Abstract

Aims: The aim of the study was to evaluate the transurethral resection of the prostate (TURP) outcomes of unobstructed patients with detrusor underactivity (DUA), comparing the surgical results between obstructed and unobstructed males with concomitant DUA, at midterm follow-up.

Methods: This was an observational, prospective, comparative, nonrandomized study. Candidates to TURP underwent preoperative urodynamics (UD), with a diagnosis of DUA, were divided in two cohorts: Group A unobstructed men, group B males with bladder outlet obstruction (BOO). Males were evaluated yearly with uroflowmetry (UF), post-void residual (PVR), and bladder voiding efficiency (BVE), International Prostate Symptom Score (IPSS) questionnaire, visual analogic scale (VAS) for subjective assessment of the quality of life. The degree of the variation of maximum flow rate (Qmax), PVR, BVE, IPSS, VAS between baseline and follow-up (Δ) was evaluated.

Results: Patients in group A were 28 and in group B 23. Overall patient's mean ± SD age was 63.37 ± 12.41 years. Preoperative urodynamics characteristics: mean bladder contractility index (BCI) of 61.15 and 76.25 in group A and B, respectively; mean bladder outlet obstruction index (BOOI) of 17.25 and 50.15 in group A and group B, respectively. After surgery, overall patient group, group A, and group B showed a statistical improvement in IPSS score (P < .0001), Qmax (P < .0001), PVR (P < .0008), BVE (P < .03) and VAS (P < .0001).

Conclusions: BOO had an important impact on the degree of improvement of Qmax and PVR/BVE, while had a poor influence on lower urinary tract symptoms amelioration. The most relevant outcomes were found when BOO was associated with DUA, which was not a contraindication to surgery.
