Laparo-Endoscopic Single-Site Left Donor Nephrectomy In Patients With Uncommon Renal Vascular Anatomy: Does the Technique Make a Difference?

BACKGROUND: To compare donor and recipient outcomes in patients with renal artery and ante-aortic renal vein vs unusual renal vascular anatomy undergoing laparoendoscopic single-site donor nephrectomy (LESSDN). METHODS: A retrospective chart review of the comparative study of donor and recipient outcomes of LESSDN in donors with venous abnormality (n = 28, group A), arterial abnormality (n = 74, group B), and standard donors (n = 248, group C). RESULTS: From September 2016 to August 2022, 350 left LESSDN were performed. The most common anomalies in group A were the retro-aortic and 2 renal veins in 12 patients each. In group B, 72 and 2 patients had 2 and 3 renal arteries, respectively. Operative and warm ischemia times were significantly longer in donors with vascular anomalies. Moreover, patient creatinine on discharge was significantly higher in arterial anomalies; it was 1.61 ± 0.22 compared with 1.26 ± 0.43 and 1.25 ± 0.32 mg/dL for patients with no anomalies and venous anomalies, respectively (P < .001). However, serum creatinine levels recovered after 1 month and were comparable between the study groups. Recipients, operative time, and vascular anastomosis time were significantly longer in recipients with vascular anomaly. Slow graft function was higher in group B (6.9%) than in the other groups. One-year graft survival rates were 96.4%, 94.6%, and 97.1% (P = .496). CONCLUSION: With increased experience, LESSDN in multiple renal arteries and uncommon venous anatomy cases is feasible and safe. Moreover, it does not influence donor or recipient outcomes.

Does Kidney Transplantation Help Young Patients on Dialysis With Erectile Dysfunction? A Single-center Study.

OBJECTIVE: to investigate the effects of a successful KT on EF in male patients with ESRD. MATERIALS AND METHODS: A single-center cross-sectional prospective study to assess the erectile dysfunction in male patients one month before and one year after KT. We adopted a validated, self-administered translated International Index of Erectile Function (IIEF-15) questionnaire. A sub-analysis was performed by categorizing the cohort into 2 age groups: <50 and ≥50 yr. RESULTS: Between September 2017 and February 2021, 68 ESRD patients underwent kidney transplantation (KT), with a mean age of 48.9 ± 12.9 years. Thirty-one patients were below 50 years (Group I). The median hemodialysis duration was 12 months. Sixty-three patients (92.6%) had ED. The mean total IIEF-15 score before and after was 46.8/75 ±12.7 and 55.5 ±13, respectively (P <.001). Forty-six patients (67.6%) reported improved erectile function, 22 (32.4%) did not demonstrate any change, and no patient reported deterioration. Moreover, after KT, sexual desire, orgasm, and overall patient satisfaction improved significantly. Before KT, 83.8% and 100% of groups I and II patients had ED, which dropped to 22.6% and 86.5%, respectively, after KT. IIEF-15 scores improved in both groups. However, the improvement in ED was observed significantly in young patients with mild ED. CONCLUSION: KT positively impacts sexual function and improves erectile dysfunction, especially among young patients. The duration of dialysis before kidney transplantation had no impact on ED improvement after transplantation. The positive effect of transplantation on ED could encourage ESRD patients to undergo KT.

Successful Endovascular Repair of Infectious External Iliac Artery Anastomotic Pseudoaneurysm With Graft Preservation Post-Kidney Transplantation: Case Report and Review of Literature.

BACKGROUND: Allograft artery-infected pseudoaneurysm (PA) represents a rare but life-threatening complication of kidney transplantation (KT). A review of the literature, showed that nearly all these cases ended resulted in graft loss. We presented a case of post-KT-infected external iliac artery anastomotic PA successfully managed by endovascular stenting with graft preservation. Additionally, we reviewed the pertinent literature. METHOD: In this article, we described a hypertensive, 47-year-old man who presented 1 month post-cadaveric KT with acute kidney injury and gram-negative bacteremia secondary to a large infectious anastomotic PA of the external iliac artery. RESULTS: Because of favorable anatomy, successful arterial angio-stent fixation of the main renal artery PA, sparing the lower polar artery, was performed after 1 week of antibiotic and fungal coverage. CONCLUSION: Patient was discharged after 2 weeks with functioning graft. Graft function was stable after 3 months.
