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 cmH 2 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 cmH 2 O had significantly higher 24PW (mean 825 g, median 768 g) when compared with patients with RLPP >30 cmH 2 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.
