follow-up of 27.5 (IQR 21.3-38.0) months, 47 of 54 (87.0%) cases were surgically successful. Stricture recurrences were diagnosed ≤2 months postoperatively in 3 of 7 (42.9%) patients, and ≥10 months postoperatively in 4 of 7 (57.1%) patients. CONCLUSION Robotic ureteroplasty with buccal mucosa graft is associated with low peri-operative morbidity and excellent intermediate-term outcomes.

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
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
Minimally invasive surgery has made a profound impact on how urologists approach the challenges in reconstruction of the urinary tract. The advent of laparoscopic approaches to reconstructive urology have demonstrated comparable outcomes to open surgery with improved morbidity. The recent adoption of robotic surgery has seen further advancements such as improved visibility and, freedom of movement, and an easier technical learning curve. With these advantages, more reconstructive urology procedures are being performed robotically. Herein, we review reconstructive urology procedures for which robotics have been applied.

Abstract
The diffusion of minimally invasive techniques for renal surgery has prompted a renewed interest in nephropexy which is indicated to prevent nephroptosis in symptomatic patients and to mobilize the upper ureter downward in order to bridge a ureteral defect. Recent publications have been reviewed to present the state of the art of the diagnosis and management of these two challenging conditions and to try to foresee the next steps. The evaluation of patients with mobile kidney can be made relying on diagnostic criteria such as ultrasound with color Doppler and measurement of resistive index, conventional upright X-ray frames after a supine uro-computerized tomography scan and both static and dynamic nuclear medicine scans, always with evaluation in the sitting or erect position. Laparoscopic nephropexy emerges as the current treatment option combining both objectively controlled repositioning of the kidney and resolution of symptoms with minimal invasiveness, low morbidity, and short hospital stay. The use of robotics is presently limited by its higher cost, but may increase in the future. Downward renal mobilization and nephropexy is a safe and versatile technique which has been adopted as a unique strategy or more often in combination with other surgical maneuvers in order to cope with complex ureteral reconstruction.

Abstract
Ureteral stricture resulting from chronic inflammations such as tuberculosis, recurrent stone disease and multiple endourological interventions are complex in nature; these may lead to severe adhesions to surrounding structures. Endourological management of these cases is difficult with poorer outcomes. In such situations, reconstructive surgical corrections remain a reliable option. We describe the technique of onlay and inlay buccal mucosal graft ureteroplasty using a robotic platform in management of complex ureteral strictures.

Abstract
Introduction: Defect in ureteral continuity can be due to various etiologies. The surgical options for management of complex long-segment ureteric defects are limited. Use of ileum is indicated in these cases; however, the technique is challenging and outcomes need to be assessed in detail. Material and Methods: It is an observational study conducted over 4 years. After preoperative optimization, ureteric reconstruction was performed using standard techniques of ileal interposition in cases of unilateral and bilateral long-segment ureteric defects. Patients were followed up at regular interval to assess outcomes and see for complications. Results: A total of 14 patients were studied. Two most common indications for performing ileal ureter were iatrogenic injury and radiation-induced strictures (5–5 cases). Most common site of ureteric involvement was lower and midureter seen in 6 cases. The mean length of the ileum used was 11.2 cm. Mean preoperative nadir creatinine level was 1.57 mg/dL in this study. Average postoperative creatinine level at 4-week follow-up was 1.75 mg/dL and 1.45 mg/dL and 1.37 mg/dL, at 3 and 12 months, respectively. The most common short-term complication was paralytic ileus and long-term complication was recurrent urinary tract infection UTI. There was no mortality. Conclusion: Ileal ureter is found to be relatively easy and safe surgery even in patients with borderline high creatinine. There was no worsening of renal function attributable to the conduit in this study. In patients with limited surgical options, it is a suitable alternative, rather than keeping patient on permanent percutaneous nephrostomy or regular stent change. Metabolic acidosis and mucous-associated complications such as pain, infection, and stone formation can be minimized by adherence to strict protocol.

