Here, we report two cases of renal pelvic hematoma following RAP: A 9\u2010year\u2010old girl (Case 1) and a 25\u2010year\u2010old man (Case 2), both diagnosed with left ureteropelvic junction obstruction. Both underwent transperitoneal Anderson\u2013Hynes pyeloplasty using 5\u20100 absorbable monofilament sutures. Postoperative imaging revealed renal pelvic hematoma in each case. Both patients remained hemodynamically stable and were managed conservatively. In Case 1, the hematoma and urine were aspirated through a 6 Fr ureteral catheter, whereas in Case 2, symptoms resolved spontaneously. Follow\u2010up imaging demonstrated preserved renal function and improvement of hydronephrosis in both cases. Renal pelvic hematoma after RAP is rare but can be managed conservatively in stable patients. Careful intraoperative hemostasis and awareness of this complication are essential to ensure favorable outcomes.<\/jats:p>","DOI":"10.1111\/ases.70234","type":"journal-article","created":{"date-parts":[[2026,1,7]],"date-time":"2026-01-07T18:10:28Z","timestamp":1767809428000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Renal
