“…Jain et al have suggested a way to differentiate between AUV and CAUD. In AUV, the proximal lip of the diverticulum is obtuse while in CAUD, it is acute (Figure 5) [8]. This may be evident on urethrogram, which can help in differentiating the two conditions or during cystoscopy like our case, as can be seen in Figure 3.…”

“…Some children may present antenatally with an obstructive picture on antenatal ultrasound but the majority present postnatally with lower urinary tract symptoms including difficulty in micturition, dribbling of urine, poor urinary stream, and/or UTI. In severe cases, they may present with renal failure and gross upper tract changes [6][7][8]. Parents usually report that the child has never had a good urinary stream since birth.…”

“…One reason for this confusion is that in both conditions, there is dilatation of the distal urethra, which may appear similar. The other reason is that in CAUD, there is an acute angulation at the proximal end of the diverticulum, which during micturition not only causes filling of the diverticulum but also lifts it up and causes obstruction of the urethra leading to obstructive symptoms similar to AUV [8]. Jain et al have suggested a way to differentiate between AUV and CAUD.…”

“…If the condition is minor, it can be either left as such or treated cystoscopically by incising the distal lip of the diverticulum [8][9][10][11]. This will stop the distal mucosal fold from acting as an obstructive valve and the diverticulum will become a self-emptying diverticulum.…”

Congenital anterior urethral diverticulum is a rare condition causing lower urinary tract obstruction in children. It usually arises from the ventral aspect of the anterior urethra, mostly located at the penoscrotal junction. We report a case of a 14-month-old baby boy who presented with a soft ventral swelling over the distal penile urethra, difficulty in passing urine, and a history of recurrent febrile urinary tract infections. A retrograde urethrogram revealed a large distal anterior urethral diverticulum. He underwent diverticulectomy and primary repair with no post-operative complications. The treatment of these depends on the size of the diverticulum and the degree of obstruction. In cases of a large anterior urethral diverticulum, open diverticulectomy and primary repair are recommended.

BackgroundUrethral diverticulum (UD) is a poorly defined anomaly consisting of an outpouching of the urethra. Management without surgical resection is not previously reported in dogs.Hypothesis/ObjectivesReport the outcome of male dogs presented for urinary incontinence with UD treated with an artificial urethral sphincter (AUS).AnimalsEight client‐owned dogs with UD treated with an AUS.MethodsMulticenter retrospective study. Medical records from male dogs with urinary incontinence were reviewed. Inclusion criteria: diagnosis of a UD by retrograde cystourethrography, cystoscopy, abdominal ultrasonography or contrast computed tomodensitometry (CT) or a combination of these modalities, AUS placement, and at least 1 follow‐up. Urinary continence score (UCS) was attributed retrospectively.ResultsMedian UCS at presentation was 1/5. A contrast cystourethrogram was diagnostic in 8/8 dogs. All diverticula were saccular, and 7/8 were within the prostatic urethra and 1/8 extended up to the membranous urethra. A congenital origin was suspected in 7 dogs and acquired in 1. Concurrent anomalies included renal dysplasia or chronic pyelonephritis (n = 4), bilateral cryptorchidism (n = 3), and pelvic urinary bladder (n = 3). All dogs were poorly/moderately responsive to phenylpropanolamine. Artificial urethral sphincter placement resulted in improvement in continence in all dogs with a median UCS of 4/5 (5/5 in 2/8 dogs, 4/5 in 5/8 dogs, 3/5 in 1/8 dogs).ConclusionUrethral diverticulum should be considered in male dogs with persistent urinary incontinence not responding to medical management. Artificial urethral sphincter placement is an effective therapeutic option that improved continence scores in all dogs.
