Ultrasound-guided hydrostatic enema reduction of intussusception and confirmation with single abdominal radiograph in children.

PURPOSE: To detect false-positive reduction results after ultrasound (US)-guided hydrostatic intussusception reduction, we have incorporated water-soluble contrast material to the enema fluid and confirmed the reduction with a single abdominal radiograph. We present the results of the combined imaging method for the reduction of intussusception in children. MATERIALS AND METHODS: The records of the patients who were treated for intussusception were analyzed retrospectively. Patients were divided into two groups: a US-guided reduction group and a US-guided reduction plus radiographic control group. The patient characteristics, symptoms, treatment methods, outcomes, and complications and follow-up were analyzed. RESULTS: A total of 164 intussusception episodes were treated in 153 patients. Hydrostatic reduction of intussusception was performed in 59 patients in the US-guided group and in 94 patients in the US-guided plus radiographic control group. Recurrence rate in the US-guided group was 15.7%, vs 3.5% in the US-guided plus radiography group (P = .029). In the US-guided plus radiographic control group, 5 (5.3%) false positive reductions under US guidance were determined by abdominal radiography. CONCLUSION: In order to decrease false positive reduction rate and early recurrence, US-guided intussusception reduction can be performed with saline plus water-soluble contrast material and confirmation of reduction obtained with a single direct abdominal radiograph.

Urinary continence after high urogenital sinus repair conducted with posterior prone approach: electromyography-uroflowmetric assessment.

PURPOSE: We aimed to present the results of urinary continence assessment objectively with electromyography (EMG)-uroflowmetry after high urogenital sinus (HUGS) repair with posterior prone approach without division of rectum. METHODS: The records of patients who underwent HUGS repair via posterior prone approach between January 2005 and July 2018 were reviewed retrospectively. Incontinence, dysuria, hesitation, and straining during urination were evaluated during the clinical follow-up. Dysfunctional voiding scoring system was used as a questionnaire. Patients were re-evaluated with EMG-uroflowmetry in terms of voiding volume and pattern, voiding time, maximum flow rate, average flow rate, maximum flow time, and post-voiding residual volume. RESULTS: Seven patients with HUGS were treated with a posterior prone approach. The median age of the patients was 18 months (8-21 months). The median UGS length was 4.4 cm (3.6-5.5 cm), urethral length was 1.1 cm (1.0-1.5 cm), and vaginal length was 4.9 cm (4.1-5.1 cm). No urination or defecation problems were described by the patients or their parents. When the results of the dysfunctional voiding scoring systems questionnaire were analyzed, results scored 7 (range 5-8). EMG-uroflowmetric test graphics of the patients showed normal flow curves without plateau, intermittency or irregularity. Pelvic EMG assessment was normal in all patients. CONCLUSION: EMG-uroflowmetry has shown objectively that urinary continence and normal voiding pattern are preserved after HUGS repair with posterior prone approach without division of rectum.
