Robot-assisted laparoscopic cystectomy with non-continent urinary diversion for neurogenic lower urinary tract dysfunction: Midterm outcomes.

OBJECTIVES: The aim of this study was to assess midterm functional outcomes and complications of robot-assisted laparoscopic cystectomy with non-continent urinary diversion in patients with neurogenic lower urinary tract dysfunction. MATERIALS AND METHODS: We performed a retrospective single center study including all patients who underwent robot-assisted laparoscopic cystectomy with non-continent urinary diversion between January 2008 and December 2018 for neurogenic lower urinary tract dysfunction. Perioperative data, early and late complications, reoperation rate, renal function, and patient satisfaction (PGI-I) were evaluated. RESULTS: One hundred and forty patients were included (70 multiple sclerosis, 37 spinal cord injuries, 33 others) with a median follow-up of 29 months (12-49). The main indication for surgery was an inability to perform intermittent self-catheterization (n = 125, 89%). The early complication rate (<30 days) was 41% (n = 58), including 72% (n = 45) minor complications (Clavien I-II) and 29% (n = 17) major complications (Clavien III-V). Three patients died in the early postoperative period. Late complications appear in 41% (n = 57), with 9% (n = 13) being ureteroileal anastomotic stricture. The overall reintervention rate was 19% (n = 27), mainly for lithiasis surgery. Pre- and postoperative renal function were comparable. Most of patients reported an improvement in their quality of life following their surgery (PGI-I 1-2). CONCLUSION: Robot-assisted laparoscopic cystectomy with non-continent urinary diversion may be of particular interest in patients with neurogenic lower urinary tract dysfunction who are unable to benefit from conservative treatment, as it provides midterm protection of the upper urinary tract and an improvement in quality of life.

Right Kidney Mini-Invasive Living Donor Nephrectomy: A Safe and Efficient Alternative.

INTRODUCTION: Right kidney living donor transplantation is considered more difficult and associated with more complications. The objective was to evaluate donor safety and graft function of right hand-assisted laparoscopic donor nephrectomy (HALDN). METHODS: A total of 270 consecutive HALDN procedures have been performed in our institution up to April 2017. We retrospectively compared the outcomes of right-sided nephrectomy (R-HALDN) to left-sided nephrectomy (L-HALDN) to evaluate donor safety and graft function of R-HALDN. RESULTS: Sixty-seven right kidneys were removed for functional asymmetry in favour of left kidney (35/67) or left kidney multiple arteries (28/67). Among the donors, neither conversion to open surgery nor preoperative blood transfusion was necessary. There was no significant difference in operative time, compared to L-HALDN group (170 ± 37 min vs. 171 ± 32 min; p value = 0.182). Warm ischaemia time was significantly longer for R-HALDN (4.0 ± 1.6 min vs. 3.0 ± 1.7 min; p < 0.001). There was no significant difference in terms of post-operative complications and serum Cr levels. Among the recipients, there were no graft venous thrombosis. There was no significant difference in delayed graft function (3 for R-HALDN group and 8 for L-HALDN group; p value = 0.847), serum Cr levels, and graft survival. CONCLUSION: R-HALDN is a safe procedure for kidney donors, with excellent graft function for the recipients, compared to L-HALDN.

Living-donor kidney transplantation: comparison of sequential and simultaneous surgical organizations.

PURPOSE: The objective of this study was to compare living-donor kidney transplantation (LDKT) performed either sequentially, in one operating room, leading to extended cold ischemia time (CIT) or simultaneously, in two different operating room, with shorter CIT. METHODS: We retrospectively included all living-donor nephrectomies and kidney transplantations, performed from March 2010 to March 2014, in three French university centers. In the first one (C1), LDKTs were performed in sequential manner (Sequential group) and in C2 and C3, LDKTs were performed in simultaneous manner (Simultaneous group). RESULTS: A total of 324 LDKT were performed: 176 LDKT in Sequential group and 148 LDKT in Simultaneous group. Patients characteristics were equivalent between groups, except nephrectomy side, ABO mismatch rate and previous kidney transplantation rate. CIT, rewarming time, transfusion and delayed graft function (DGF) were significantly higher in Sequential group. Overall survival and graft survival of kidney transplant recipients were similar in the Sequential and Simultaneous groups. 5-year eGFR was similar between groups. In univariate analysis, number of graft arteries, recipient BMI, previous kidney transplantation status and CIT were significant predictors of DGF. Only previous kidney transplantation status was an independent predictive factor of DGF in the multivariate analysis. CONCLUSIONS: Sequential surgical organization results in the same functional results as simultaneous surgical organization. DGF was higher for LDKT performed sequentially but at 5-year overall survival, graft survival and eGFR were similar between these two types of transplant organizations.

Long-term Outcome of Renal Transplantation in Patients with Congenital Lower Urinary Tract Malformations: A Multicenter Study.

BACKGROUND: Renal insufficiency can occur in patients with congenital lower urinary tract malformations (LUTM) even when managed during infancy. Data in the current literature concerning this subject remain sparse. The aim of this study was to report the feasibility and long-term results of renal transplantation during adulthood in patients with a congenital LUTM. METHODS: A retrospective multicenter study from 3 French renal transplant centers was conducted, including 123 transplantations on 112 patients with LUTM (1996-2016). Graft survival, patient survival, and complications were analyzed. Results were stratified according to the underlying uropathy and the type of initial management during childhood or before transplantation. RESULTS: In this study, patients suffering from posterior urethral valves (n = 49), spina bifida (n = 21), central neurogenic bladder (n = 13), bladder exstrophy (n = 14), prune belly syndrome (n = 12), Hinman syndrome (n = 6), urogenital sinus (n = 4), and other pathologies (n = 4) were included. The mean age at transplantation was 32.1 years old (±11.2). The mean follow-up period was 7.2 years. Patient survival at 1, 5, 10, and 15 years was 97.4%, 93.0%, 89.4%, and 80.0%, respectively. Graft survival at 1, 5, 10, 15, and 20 years was 96.6%, 87.6%, 77.3%, 60.6%, and 36.4%, respectively. Enterocystoplasty and continent urinary diversions exposed grafts to more frequent acute pyelonephritis (P = 0.02). There was no difference in graft survival when transplantation was performed on an enterocystoplasty or urinary diversions compared with a native bladder, provided a well-conducted bladder management. CONCLUSIONS: Even though enterocystoplasty and continent urinary diversions exposed grafts to more frequent acute graft pyelonephritis, patient and graft survival rates in LUTM at 10 years were similar to other kidney transplantations on native bladders.
