Abstract

Introduction: To improve the outcomes and extend the adaptation of salvage surgery for intractable urinary tract problems, this study retrospectively investigated indications and outcomes of retroperitoneal surgery based on retroperitoneal laparoscopic ureterolysis (RLU), in which the ureter is dissected with or without nephrolysis. Patients and Methods: Twenty-three salvage surgeries based on RLU were performed on 22 patients at our hospital between November 2002 and July 2017. Intractable urinary tract problems included lower urinary tract dysfunctions, refractory urinary fistulas, middle or lower ureter troubles, ureteroileal anastomotic strictures, and stomal stricture of cutaneous ureterostomy. After RLU, various urinary tract reconstructions were performed through minimal laparotomy under a retroperitoneal approach. Results: In all patients, RLU secured a sufficient length of ureter for subsequent urinary tract reconstructions, irrespective of intra-abdominal adhesions. Twelve cutaneous ureterostomies, one reconstruction of cutaneous ureterostomy, two ureteroileal reanastomoses, and five ureterovesicostomies were effectively performed after unilateral RLU. Three retroperitoneoscopic transureteroureterostomies with cutaneous ureterostomy were reconstructed after bilateral RLU. Over a median follow-up of 8 months (interquartile range, 2-80 months), two patients (8.7%) required additional procedures. Conclusions: Retroperitoneal salvage surgery based on RLU appears useful to salvage intractable urinary tract problems, avoiding intra-abdominal adhesions and securing a sufficient ureteral length for subsequent urinary tract reconstructions. This surgical procedure is minimally invasive and contributes to improving patient quality of life.
