Summary
Bilateral nerve-sparing radical retropubic prostatectomy (RRP) offers improved erectile function recovery for prostate cancer (PCA) patients compared to unilateral procedures. Approximately 50% of patients regain sufficient erections for intercourse without aids after bilateral RRP.
Area of Science:
- Urology
- Oncology
- Sexual Medicine
Background:
- Nerve-sparing radical retropubic prostatectomy (RRP) is increasingly used for localized prostate cancer (PCA).
- Patient-reported outcomes, particularly erectile function, are crucial for evaluating surgical success.
Purpose of the Study:
- To analyze post-operative erectile function after unilateral and bilateral nerve-sparing RRP.
- To compare the efficacy of uni- vs. bilateral nerve-sparing RRP in restoring erectile function.
Main Methods:
- Retrospective analysis of 366 patients undergoing uni- or bilateral nerve-sparing RRP (1992-1999).
- Indication for nerve-sparing based on multivariate analysis (CART).
- Erectile function assessed via questionnaires (IIEF-5) at 12-month follow-up.
Main Results:
- Unilateral RRP yielded 13-29% sufficient erections for intercourse; some tumescence in 37-73%.
- Bilateral RRP (periods 3-5) showed significantly higher rates: 61% (period 3), 50% (period 4), 52% (period 5).
- Younger patients (<60) had better outcomes than older patients (> or =60).
Conclusions:
- Bilateral nerve-sparing RRP demonstrates superior erectile function recovery compared to unilateral RRP.
- Approximately 50% of patients achieve intercourse-suitable erections after bilateral nerve-sparing RRP without pharmacologic assistance.
