Summary
Single-site sutureless laparoscopic partial nephrectomy (LPN) significantly reduces warm ischemia time and operation duration. This technique offers a feasible approach for small renal tumors, achieving excellent cosmetic and oncological outcomes.
Area of Science:
- Urology
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Partial nephrectomy (PN) is standard for localized renal cancer.
- Laparoscopic PN (LPN) has a steep learning curve.
- Intracorporeal suturing in LPN prolongs operation and warm ischemia time.
Purpose of the Study:
- To evaluate a single-site sutureless LPN technique using hemostatic agents.
- To assess the impact on warm ischemia time and surgical outcomes.
- To determine feasibility and safety for small exophytic renal cancers.
Main Methods:
- Retrospective analysis of 52 patients undergoing LPN (2015-2018).
- Comparison between single-site sutureless LPN (33 patients) and traditional suture LPN (19 patients).
- Evaluation of operative time, warm ischemia time, renal function (eGFR), and oncological outcomes.
Main Results:
- Sutureless LPN had significantly shorter warm ischemia time (11.8 vs. 21.2 min) and operation time (167.9 vs. 193.7 min).
- Minimal urinary leakage observed in the sutureless group, resolving spontaneously.
- No significant differences in postoperative eGFR or hemoglobin levels.
- All tumors resected with clear margins; no recurrences during follow-up.
Conclusions:
- Single-site sutureless LPN is a feasible and safe technique.
- It effectively reduces warm ischemia time and operation duration.
- Offers excellent cosmetic and oncological results for select renal tumors.
