[PMID: 38369201 DOI: 10.1016/j.urology.2024.01.020] [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: 12/03/2023] [Revised: 01/06/2024] [Accepted: 01/25/2024] [Indexed: 02/20/2024]
Abstract
OBJECTIVE To describe our institution's experience with Boari flap ureteral reconstruction, specifically focusing on the development of postoperative lower urinary tract symptoms (LUTS). METHODS A retrospective review of all Boari flaps performed at our institution between 2013 and 2023 was performed, excluding patients with urothelial carcinoma and males, given the frequency of LUTS from benign prostatic hyperplasia. Primary outcome was the development of new onset LUTS and subsequent treatment. Secondary outcomes included postoperative infections and ureteral stricture. RESULTS Twenty-nine total patients were identified. Mean age was 52.2 years (standard deviation (SD) 13.1). Mean follow-up was 22.3 months (SD 25.3). Primary reasons for ureteral reconstruction were radiation damage (37.9%) and iatrogenic surgical injury (37.9%). A concurrent psoas hitch was performed in 18/29 (62%) cases, nephropexy was utilized in 1/29 (3.4%) cases, and contralateral bladder pedicles were ligated in 10/29 (34.5%) for increased bladder mobilization. Postoperatively, 8 patients (27.6%) developed new-onset LUTS, effectively managed with oral anticholinergics. Recurrent urinary tract infections occurred in 5 patients (17.2%) and pyelonephritis in 1 (3.4%) patient. Two patients (6.9%) developed ureteral strictures, one treated with ileal ureter replacement and the other with ureteral balloon dilation. CONCLUSION Boari bladder flap ureteral reconstruction leads to moderate rates of new onset LUTS postoperatively, which is important information when counseling women on reconstructive options. Boari flap ureteral reconstruction has a high success rate, and serious complications are rare. In the setting of ureteral injury, reconstruction using Boari flaps with or without psoas hitch should be considered for definitive management.

Robotic-assisted vs. open ureteral reimplantation: a multicentre comparison. World J Urol 2024; 42:194. [PMID: 38530438 DOI: 10.1007/s00345-024-04875-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 02/09/2024] [Indexed: 03/28/2024] Open
Abstract
PURPOSE Open ureteral reimplantation is considered the standard surgical approach to treat distal ureteral strictures or injuries. These procedures are increasingly performed in a minimally invasive and robotic-assisted manner. Notably, no series comparing perioperative outcomes and safety of the open vs. robotic approach are available so far. METHODS In this retrospective multi-center study, we compared data from 51 robotic ureteral reimplantations (RUR) with 79 open ureteral reimplantations (OUR). Both cohorts were comparatively assessed using different baseline characteristics and perioperative outcomes. Moreover, a multivariate logistic regression for independent predictors was performed. RESULTS Surgery time, length of hospital stay and dwell time of bladder catheter were shorter in the robotic cohort, whereas estimated blood loss, postoperative blood transfusion rate and postoperative complications were lower than in the open cohort. In the multivariate linear regression analysis, robotic approach was an independent predictor for a shorter operation time (coefficient - 0.254, 95% confidence interval [CI] - 0.342 to - 0.166; p < 0.001), a lower estimated blood loss (coefficient - 0.390, 95% CI - 0.549 to - 0.231, p < 0.001) and a shorter length of hospital stay (coefficient - 0.455, 95% CI - 0.552 to - 0.358, p < 0.001). Moreover, robotic surgery was an independent predictor for a shorter dwell time of bladder catheter (coefficient - 0.210, 95% CI - 0.278 to - 0.142, p < 0.001). CONCLUSION RUR represents a safe alternative to OUR, with a shorter operative time, decreased blood loss and length of hospital stay. Prospective research are needed to further define the extent of the advantages of the robotic approach over open surgery.

[PMID: 38263443 PMCID: PMC10805737 DOI: 10.1038/s41598-024-52497-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Accepted: 01/19/2024] [Indexed: 01/25/2024] Open
Abstract
To present our experience with laparoscopic ureteroneocystostomy with bladder flap (LUCBF) for treating benign ureteral stenosis and evaluate its feasibility and efficacy. The clinical data of 27 patients with benign ureteral stenosis who underwent LUCBF were retrospectively analyzed. After identification and excision of the ureteral stenosis segment, the healthy ureteral stump was dissected and incised longitudinally. A U-shaped or spiral bladder flap was harvested from the anterolateral bladder wall for ureteroplasty. All patients underwent LUCBF successfully, including 14 patients were combined with psoas hitch technique, between 90 and 220 min (median, 155 min). The median length of ureteral defect was 6 cm (range, 5-17 cm). The median blood loss was 40 ml (20-150 ml). The median indwelling time of double-J stent was 8 weeks (range, 4-8 weeks). Five patients (10.6%) suffered postoperative complications during the follow-up period (range, 12-48 months), including fever, hematuria, urinary tract infection and recurrent stenosis. The success rate was 96.3% (26/27). Patients with long ureter defects had longer operative time and more blood loss than short ureter defects. LUCBF was a safe and feasible technique for benign ureteral stenosis. Long ureter defect was related to longer operative time and more blood loss.

