Ureterosciatic hernia is extremely rare. In ureteral herniation, ureter prolapses occur through either the greater or lesser sciatic foramen. Atrophy of the piriformis muscle, hip joint diseases, and defects in the parietal pelvic fascia are predisposing factors for the development of ureterosciatic hernia. Most symptomatic patients have been treated surgically, with conservative treatment reserved only for asymptomatic patients. To the best of our knowledge, long-term follow-up outcomes after ureterosciatic hernia management are sparse. In this paper, we report the case of a 68-year-old woman who presented with colicky left abdominal pain. After computed tomography (CT) scan and anterograde pyelography, she was diagnosed ureterosciatic hernia with obstructive uropathy. We performed ureteral balloon dilatation and double-J ureteral stent placement. After this minimally invasive procedure, CT scan demonstrated that the left ureter had returned to its normal anatomical position without looping into the sciatic foramen. The patient remained asymptomatic with no adverse events 7 years after the minimally invasive procedures. This brief report describes ureterosciatic hernia successfully managed with minimally invasive procedures with long-term follow-up outcomes.

Purpose: To compare patients with sepsis due to obstructive urolithiasis (Sep-OU) and underwent drainage by percutaneous nephrostomy (PCN) or a double-J (DJ)-ureteral stent and to identify predictive risk factors of DJ stent failure in these patients. Materials and Methods: We reviewed our records from January 2013 to July 2018 and identified 286 adult patients with Sep-OU out of which 36 had bilateral involvement, thus total 322 renal units were studied. Urologic residents in training carried out both ureteral stenting and PCN tube placement. Demographic data and stone characteristics were recorded along with Charlson comorbidity index. For predicting risk factors of DJ stent failure, those variables that had a p-value <0.1 in univariate analysis were combined in a multinomial regression analysis model. Results: The patients with PCN placement were significantly older than those with DJ stent placement (p=0.001) and also had significant number of units with multiple calculi (p=0.018). PCN was also placed more frequently in those patients with a upper ureteric calculi (p<0.05). On multinomial regression analysis multiple calculi (p=0.014; odds ratio [OR], 4.878; 95% confidence interval [CI], 1.377-17.276) and larger calculi size (p=0.040; OR, 0.974; 95% CI, 0.950-0.999) were the significant predictors of DJ stent failure. Conclusions: In patients with sepsis from obstructive urolithiasis due to larger and multiple calculi a PCN placement might be better suited although this data requires further prospective randomized studies to be extrapolated.

Bilateral renal obstruction is a rare critical condition, requiring a prompt diagnostic approach and treatment to restore the renal function. The most commonly observed obstructive uropathy in children is congenital malformation, such as posterior urethral valves and bilateral ureteropelvic junction obstruction. Malignant pelvic masses obstructing the ureter are widely reported in adults but are rarely observed in children. The treatment of ureteral obstruction related to pelvic malignancy is a therapeutic challenge with a median survival duration of 3-7 months in adults; however, pediatric patients with pelvic malignancy leading to ureteral obstruction had better outcomes, with a reported 5-year mortality rate of 20%, than the adult patients. Here, we report a rare case of bilateral ureteral obstruction associated with pelvic rhabdomyosarcoma presenting with acute kidney injury treated by ureteral diversion with double J stent, and concommittent emergency hemodialysis, leading to restoration of good renal function. We suggest that bilateral ureteral obstruction should be released as soon as possible using surgical or interventional approach to minimize the obstruction period, and subsequential chemotherapy may contribute to improvement of survival and recovery of renal function.

요낭종이란 신장 및 비뇨기계로부터 누출된 소변이 신장 및 신우 주위에 캡슐상의 낭종을 형성하는 드문 질환으로 자연발생적인 신우의 파열로 인한 누출은 매우 드물며, 대부분 요로와 신우 내강의 압력 증가에 의해 발생한다. 본 증례에서 18세 여자 환아는 내원 7일 전부터 시작된 고열과 핍뇨 및 호흡곤란을 주소로 내원하였다. 환아는 출생시 다운 증후군을 진단받았으며 평소 배뇨는 원활하였다. 입원 후 환아는 패혈증 쇼크 및 급성 신손상, 급성 호흡 곤란 증후군 진단 하에 항생제 및 스테로이드 충격 요법 시행 후 핍뇨, 호흡곤란 및 혈액검사 호전 소견 보였으나 7일 동안 유치된 도뇨관 제거 후 환아는 요 폐색 소견이 관찰되었다. 복부 전산화 단층 촬영상 좌측 신장 주위에 요낭종이 확인되어 좌측 요관에 Double-J catheter가 삽입 되었으며 신우의 파열 부위에 조영제 누출이 확인되었다. 시술 후 요 폐색 소견은 호전되었고, 배뇨성 방광 요도 조영술 상 좌측 신장의 4단계 방광 요관 역류가 관찰되었다. Double-J catheter 제거 3개월 후 좌측 신장 주변의 요낭종은 대부분 소실되었고, 좌측 신장의 방광 요관 역류는 보이지 않았다. 저자들은 급성 신부전 환아에서 유치 도뇨관 제거 후 배뇨곤란 및 요 폐색 소견을 보인 신 주위 요낭종 1례를 경험하였기에 보고하는 바이다.
