Is night-time surgical procedure for renal graft at higher risk than during the day? A single center study cohort of 179 patients.

INTRODUCTION: Various surgical centers tend to postpone a kidney transplantation (KT) to the following morning than to operate at night-time. The objective of our study was to assess whether there was any difference between daytime and night-time renal transplantation in our institution. METHOD: This study is a retrospective monocentric study including all the KTs that were performed between 2012 and 2013 by transplant expert surgeons in our institution. Clavien-Dindo (CD) complications were classified according to 7 variables going from 1 to 5. Time before postgraft diuresis and delayed graft function (DGF) were also analyzed. Two groups of patients were formed according to threshold value of incision time (6.30 p.m.). Data comparison were performed using the Kruskal-Wallis nonparametric test. RESULTS: A total of 179 patients were included. Median follow-up was 24 months. Cold ischemia time was longer in the night-time transplantation (1082 vs. 807 min, p < .001), but rewarming time was shorter (47.24 vs. 52.15 min, p = .628). No statistically significant differences were observed between the two groups using the Kruskal-Wallis method for CD complications (Qobs: 0.076; p = .735). CD complications proportion was similar, with a majority of grade II complications (72.7% daytime group vs. 75.4% night-time group (p = .735). DGF (19 patients for daytime group vs. 13 patients for night-time group, p = .359) and time before postgraft diuresis (4.65 days daytime group vs. 5.27 days night-time group, p = .422) were similar between both groups. Multivariate analysis did not show significant predictors of CD complications Grade 3 and more. CONCLUSION: Night-time renal transplantation did not induce more postoperative CD complications than diurnal procedures in our cohort, challenging the false preconceptions that allow surgical teams to delay this surgery.

Does Prostate Median Lobe Really Matter for GreenLight HPS Laser Photovaporization of the Prostate.

Background: Benign prostatic hyperplasia (BPH) is a common pathology in elderly patients, inducing lower urinary tract symptoms. The treatment of BPH is first a medical option, then a surgical treatment, either by endoscopy or open surgery. We here report a case of GreenLight HPS™ laser photovaporization (PV) with an impaired maintenance of median lobe postoperatively, unimportant on functional results. Case Presentation: A 68-year-old man presented with lower urinary tract symptoms in the last 2 years, treated first by medicine with good response. On digital rectal examination, the enlarged prostate was homogeneous and regular. International Prostate Symptom Score (IPSS) was 30/35, Incontinence Quality of Life (iQol) 6/6, and International Index of Erectile Function 5 14/25 with regular sexual activity. Transrectal ultrasound (TRUS) reported BPH of 62 g with a median lobe of 6 g protruding into the bladder. At uroflowmetry, maximum urinary flow rate (Qmax) was 8 mL/s for 90 cc void volume and 20 cc postvoid residual. After failure of medical treatment, we offered a surgical treatment option by laser therapy using the 180W XPS GreenLight™. At 1-month follow-up, functional outcomes were improved with a Qmax of 11 mL/s, postvoiding residual volume 0 cc, IPSS 12/35, and iQol 2/6. At 3-month follow-up, outcomes still improved, although the TRUS reported a prostate volume of 30 g with a persistent median lobe. Conclusion: Impaired maintenance of median lobe after GreenLight laser PV does not seem to affect functional results. This case report opens the way for a new therapeutic strategy for patients according to their prostate anatomy. A randomized clinical trial could be done about surgical treatment for patient BPH according to prostate volume and anatomy.

Endoureteral Management of Renal Graft Ureteral Stenosis by the Use of Long-Term Metal Stent: An Appealing Treatment Option.

Background: Ureteral stenosis is part of the common complications of renal graft reported in 3% to 7% of cases. Multiple treatments have been introduced regarding length and position of the stenosis. Metal stents for urologic purpose were created in 1998. Double percutaneous antegrade and transurethral retrograde access to a ureteral stenosis to a long-term metal stent procedure has been rarely described. Case Presentation: Here, we present a case of a ureteral stricture in a double ipsilateral kidney graft with a common ureter. A 67-year-old patient presented with obstructive nephritis associated with acute renal failure 6 years after a double renal graft with a uretero-ureteral end-to-side anastomosis. Abdominal CT scan showed double pelvic dilation. The patient underwent double percutaneous nephrostomies and antegrade pyelogram showed both renal pelvic and ureter dilations caused by a severe chronic ureteral stenosis at junction into the bladder. A Double-J ureteric stent was then inserted retrogradely over a guidewire as first-line treatment. Due to recurrent urinary tract infections (UTIs), removal and replacement of Double-J stents were carried out by placing a thermoexpandable metal stent Memokath® 051 (Bard, Pnn Medical) through the common ureter by a double antegrade and retrograde approach. Treatment was effective with a good renal function maintained after a 3-year follow-up without UTIs. Conclusion: Double antegrade and retrograde access to a long-term metal stent treatment can be seen as an alternative treatment to either endoscopy or open surgery. Further studies should be continued using larger series.
