Purpose: To present the oncologic and functional outcomes of robot-assisted partial nephrectomy (RAPN) and analyze retroperitoneal and transperitoneal approaches.
Patients And Methods: RAPN was performed on 103 patients; 44 patients underwent a retroperitoneal and 59 a transperitoneal approach. Demographic, operative, and postoperative data was collected and retrospectively analyzed on all patients.
Results: Overall average warm ischemic time was 20.4 (0-48) minutes, total operative time was 175.3 (85-330) minutes, and estimated blood loss was 258.1 (20-3100) mL. When retroperitoneal and transperitoneal approaches were compared, there was no significant difference in warm ischemic time but a significant reduction in both estimated blood loss and total operative time in the retroperitoneal group.
Conclusion: Our series would suggest that if performed by a surgeon familiar with a laparoscopic retroperitoneal approach to renal surgery, retroperitoneal RAPN is at least equivalent to the more common transperitoneal approach in the outcomes assessed.

Randomised controlled feasibility trial of retroperitoneal vs transperitoneal robot-assisted partial nephrectomy: the ROPARN study.
BJU Int

Department of Urology, St. Josef Medical Center, University of Regensburg, Regensburg, Germany.
Objectives: To assess the feasibility of trial recruitment and confirm that retroperitoneal robotic partial nephrectomy (RRPN) has the same oncological efficacy as transperitoneal robotic partial nephrectomy (TRPN), with time advantages and less peri-operative morbidity, in a randomised controlled trial (RCT).
Patients And Methods: The study was designed as a single-centre, open-label, feasibility RCT. Patients with suspected localised renal cell carcinoma referred for robotic partial nephrectomy were randomised in a 1:1 ratio to receive either TRPN or RRPN.

Purpose: To evaluate the predictors of delayed discharge for patients undergoing robot-assisted partial nephrectomy (RAPN) at our Institution since the introduction of the single port (SP) robotic system.
Methods: We performed a retrospective review of our prospectively maintained database of patients undergoing RAPN from September 2020 to August 2024. Patients were categorized by the postoperative day of their discharge: POD1 (single overnight stay) or POD > 1 (more than one night stay).

Objective: To compare the effects of transperitoneal and retroperitoneal approaches for robotic assisted partial nephrectomy (RAPN) in patients with renal cell carcinoma (RCC).
Methods: We conducted a retrospective cohort study on RAPN at Affiliated Hospital of Jiangsu University. Between September 2020 and February 2024, the included patients underwent either transperitoneal approach or retroperitoneal approach.

Background: The aim of this study was to evaluate the differences in perioperative outcomes between transperitoneal and retroperitoneal techniques in cutaneous ureterostomy (CUS).
Methods: Between 2018 and 2023, 55 patients underwent CUS following robot-assisted radical cystectomy. Among the 55 patients, we compared 33 patients who underwent transperitoneal CUS (t-CUS) and 22 who underwent retroperitoneal CUS (r-CUS).

Article Synopsis
- The study compares outcomes and complications of two types of laparoscopic surgery for large kidney stones: retroperitoneal laparoscopic pyelolithotomy (RLP) and transperitoneal laparoscopic pyelolithotomy (TLP), analyzing data from 273 patients.
- Findings show that while stone size was larger in the TLP group, both types had similar operation times, hospital stays, and complication rates, except for a significantly higher rate of postoperative fever in the TLP group.
- The study concludes that RLP may be a better alternative to TLP due to the lower incidence of postoperative fever, suggesting it could be a preferred method for treating large kidney stones.
