Predictors for lower urinary tract symptoms in patients underwent radical prostatectomy: implications for postoperative nursing care.

PMID 34514675WHAT IT FOUND
In men after prostatectomy, pelvic floor muscle exercise was linked with fewer urinary symptoms; body mass index 25 or higher was linked with more.
Catheter clamping and catheter duration were not.
Key findings
0135 of 65 enrolled patients had postoperative lower urinary tract symptoms (53.85%).
02When other factors were accounted for, BMI 25 kg/m2 or higher was associated with postoperative LUTS, and pelvic floor muscle exercise was associated with lower LUTS.
03Intermittent catheter clamping and catheterisation duration 1 month or more were not significantly associated with LUTS.

What it does not show
The sample was small (65 patients), so chance and confounding could explain the associations. The study did not randomise patients to pelvic floor muscle exercise or catheter clamping, so it cannot show that either caused the observed differences. LUTS was not measured with a validated score or quantified severity, so the outcome may be imprecise. Follow-up was only at 3 months, so it cannot show how symptoms changed over time or whether effects persist. All patients were from one hospital, so results may not apply elsewhere.
Declared interests
The authors declare no conflicts of interest, financial or otherwise.
The easy way to misread this
Do not read this as proof that pelvic floor muscle exercise prevents postoperative lower urinary tract symptoms. It was a small observational study of 65 patients without randomised comparison, and LUTS was not measured with a validated score.
