摘要

Background

In this study, we aimed to present the imaging and surgical results of our pediatric UPJO patients and to discuss our findings in the context of the current literature.

Methods

All medical records of children who underwent open pyeloplasty due to UPJO were reviewed retrospectively. Obtained data included patient demographics, clinical symptoms, ultrasonographic and scintigraphic imaging, intraoperative details, length of hospital stay and complications.

Results

114 patients underwent 124 open dismembered pyeloplasties for UPJO. Anderson-Hynes dismembered pyeloplasty technique was used except Y–V plasty in a recurrent patient. Significant changes in mean hydronephrosis degree, pelvic anterior–posterior diameter and parenchymal thickness were observed. The mean preoperative ipsilateral differential renal function was 37%, and it was calculated as 36% postoperatively. Pelviostomy catheter was used in 11 kidneys, double-J stent was used in 108 kidneys and no catheter was used in 5 kidneys. The mean operative time was 98 min. The mean length of hospital stay was 4.6 days. The mean postoperative follow-up period was 5.1 years. Recurrent UPJO was seen in 5 of 124 kidneys (4%).

Conclusion

Open dismembered pyeloplasty remains a highly successful and feasible surgical option in the treatment of pediatric UPJO, and our findings are consistent with outcomes reported in the current literature.
