Perineal urethrostomy: A single-stage viable option for complex anterior urethral strictures

Abstract

Introduction: Perineal urethrostomy (PU) is a valid single stage option with maximum success to manage complex anterior urethral strictures. Aims: To evaluate the functional outcome of permanent PU using the Blandy technique in older patients or PU with staged reconstruction in young patients with severely diseased distal urethra. Materials and Methods: This is a retrospective analysis of 124 patients. They underwent Blandy's PU with or without Johanson stage 1. Exclusion criteria included patients with posterior urethral strictures or bladder neck contractures. Results: Mean age of patients was 54 years. Strictures due to catheterisation or instrumentation were most common – 85 (68.54%). Out of 124 patients, 71(57.3%) of them were posted for PU with Johanson stage 1 and 53 for PU only (42.7%) according to patients' choice. In patients age below 50 years, PU (N=10), PU with Johanson stage 1 (N=40) and Johanson stage 2 (N= 8) patients had mean Qmax of 20.2ml/s (17-24), 20.7ml/s (16-26), 16.375ml/s (14-18) respectively. In patients age> 50 years, PU (N=43), PU with Johanson stage 1 (N=31) and Johanson stage 2 (N= 4) patients had mean Qmax of 16.41ml/s (11-24), 17.25ml/s (11-25) and14.75 ml/s (12-17) respectively.For patients with only PU, 8/53 patients (15.09%) required secondary intervention (stomal dilatation N=6 and TURP N=2) while in PU with Johanson stage 1 patients, 10/71(14.08%) required secondary intervention (Stomal dilatation N=6, 8.45% and TURP N= 4, 5.6%). 112/124 (90.32%) were considered successful. Conclusion: Since most of patients have suffered for years, PU provides results in one stage.
