Magnitude of post-urethroplasty urinary tract infections in children with hypospadias at a tertiary hospital in Kenya.

J Pediatr Urol 2021 Apr 28. Epub 2021 Apr 28.

Kenyatta National Hospital, Kenya.

Introduction: Children who have undergone urethroplasty procedure for hypospadias are at a higher risk of getting urinary tract infections (UTI). This may be due to urethral scarring following urethroplasty that acts as a nidus for UTI. The risk is also attributed to urine stasis due to complications of urethroplasty such as urethral diverticulum, urethral stricture, meatal stenosis or breakdown of urethroplasty. Read More

Robotic assisted proximal dorsal urethral diverticulectomy.

Int Urogynecol J 2021 Feb 26. Epub 2021 Feb 26.

Department of Urology, Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA.

Introduction And Hypothesis: Urethral diverticula are rare but clinically significant entities among female patients. Ventrally located, mid-to distal, simple or horseshoe diverticula are most commonly observed and are usually repaired via a transvaginal approach with varying levels of difficulty but high success rates. Dorsally (anteriorly) located urethral diverticula are more challenging to repair secondary to the need to access the side of the urethra opposite the vaginal lumen, abutting the external urethral sphincter.
