Summary

Urethral stricture is a common complication after transurethral prostatectomy. Routine uroflowmetry screening is recommended, with further investigation for a maximal urinary flow rate (Qmax) below 10 mL/second.

Area of Science:

  • Urology
  • Surgical Complications

Background:

  • Urethral stricture is the most frequent late complication following transurethral prostatectomy.
  • Current understanding of urethral stricture etiology remains incomplete.
  • Routine postoperative uroflowmetry is advised for screening, with a maximal urinary flow rate (Qmax) below 10 mL/second indicating further investigation.

Purpose of the Study:

  • To review the common late complications of transurethral prostatectomy.
  • To highlight the need for further research into the unclear etiology of urethral strictures.
  • To discuss potential prophylactic methods and the necessity of randomized studies.

Main Methods:

  • Literature review focusing on transurethral prostatectomy complications.
  • Analysis of recommended screening procedures like uroflowmetry.
  • Examination of potential etiological factors and prophylactic strategies.

Main Results:

  • Urethral stricture is the most common late complication of transurethral prostatectomy.
  • Uroflowmetry is the recommended screening tool; Qmax < 10 mL/second warrants further investigation.
  • Etiology remains unclear, with potential roles for infection, catheterization, and urethral characteristics.

Conclusions:

  • Urethral stricture is a significant postoperative complication requiring vigilant screening.
  • Further randomized studies are essential to elucidate etiological factors and evaluate prophylactic interventions.
  • Perineal urethrotomy may help avoid anterior urethral strictures, but preoperative internal urethrotomy effects are conflicting.
