Hypothesis / aims of study
Transurethral resection of the prostate (TURP) in males with detrusor underactivity (DU) and bladder outlet obstruction (BOO) is debated.1,2
Aim of the study was to evaluate outcomes in males with detrusor underactivity (DU) underwent transurethral resection of the prostate (TURP).
Study design, materials and methods
We prospectively evaluated 51 patients underwent TURP for lower urinary tract symptoms with urodynamics (UD) diagnosis of DU. All males were stratified in two cohorts: one with bladder outlet obstruction (BOO), and a second one without BOO. UD was performed according to Good Urodynamic Practice. DU was defined as BCI weak class and Schaefer nomograms contractility classes Very Weak or Weak. BOO was defined as International Continence Society (ICS) nomograms class obstructed and Schaefer nomograms obstruction classes III-VI. Follow-up was performed considering International Prostate Symptom Score (IPSS), uroflowmetry (UF), post-void residual urine (PVR) and PVR ratio obtained from the ratio of PVR to bladder volume (BV: voided volume + PVR). IPSS was also stratified in three classes of LUTS severity: 0-7 moderate, 8-19 fair, 20-35 severe. Patients’ satisfaction was measured by VAS and a simple question. Q-square and T-Student tests were used for statistical analysis.
Interpretation of results
TURP in patients with detrusor underactivity lead to a significant improvement in all functional outcomes. Significant improvements were achieved in both obstructed and unobstructed males, and patients with DU and BOO had better results but with no statistical difference.
Moreover, subjective satisfaction was high in both populations.
