Does hypertension develop in children patients who underwent pyeloplasty due to unilateral ureteropelvic junction stenosis
Abstract
Aims: Hypertension may develop in children with renal and cardiovascular pathologies. In our study, we aimed to investigate the prevalence of hypertension in children who underwent pyeloplasty.
Methods: We retrospectively evaluated the blood pressure values measured in the postoperative period in children who were diagnosed with ureteropelvic junction stenosis and underwent pyeloplasty in the pediatric urology clinic of Ankara City Hospital between 2007 and 2020.
Results: In our study, 167 patients (48 women, 123 men; mean age 3.6; 58 right, 109 left) who underwent pyeloplasty due to UPJO were evaluated. In the postoperative follow-up, hypertension was detect-ed in 5 patients (2.9%). Bilateral patients were excluded from the study. Of the 5 patients who developed hypertension, one had a pelvic ectopic kidney and one had a contralateral multicystic dysplastic kidney. All of the patients who developed hypertension had intrinsic UPJO; 3 of them were catheterized with a percutaneous nephrostomy catheter preoperatively. The mean MAG3 function was 43.3%. While the mean follow-up period of the patients was 5.6 years, it was ob-served that hypertension developed in an average of 3.5 years. In the postoperative period, there was an average increase of 1.2% in the functions of these five patients in the control scintigraphy. No patient who developed hypertension underwent a second surgical intervention.
Conclusion: In cases where pyeloplasty was performed due to UPJO, blood pressure should be monitored in the postoperative period. Blood pressure should be checked, especially in advanced hydronephrotic patients with a history of percutaneous nephrostomy in the preoperative period.
