Purpose:
To describe a novel single-position intraperitoneal laparoscopic surgery (SP-ILS) technique for radical nephroureterectomy (RNU) and bladder cuff excision (BCE) in the supine position.
Methods:
Between January 2019 and June 2023, 40 patients with UTUC underwent laparoscopic RNU and BCE using the SP-ILS technique. Clinical, perioperative, and pathological data were retrospectively analyzed.
Results:
All procedures were performed laparoscopically without patient repositioning. No intraoperative or postoperative complications occurred. The mean operative time was 101.0 ± 24.5 minutes, and mean estimated blood loss was 53 ± 27.0 mL. The median postoperative hospital stay was 4.2 ± 1.1 days. Postoperative pathology revealed Ta in 14 patients, T1 in 21 patients, and T2 in 5 patients. During a mean follow-up of 12.9 months (range, 2-24), one patient developed bladder recurrence.
Conclusions:
The SP-ILS technique offers direct visualization, reproducible bladder cuff excision, and efficient single-position workflow during both LRNU and BCE.