Abstract
BACKGROUND Minimally invasive treatment of long, multifocal ureteral strictures or failed pyeloplasty is challenging. Robot-assisted buccal mucosa graft ureteroplasty (RBU) is a technique for ureteral reconstruction that avoids the morbidity of bowel interposition or autotransplantation. OBJECTIVE To evaluate outcomes for RBU in a multi-institutional cohort of patients treated for revision ureteropelvic junction obstruction and long or multifocal ureteral stricture at three tertiary referral centers. DESIGN, SETTING, AND PARTICIPANTS This retrospective study involved data for 19 patients treated with RBU at three high-volume centers between October 2013 and July 2016. SURGICAL PROCEDURE RBU was performed using either an onlay graft after incising the stricture or an augmented anastomotic repair in which the ureter was transected and re-anastomosed primarily on one side, and a graft was placed on the other side. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Preoperative, intraoperative, and postoperative variables and outcomes were assessed. A descriptive statistical analysis was performed. RESULTS AND LIMITATIONS The onlay technique was used for 79%, while repair was carried out using the augmented anastomotic technique for the remaining cases. The reconstruction was reinforced with omentum in 95% of cases. The ureteral stricture location was proximal in 74% and mid in 26% of cases. A prior failed ureteral reconstruction was present in 53% of patients. The median stricture length was 4.0cm (range 2.0-8.0), operative time was 200min (range 136-397), estimated blood loss was 95ml (range 25-420), and length of stay was 2 d (range 1-15). There were no intraoperative complications. At median follow-up of 26 mo, the overall success rate was 90%. CONCLUSIONS RBU is a feasible and effective technique for managing complex proximal and mid ureteral strictures. PATIENT SUMMARY We studied robotic surgery for long ureteral strictures using grafts at three referral centers. Our results demonstrate that robotic buccal mucosa graft ureteroplasty is a feasible and effective technique for ureteral reconstruction.

Abstract
OBJECTIVE To demonstrate robot-assisted ureterolysis and buccal mucosal graft (BMG) ureteroplasty for the management of a complex, long recurrent ureteral stricture developing after ureterolysis, and also to demonstrate the use of near-infrared fluorescence (NIRF) imaging and intraoperative ureteroscopy during this procedure. METHODS A 58-year-old man with a history of cabergoline treatment and a cardiac catheterization through the left groin presented with left flank pain and hydronephrosis. A computed tomography scan showed extensive fibrosis around the ureter and a ureteral stricture close to a tortuous left external iliac artery. A computed tomography-guided biopsy showed a benign fibrous tissue around the stricture with no increase in IgG4-expressing plasma cells. A robot-assisted ureterolysis with an omental wrap was performed. One year after the ureterolysis, the patient developed a recurrent ureteral stricture. Retrograde ureterogram showed a long, 6-cm stricture in the upper ureter. For the robotic ureteroplasty, the patient was placed in modified lateral position with port placement similar to the left pyeloplasty. Intraoperative flexible ureteroscopy and NIRF were used to define the distal extent of the stricture. For this, the ureteroscope was advanced until the stricture, and transilluminance of light from the ureteroscope was seen from the robotic camera using Firefly. Ureteral stricture was incised along its length over the ureteroscope. Two BMGs were harvested and sown together to obtain a longer graft. The graft was minimally defatted and brought in the abdomen through one of the ports. The composite graft was then sutured with 4-0 PDS as an onlay graft with the mucosal side facing toward the lumen of the ureter. Ureteroscopy was used to confirm patency, followed by stent placement. NIRF was used to confirm the viability of the ureter and the surrounding tissue. The omental flap was then harvested using a vessel sealer, fixed to the psoas fascia beneath the ureter, and then wrapped over the reconstructed ureter. The omental flap was also tacked to the side of the BMG with a suture to promote blood supply. RESULTS The procedure was uncomplicated with an operative time of 280 minutes, an estimated blood loss of 75 mL, and an uneventful hospital stay. MAG3 Renal scan after 3 and 6 months of surgery showed no recurrence or obstruction. CONCLUSION Despite the limitation of being a single case with only a 6-month follow-up, our report shows that robot-assisted BMG is a safe option for the reconstruction of long upper ureteral strictures. This procedure may be a less morbid alternative to an autotransplant and ileal ureter in these patients. However, outcomes need to be studied in a larger series with a longer follow-up.

