    Abstract:
    AIM: To assess the correlation between retrograde leak point pressure (RLPP) and 24-hr pad weight (24PW) in men with post-prostatectomy incontinence. METHODS: We performed RLPP and 24PW measurements on 61 patients with a history of post-prostatectomy stress urinary incontinence (SUI). We examined the relationship of RLPP and 24PW. We also reviewed the urodynamic and clinical data of these patients to explain our findings. RESULTS: The mean age was 70 years (SD ± 7.4, range: 51-87). The mean RLPP was 36.8 cmH2 O (SD ± 15.3, range: 9-76), the mean 24PW was 499 g (±677 g, range: 16.5-3,177 g). There was a good and significant negative correlation between RLPP and 24PW (r = 0.56, P < 0.01). RLPP was able to differentiate between cases of mild/moderate (<400 g) and severe (≥400 g) incontinence. Patients with RLPP <30 cmH2 O had significantly higher 24PW (mean 825 g, median 768 g) when compared with patients with RLPP >30 cmH2 O (mean 257.8 g, median 100 g, P < 0.01). CONCLUSIONS: RLPP could be used as an objective and potentially more reliable substitute to pad weight to objectify and stratify SUI in post-prostatectomy patients. Neurourol.
