Hand-Assisted Laparoscopic Native Nephrectomy for Polycystic Kidney Disease Before Transplantation: A Single-Centre Case Series with a Technique-Stratified Focused Scoping Review

Background: Native nephrectomy is frequently required in autosomal-dominant polycystic kidney disease (ADPKD) before or during transplantation, but the optimal minimally invasive approach is unsettled, and it is unclear whether the pattern of post-operative complications tracks with operative technique. We report a retrospective single-centre experience of hand-assisted laparoscopic (HAL) native nephrectomy and, alongside it, a technique-stratified scoping review of complications. Methods: We retrospectively reviewed all consecutive adults undergoing HAL native nephrectomy—with an infra-umbilical midline hand-port and free intraperitoneal cyst rupture—in preparation for transplantation in the period between December 2019 and December 2025. In parallel, we performed a PRISMA-ScR-compliant scoping review (MEDLINE, Embase, Scopus) of minimally invasive ADPKD nephrectomy, with duplicate independent screening and extraction, stratifying complications by operative approach and cyst-decompression method. No quantitative pooling was undertaken. Results: Twenty-three patients (mean age 52.8 ± 9.9 years; 87% dialysis-dependent; 78% for transplant preparation) were included. Median operative time was 102 min (IQR 90–122) with minimal blood loss, one transfusion (4%), and no open conversion. Complications occurred in 8/23 (35%) and were bowel-predominant: one small-bowel perforation, two obstructions, and one ileus—three of Clavien–Dindo grade IIIb, all in right-sided nephrectomies and independent of specimen weight. Peri-operative mortality was 1/23 (4%), from a non-technique-related mycotic aortic dissection. Of 481 records screened, 19 studies met inclusion; the cyst-decompression method was reported in only 7 (37%). Bowel events clustered in series using free intraperitoneal cyst rupture or puncture and were largely absent where decompression was contained, a pattern crossing platform boundaries and that is mechanistically consistent with intraperitoneal spillage of cyst contents. Conclusions: HAL native nephrectomy is a rapid and feasible means of removing massively enlarged polycystic kidneys before transplantation but, in our experience, carries a bowel-predominant morbidity that clustered in right-sided procedures and was independent of specimen weight. The sparse literature is consistent with—but cannot confirm—a relationship to intraperitoneal cyst spillage rather than to the hand-assisted approach itself. Whether contained cyst decompression can preserve operative efficiency while reducing bowel morbidity is a hypothesis warranting prospective study.
