What this Trial Is About

This research aims to evaluate whether renal cortical shear wave elastography can predict the recovery of kidney function after open pyeloplasty in children with unilateral primary ureteropelvic junction obstruction. This condition causes hydronephrosis and may impair kidney function, but surgery can potentially restore it. The study is a prospective observational cohort conducted at Beni-Suef University and focuses on children aged 6 months to 18 years. Participants will undergo standard open dismembered pyeloplasty surgery. Before surgery, children will have clinical assessments, lab tests, renal ultrasound, shear wave elastography to measure kidney stiffness, and renal isotope scans. After surgery, follow-up visits at 3 and 6 months will include clinical checks, ultrasound, shear wave elastography, and a repeat renal isotope scan to assess kidney function and drainage. Throughout the study, researchers will monitor changes in renal cortical shear wave elastography and compare these with isotope scan results to predict kidney function recovery. They will also track changes in ultrasound findings and renal function over time. The main focus is to see how well the change in elastography from before surgery to 3 months after predicts function at 6 months. The total participation lasts at least 6 months after surgery for each child.

Your Study Journey

Screening

Duration - 2 to 4 weeks

Participants are screened for eligibility to participate in the trial.

1 visit (in-person)

Diagnostic Evaluation

Duration - Up to the day of surgery

Participants undergo preoperative clinical assessment, laboratory investigations, renal ultrasonography, renal cortical shear wave elastography, and renal isotope assessment to evaluate kidney function and obstruction.

1 to 2 visits before surgery

Surgery

Duration - Day of surgery

Participants undergo open dismembered pyeloplasty following standard surgical procedures to correct unilateral ureteropelvic junction obstruction.

1 in-person surgical visit

Post-operative Follow-up

Duration - 6 months after surgery

Participants receive clinical assessments, renal ultrasonography, and renal cortical shear wave elastography at 3 and 6 months after surgery, including repeat renal isotope studies to monitor kidney function recovery.
