ABSTRACT

Aim: To evaluate which technique of pyeloplasty stented or non-stented is better for management of PUJ obstruction in paediatric patients.

Study design: Randomized controlled trial

Place and duration: Paediatric Surgical Department of Bahawal Victoria Hospital, in collaboration with Pathology Department Quaid e Azam Medical College Bahawalpur, from January 2019 to January 2021.

Methodology: A total of 60 patients who presented with obstruction of primary ureteropelvic junction were enrolled in study. Patients were divided into two groups (30 in each) and treated with stented and non stented pyeloplasty. Parenchymal diameter, GFR and serum creatinine, hospital stay are outcomes and fever, urinoma, restenosis and wound infection are complications. SPSS version 23 was used for data analysis.

Results: The mean S-Creatinine and parenchymal diameter before and after surgery in stented group were not significant. The mean GFR after surgery was greater than before surgery, (p=0.000). Mean APPD and parenchymal diameter before and after surgery in non-stented group was not significant. The mean GFR after surgery was greater than before surgery, (p=0.000).

Conclusion: Pyeloplasty with stents and without stents is equally effective for the treatment of PUJ obstruction. Parenchymal diameter improved in both groups and but statistically not significant, GFR also improved in both groups and significant. Complications are more in non stented group but probability is not significant.
