Do bony pelvis parameters affect perioperative outcomes in open radical prostatectomy?

Area of Science:

• Urology
• Oncology
• Radiology

Background:

• Open radical prostatectomy (RP) is a standard treatment for localized prostate cancer.
• Predicting technical difficulties during RP is crucial for optimizing patient outcomes.
• Bony pelvic parameters are potential anatomical factors influencing surgical complexity.

Purpose of the Study:

• To assess the predictive value of bony pelvic parameters measured by CT scans.
• To determine if these parameters can estimate technical difficulties in open RP.
• To correlate pelvic measurements with perioperative outcomes.

Main Methods:

• Retrospective analysis of 100 patients undergoing open RP.
• Measurement of bony pelvic parameters using spiral CT images.
• Evaluation of operative difficulty indicators: positive surgical margin (PSM), vesicourethral anastomosis stricture (VUAS), urine leakage, operative time, catheterization time, and blood loss.

Main Results:

• No significant correlation found between bony pelvic parameters and PSM, VUAS, or urine leakage.
• Higher PSA levels and pathological tumor stage were associated with PSM (p<0.002).
• Pelvic parameters did not significantly correlate with operative time, blood loss, or catheterization time.

Conclusions:

• Bony pelvic parameters are unlikely to be significant predictors of perioperative outcomes in open RP.
• Elevated PSA levels and advanced pathological tumor stage are more indicative of surgical complexity and margin positivity.
