Follow-up and outcome measurements
stricture, obstructive lower urinary tract symptoms
STRICTURE
Patients were followed up after catheter removal and at 1, 3, 6 and 12 months after the operation. All patients were evaluated in each follow-up visit with IPSS, ultrasound and uroflowmetry. Retrograde urethrogram was done at 6 and 12 months of follow-up period. Successful treatment means spontaneous voiding without any persistent symptoms or significant PVR with Qmax > 15 mL/s without any requirement of auxiliary manoeuver. Failure was defined as the presence of obstructive lower urinary tract symptoms, Qmax < 10 mL/s, recurrent stricture by retrograde urethrogram or the need for any auxiliary procedure including dilatation, another internal urethrotomy or urethroplasty.
