Laparoscopic radical prostatectomy: omitting a pelvic drain.

Area of Science:

• Urology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Laparoscopic radical prostatectomy (LRP) with running urethrovesical anastomosis (RUVA) is a standard treatment for prostate cancer.
• The necessity of pelvic drain placement after LRP with RUVA remains a topic of clinical debate.
• Assessing outcomes of selective drain placement strategies is crucial for optimizing patient care.

Purpose of the Study:

• To evaluate the outcomes of a selective drain placement strategy during LRP with RUVA.
• To determine the impact of drain placement on postoperative urine leak rates and other complications.
• To correlate cystographic findings with drain usage in patients undergoing LRP.

Main Methods:

• Retrospective review of patients undergoing LRP with RUVA between January 2003 and December 2004.
• Anastomosis performed using a modified van Velthoven technique.
• Pelvic drains placed selectively based on surgeon's discretion, intraoperative findings, and clinical suspicion of urinary leak. Routine postoperative cystograms obtained.

Main Results:

• A total of 208 patients underwent LRP with RUVA; data for 206 were analyzed.
• The overall rate of cystographic urine leak was 5.8%.
• Patients with drains had a significantly higher leak rate (15.6%) compared to undrained patients (2.5%) (p = 0.002). No urinomas or hematomas were observed in either group. Three lymphoceles occurred in undrained patients.

Conclusions:

• Routine pelvic drain placement after LRP with RUVA is not necessary when anastomotic integrity is adequate.
• Surgeon's clinical judgment is effective in identifying patients at risk for postoperative leakage.
• Omitting drains in low-risk patients does not appear to increase morbidity, including lymphocele formation.
