Prediction of surgical necessity in children with ureteropelvic junction obstruction using machine learning.

Background: Hydronephrosis developing at the ureteropelvic junction due to obstruction poses clinical challenges as it has the potential to cause renal damage.

Aims: This study aims to evaluate how well machine learning models such, as XGBClassifier and Logistic Regression can be used to predict the need for treatment in patients, with hydronephrosis resulting from ureteropelvic junction obstruction.

Methods: Hydronephrosis was diagnosed in the medical records of patients from January 2015 to December 2020.

Monitoring renal oxygenation status by near-infrared spectroscopy during ureterorenoscopy in children.

Background: : Near-infrared spectroscopy (NIRS) monitoring demonstrates renal blood flow, perfusion, and oxygenation changes. This study aimed to evaluate the effects of pediatric endourological interventions (PEI) on regional oxygen saturation value (rSO2) usingrenal NIRS monitoring.

Methods: Patients having bilateral inguinal surgery (group I), cystoscopy (group II), and ureterorenoscopy (group III), 20 patients in each group, were included in the study.

Evaluation of renal oxygenation by near-infrared spectroscopy during endoscopic injection of bulking agents in children with vesicoureteral reflux.

Background: Near infrared spectroscopy (NIRS) is the measuring of regional tissue oxygenation (rSO2) by interpreting oxyhemoglobin and deoxyhemoglobin signals that come back by transmitting near infrared light to tissues. The effect of endourological interventions on renal perfusion in children is largely unknown.

Aims: To evaluate the effects of endoscopic injection of bulking agents (EIBA) for vesicoureteral reflux (VUR) on renal oxygenation (RO) using renal NIRS monitoring, which shows renal perfusion and oxygenation changes.

An atypical complication after hypospadias repair: A combined dorsal and lateral subcoronal urethrocutaneous fistulas.

Urethrocutaneous fistula (UCF) is one of the most common complications of hypospadias repair (HR). We present an unusual combined lateral and dorsal subcoronal (CLDSC) UCFs. Dorsal UCF has not been reported in children yet.