Abstract
PURPOSE OF REVIEW This study aimed to provide an overview of the literature on buccal mucosal ureteroplasty for ureteral stricture disease, with a specific focus on the application of the robotic platform to buccal ureteroplasty. RECENT FINDINGS In our review, we highlight the results of Zhao et al. from the New York University School of Medicine Department of Urology, as well as our own results from Temple University Hospital. Zhao et al. published the first series of four patients who underwent robotic buccal ureteroplasty. Mean stricture length was 3.0 cm, and at a mean follow-up of 15 months, all repairs remained patent. We also describe our results in 10 patients who underwent robotic buccal ureteroplasty at Temple University Hospital. Median stricture length was 3.0 cm, and at a median follow-up of 5 months, all repairs remain patent. Robotic buccal ureteroplasty offers a promising option for repair of complex ureteral strictures.

Abstract
OBJECTIVE To assess long-term renal preservation and surgical outcomes in patients undergoing ureteric substitution with ileum. This has been a mainstay of reconstruction options for lengthy ureteral defects. METHODS Consecutive patients aged 18 or older undergoing ileal ureters at our institution were retrospectively reviewed (from 1989 to June 2013). Patients with <6 months of follow-up were excluded. Demographic, surgical, and renal functional outcomes were reviewed. Renal function was assessed by the Chronic Kidney Disease Epidemiology Collaboration and Modification of Diet in Renal Disease Study equations. RESULTS Of the 108 patients meeting the inclusion criteria, 86 (79.6%) had single-renal unit reconstruction and 22 had bilateral reconstruction. Eighty-four (77.8%) had radiation-induced stricture and 24 had iatrogenic or trauma-induced strictures. The median follow-up was 51 months (interquartile range: 22-112). Short-term complications included Clavien grade I (16 [14.8%]), Clavien grade II (3 [2.8%]), Clavien grade III (9 [8.3%]), and Clavien grade IV (3 [2.8%]). Long-term complications included fistula in 6 patients (5.6%), renal failure requiring dialysis in 2 patients (1.9%), hyperchloremic metabolic acidosis in 4 patients (3.7%), and incisional hernia in 11 patients (10.2%). Nine patients (8.3%) had small-bowel obstructions; 3 (2.8%) required adhesiolysis. Four patients (3.7%) had an anastamotic stricture. Nineteen patients (17.6%) had worsening renal function. Cox proportional hazards regression found that those with bilateral repair were at 3.7 times increased risk of worsening renal function (P = .02). CONCLUSION Ureteral substitution with ileum provides an effective and versatile long-term reconstructive option with minimal renal function compromise in properly selected patients. Bilateral reconstruction may contribute to worse long-term renal function.

Abstract
PURPOSE We present our initial experience and 9-month outcomes of the novel technique of laparoscopic onlay lingual mucosal graft ureteroplasty for proximal ureteral stricture. MATERIALS AND METHODS In June 2015, transperitoneal laparoscopic onlay lingual mucosal graft ureteroplasty was performed on a male patient with proximal stricture of the left ureter. The patient complained with left frank pain. Severe hydronephrosis and proximal ureteral dilatation were noted through ultrasonography and CT scan. The length of upper ureteral stricture was 30 mm including 10-mm occlusion. A 46 mm in length and 15 mm in width lingual mucosa graft was harvested from the ventral of the tongue and placed in the strictured ureter as a ventral onlay for laparoscopic ureteroplasty. Operative time, intraoperative, and postoperative complications were well recorded. Follow-up was performed with renal ultrasound, CT scan, and nuclear scan renography as well as clinical assessment of symptoms. RESULTS The new technique was performed successful without intraoperative and postoperative complications. Neither hydronephrosis nor proximal ureteral dilatation in the left side was found through ultrasonography 3, 6, 9 months and CT scan 6 month postoperatively. The left renal function, glomerular filtration rate, had a recovery from 9.6 ml/min preoperatively to 14.0 ml/min at 6-month follow-up, and the patient has no complaints about the donor site and flank pain. CONCLUSIONS To our knowledge, we present the initial experience with laparoscopic onlay lingual mucosal graft ureteroplasty for proximal ureteral stricture. With 9-month outcomes, the new technique appears to be an excellent option for proximal ureteral stricture.

