We analysed 28 patients with urological problems who have been evaluated or treated with endoscopy during neonatal periods. The underlying urological disorders included hydronephrosis in 9, ureterocele in 4, multicystic kidney in 3, megauteter in 3, posterior urethral valve in 2, ectopic ureter in 2, VUR in 2, and 3 other disorders. Endoscopic operations with either electrode or cold knife was done on 7 patients with posterior urethral valve, ureterocele or uethral stricture. Retrograde ureteral catheterization was done on 17 patients, mainly with PUJ stenosis, multicystic kidney or megaureter. Endoscopic examination was done on 4 patients with VUR or ectopic ureter to see location and configuration of the ureteral orifice. Accurate diagnosis was made on 27 neonates (96%) through endoscopy. The remaining one patient required urodynamic study because no anatomical abnormality was found on endoscopy. Intraoperative or early postoperative complication was seen in 6 patients including 5 with edema of the penile shaft or bleeding from the urethra and one with extravasation of contrast medium from the lower ureter during the retrograde study. Late complication was seen in 2 patients ; one with incomplete resection of the urethral valve, and another with recurrence of urethral stricture. Most of the complications can be prevented by careful and gentle technic.
