Laparoscopic simple nephrectomy after previous ipsilateral open versus percutaneous renal surgery.

Area of Science:

• Urology
• Minimally Invasive Surgery
• Nephrology

Background:

• Previous open or percutaneous renal surgery can cause fibrosis, potentially complicating subsequent laparoscopic nephrectomy.
• Assessing the feasibility and outcomes of laparoscopic nephrectomy in patients with a history of ipsilateral renal surgery is crucial.

Purpose of the Study:

• To prospectively compare the outcomes of transperitoneal laparoscopic nephrectomy in patients with a history of either open renal surgery or percutaneous nephrolithotomy.
• To evaluate the safety and efficacy of laparoscopic nephrectomy in challenging surgical fields.

Main Methods:

• A prospective study evaluated 38 patients undergoing transperitoneal laparoscopic nephrectomy after ipsilateral open renal surgery (n=22) or percutaneous nephrolithotomy (n=16).
• Patients had symptomatic, nonfunctioning, small, or hydronephrotic kidneys.
• Outcomes included operative time, conversion rates, intraoperative complications, blood loss, and postoperative recovery variables.

Main Results:

• Two conversions to open surgery occurred in the open surgery group due to pedicle dissection difficulty.
• Operative times were similar (mean 111 min vs. 97 min, P=.22).
• Intraoperative complications, blood loss, and postoperative recovery (oral intake, hospital stay, ambulation) were comparable between groups.

Conclusions:

• Transperitoneal laparoscopic nephrectomy is feasible and can be performed in a timely manner in patients with prior ipsilateral renal surgery.
• With sufficient laparoscopic expertise, similar perioperative outcomes are achievable regardless of the type of prior renal surgery.
• Precautionary measures for laparoscopic nephrectomy are consistent for patients with prior percutaneous nephrolithotomy and open flank surgery.
