Laparoscopic Extravesical Ureteral Reimplantation: Technique

Laparoscopic extravesical ureteral reimplantation in children is currently a technically demanding procedure with sparse literature to aid in mastering the learning curve. We present our most recent technique and lessons learned after 20 cases in children 4–15 years of age. The literature is also reviewed to encapsulate the current state-of-the-art

Outcome of surgical management of non-palpable testes

Background: We reviewed the success rates of orchidopexies performed for non-palpable testes at our institution and correlated preoperative and intraoperative findings to eventual outcomes. Materials and Methods: We retrospectively reviewed ninty five medical records of patients who underwent laparoscopic exploration for the assessment of a non-palpable testes between 1996 and 2009. Intra-operative data for one hundrad eight non-palpable testes were collected. Operative success was defined as a testis comparable in size or slightly smaller than the contra-lateral testis with normal consistency on the last follow-up. Results: There were seventy (65%) viable testes at exploration, thirty one nubbins (29%) removed and 7 (6%) absent. In the seventy six unilateral cases, contra-lateral hypertrophy was found in twinty five (33%) testes. Of which, twinty one (84%) were associated with absent testes or finding of a nubbin rather than a viable testis. In contrast, absent testes or finding of a nubbin was noted in 12 of 51 (23.5%) patients without contra-lateral hypertrophy. The difference was statistically significant (P 0.83). Interpretation: Testicular atrophy rate was similar in both artery sparing and Fowler-Stephens orchidopexies. Contra-lateral hypertrophy was significantly associated with absent testes or finding of a nubbin rather than a viable testis

Influence of postnatal hydroureter in determining the need for voiding cystourethrogram in children with high-grade hydronephrosis

Objective: To evaluate the utility of hydroureter (HU) to identify high-grade vesico-ureteric reflux (VUR) in patients with high-grade postnatal hydronephrosis (PH). Patients and methods: We retrospectively reviewed patients’ charts that had antenatal hydronephrosis from 2008 to 2014. Patients were excluded if they presented with febrile urinary tract infection (fUTI), neurogenic bladder, posterior urethral valve, multi-cystic dysplastic kidney, and multiple congenital malformations. We reviewed postnatal ultrasonography images and patients with Society of Fetal Urology (SFU) Grades 3 and 4 hydronephrosis with a renal pelvic antero-posterior diameter of ≥10 mm were included. The ureter was assessed and considered dilated if the ureteric diameter was  ≥4 mm. The voiding cystourethrogram (VCUG) studies, fUTI incidence, and surgical reports were reviewed. Results: Of the 654 patients reviewed, we included 148 patients (164 renal units) of whom 113 (76.4%) were male and 35 (23.6%) female. SFU Grade 3 PH was identified in 49% of the renal units, with the remaining 51% being SFU Grade 4. HU was found in 50/164 renal units and was not detected in the remaining 114 units. VUR was diagnosed in four units (3.5%) without HU (low-grade VUR); whilst it was detected in 19 units (38%) with HU (72.7% were high-grade VUR) (P < 0.001). VUR was diagnosed on the contralateral side in four/105 patients with PH without HU and diagnosed in 10/43 patients with PH with HU (P < 0.001). During a median follow-up of 25.9 months, none of the renal units that had VUR without HU developed UTI or had surgeries. Conclusion: Low-grade uncomplicated VUR was diagnosed in 3.5% of renal units without HU. Our results support limiting the use of VCUG to renal units with PH if associated with HU