Abstract
BACKGROUND The KangDuo-Surgical Robot-01 (KD-SR-01) system is a new surgical robot recently developed in China. The aim of this study was to present our single-center experience and mid-term outcomes of urological procedures using the KD-SR-01 system. METHODS From August 2020 to April 2023, consecutive urologic procedures were performed at Peking University First Hospital using the KD-SR-01 system. The clinical features, perioperative data, and follow-up outcomes were prospectively collected and analyzed. RESULTS A total of 110 consecutive patients were recruited. Among these patients, 28 underwent partial nephrectomy (PN), 41 underwent urinary tract reconstruction (26 underwent pyeloplasty, 3 underwent ureteral reconstruction and 12 underwent ureterovesical reimplantation [UR]), and 41 underwent radical prostatectomy (RP). The median operative time for PN was 112.5 min, 157.0 min for pyeloplasty, 151.0 min for ureteral reconstruction, 142.5 min for UR, and 138.0 min for RP. The median intraoperative blood loss was 10 mL for PN, 10 mL for pyeloplasty, 30 mL for ureteral reconstruction, 20 mL for UR, and 50 mL for RP. All procedures were successfully completed without conversion, and there were no major complications in any patient. The median warm ischemia time of PN was 17.3 min, and positive surgical margin was not noted in any patient. The overall positive surgical margin rate of RP was 39% (16/41), and no biochemical recurrence was observed in any RP patient during the median follow-up of 11.0 months. The surgical success rates of pyeloplasty and UR were 96% (25/26) and 92% (11/12) during the median follow-up of 29.5 months and 11.5 months, respectively. CONCLUSION The KD-SR-01 system appears feasible, safe, and effective for most urological procedures, based on our single-center experience.

[PMID: 37828505 PMCID: PMC10571348 DOI: 10.1186/s12894-023-01313-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2022] [Accepted: 08/29/2023] [Indexed: 10/14/2023] Open
Abstract
INTRODUCTION Robotic ureteral reconstruction (RUR) has been widely used to treat ureteral diseases. To summarize the surgical techniques, complications, and outcomes following RUR, as well as to compare data on RUR with open and laparoscopic ureteral reconstruction. METHODS Our systematic review was registered on the PROSPERO (CRD42022309364) database. The PubMed, Cochrane and Embase databases were searched for publications in English on 06-Feb-2022. Randomised-controlled trials (RCTs) or non-randomised cohort studies with sample size ≥ 10 cases were included. RESULTS A total of 23 studies were included involving 996 patients and 1004 ureters from 13 non-comparative, and 10 retrospective comparative studies. No RCT study of RUR was reported. The success rate was reported ≥ 90% in 15 studies. Four studies reported 85-90% success rate. Meta-analyses for comparative studies showed that RUR had significantly lower estimated blood loss (EBL) (P = 0.006) and shorter length of stay (LOS) (P < 0.001) than the open approach. RUR had shorter operative time than laparoscopic surgery (P < 0.001). CONCLUSIONS RUR is associated with lower EBL and shorter LOS than the open approach, and shorter operative time than the laparoscopic approach for the treatment of benign ureteral strictures. However, further studies and more evidence are needed to determine whether RUR is more superior.

