OBJECTIVES: To present our results after valve ablation using a novel cold knife urethrotome.
METHODS: Eleven consecutive male patients with posterior urethral valves underwent cold knife valvulotomy using a modified optical pediatric urethrotome. Patients were assessed both pre- and postoperatively using serum creatinine, voiding cystourethrography, and renal/bladder ultrasonography.
RESULTS: From August 2003 to August 2005, 11 patients underwent cold knife valvulotomy, of whom 7 returned for postoperative follow-up (mean follow-up 17.4 months). At surgery, the patients ranged in age from 5 days to 9 years. At presentation, 5 of the 7 patients had an elevated serum creatinine (mean 2.5 mg/dL, range 0.3-6.5), all had bilateral hydronephrosis of at least grade 3, and 6 of 7 had at least grade 3 reflux on 1 side. Intraoperatively, 1 complication (minor urethral laceration) occurred. Postoperatively, all 6 patients with serum creatinine levels measured showed improvement in renal function (mean creatinine 0.47 mg/dL, range 0.2-0.9). For the 6 patients who underwent postoperative ultrasonography, 4 had either complete resolution or significant improvement in their hydronephrosis, and none showed worsening. Six patients underwent postoperative voiding cystourethrography, with 5 showing either marked improvement or complete resolution of their reflux and 1 showing stable, unilateral reflux.
CONCLUSIONS: Valvulotomy using our modified urethrotome is a safe and effective technique for valve ablation.