Abstract
Introduction The aim of this study is to demonstrate the results of a case series concerning the replacement of long ureteric strictures using buccal mucosa grafts. Material and methods Five patients (3 men, 2 women), with a mean age of 35 years old, underwent reconstructive ureteral surgery using buccal mucosa graft with omental wrapping during the period of 2010–2013. In all cases, the location of strictures was in the proximal ureters with the length of strictures varying from 2.5 to 5.0 cm. Results We did not observe any major complications postoperatively. Two patients complained of constipation, which was resolved on the second day without any special treatment. Only one patient experienced fever (39°C) on the seventh day after the surgery due to inadequate drainage of the nephrostomic tube. Mean follow-up time was 39.6 months (range 26–52 months), mean hospital stay length was 10.6 days. Intravenous and antegrade urography were performed after removing JJ stents. Results were favorable without any signs of stricture. Repetitive ultrasound and radiologic imaging was performed at month 3, 6, 12 in the first year and every half-year thereafter. Intravenous urography showed no signs of strictures. Hydronephrosis was resolved in all patients by the sixth month following the surgery. Conclusions Postoperatively, we observed favorable results in all patients in terms of absence of short term-surgical complications. This technique could be considered for patients with long ureteric strictures in whom ureteral replacement with bowel interposition or kidney auto-transplantation is contraindicated.

Abstract
Tissue transfer techniques are an essential part of the reconstructive urologist's armamentarium. Flaps and graft techniques are widely used in genital and urethral reconstruction. A graft is tissue that is moved from a donor site to a recipient site without its native blood supply. The main types of grafts used in urology are full thickness grafts, split thickness skin grafts and buccal mucosa grafts. Flaps are transferred from the donor site to the recipient site on a pedicle containing its native blood supply. Flaps can be classified based on blood supply, elevation methods or the method of transfer. The most used flaps in urology include penile, preputial, and scrotal skin. We review the various techniques used in reconstructive urology and the outcomes of these techniques.

Abstract
OBJECTIVE To evaluate the long-term outcomes of robotic-assisted laparoscopic (RAL) upper urinary tract (UUT) reconstruction performed at a tertiary referral centre. MATERIALS AND METHODS Data from 250 consecutive patients undergoing RAL UUT reconstruction, including pyeloplasty with or without stone extraction, ureterolysis, uretero-ureterostomy, ureterocalicostomy, ureteropyelostomy, ureteric reimplantation and buccal mucosa graft ureteroplasty, were collected at a tertiary referral centre between March 2003 and December 2013. The primary outcomes were symptomatic and radiographic improvement of obstruction and complication rate. The mean follow-up was 17.1 months. RESULTS Radiographic and symptomatic success rates ranged from 85% to 100% for each procedure, with a 98% radiographic success rate and 97% symptomatic success rate for the entire series. There were a total of 34 complications, none greater than Clavien grade 3. CONCLUSION Robotic-assisted laparoscopic UUT can be performed with few complications, with durable long-term success, and is a reasonable alternative to the open procedure in experienced robotic surgeons.

Abstract
Open surgical reconstruction of the ureter is a urological procedure with a potentially high risk of complications. The correct selection of patients and time of operation are important aspects regarding the treatment strategy. Position and length of the affected ureter segment to be reconstructed determine the surgical intervention possibilities. The psoas hitch procedure is a well-established technique for distal reconstruction of the ureter where most iatrogenic injuries occur. In more proximal or complex defects, several procedures are available. Partial or complete replacement of the ureter with bowel is still considered the standard for bridging long ureteral defects but is accompanied with higher intra- and postoperative complication rates. In specific patients and situations, autotransplantation of the kidney and subcutaneous pyelovesical bypasses are clinical options. Using mucosal grafts or tissue engineering may be new therapeutic prospects to cover ureteral defects but the clinical impact still needs to be clarified. All therapeutic strategies share the fact that great surgical expertise and experience are necessary as the operative technique must be mastered to avoid severe complications.