Abstract
To compare the efficacy and safety between open ureteral replantation (OUR), laparoscopic ureteral replantation (LUR) and robot-assisted laparoscopic ureteral replantation (RALUR). This review produced by the R3.5.0 software with "gemtc" program package and JAGS3.4.0 software based on the Bayesian model. A comprehensive search was done in databases including PubMed, Web of Science, Embase, Cochrane library, Cnki, CBM and WANFANG DATA. Studies that compared OUR, LUR OR RALUR were selected. Summary of Conclusions by ranking of Outcomes. A total of 3949 patients from 29 studies were included. The success rate in OUR, LUR and RALUR was 97.72%, 94.68% and 95.82%. The OR (95% CI) of LUR and RALUR was 0.76 (0.42,1.7) and 0.76 (0.30, 2.6), respectively, compared with OUR. The rate of complications in OUR, LUR and RALUR was 12.78%, 7.94% and 16.32%. The OR (95% CI) of LUR and RALUR was 0.28 (0.16, 0.48) and 0.61 (0.24,1.3), respectively, compared with OUR. The MD (95% CI) of LUR and RALUR for operation time was 22 (2,40) and 46 (7.5,84), respectively, compared with OUR. The MD (95% CI) of LUR and RALUR for hospital stay was - 3.6 (- 4.5, - 2.7) and - 1.1 (- 2.9, 0.58), respectively, compared with OUR. There is no significant difference in the success rates of OUR, LUR, and RALUR. RALUR and OUR has similar complication rates and time of hospital stay, while LUR has fewer complications and faster time to discharge compared to RALUR and OUR. The operative time of OUR is significantly less compared to LUR and RALUR.

Int Urol Nephrol 2022; 54:1865-1870. [PMID: 35594006 DOI: 10.1007/s11255-022-03224-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Accepted: 03/24/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND This study was designed to evaluate the feasibility of laparoscopic ureteral reimplantation with a Boari flap for long-segment ureteric avulsion or ureteric strictures of the middle and lower ureters. By observing its curative effect and prognosis, we can provide a safer and reliable treatment option for patients with middle and lower ureteral injury. METHODS In this study, of the eight cases under study, five were diagnosed with long-segment ureteric strictures, one had long-segment ureteric avulsion, one was diagnosed with ureteral rupture caused by surgical injury of appendicitis, and the remaining one underwent ureterostomy after ureteral injury. The location of ureteral injury was in the middle lower segment. All eight patients underwent laparoscopic ureteral reimplantation with a Boari flap from January 2018 to October 2021. In this study, two patients were treated with a Boari bladder flap with psoas hitching. All procedures were performed by the same surgeon with over 20 years of experience in urological surgery. RESULTS The mean length of ureteric avulsion or ureteric strictures was 7.94 cm (range, 4-15 cm). Laparoscopic ureteral reimplantation with a Boari flap was performed successfully between 120 and 240 min. The mean duration of postoperative hospital stay was 6 days, and no major complications related to the procedure in the perioperative period occurred. Postoperative follow-up showed no obvious hydronephrosis on computed tomography urography or urinary ultrasound in all eight patients. Postoperative reexamination did not reveal any significant hydronephrosis, urinary tract infection, or ureteral reflux, and none of the postoperative renal functions were abnormal. CONCLUSIONS Laparoscopic ureteral reimplantation with a Boari flap is safe and feasible for experienced physicians. In our case, the length/width ratio of bladder flap is more than 4:1, with good blood supply and no obvious complications, it provides a longer alternative length.

Abstract
Background To develop an original and standardized ureteral stricture disease (USD) score and classification system for quantifying ureter stricture characteristics, assessing complexity of the minimally invasive upper urinary tract reconstructive (UUTR) surgical procedure, formulating preoperative plans, and offering objective comparisons of surgical techniques between different institutions and surgeons. Methods We retrospectively reviewed a test set of 64 patients and a validation set of 170 patients who underwent minimally invasive UUTR surgery from January 2018 to January 2021. Three factors were selected to be included in the USD score and classification system: (I) stricture etiology (E, 1–2 points); (II) stricture segment (S, 0–3 points); and (III) length of stricture (L, 1–5 points). The UUTR surgery involves low-complex surgeries (cystoscopy with ureteral dilation and stent placement, ureteropyeloplasty, end to end repair, ureteral reimplantation) and high-complex surgeries (onlay repair (buccal mucosae, lingual mucosae, appendix mucosae), Boari flap repair and ileal ureter replacement). Estimated blood loss and operative time were used as surrogate indicators of surgical complexity. Results The interrater reliability of the USD score and classification system was 0.908. A linear relationship between the USD score and estimated blood loss was observed (rs =0.676, P<0.001). The USD score was also correlated with operative time (rs =0.638, P<0.001). A significant difference in USD scores was found between the high and low complexity surgery groups (4 vs. 7, P<0.001). Variability of UUTR surgery is based on USD classification system, but with regularity to conform to. Conclusions The USD score and classification system is a concise, easily applicable, and validated scale to delineate the clinically significant features of ureter stricture that correlate with the complexity of the UUTR surgical procedure. The use of this score and classification system can facilitate preoperative plan and comparison of USD treatments in clinical practice and urological literature. Research with large sample is needed to further examine and modify the use of the system.
