Abstract Background Pediatric hydronephrosis induced by pelvic-ureteric junction obstruction (PUJO) is treated by dismembered pyeloplasty (DP) via open and laparoscopic surgery. The etiology of PUJO involves both intrinsic stenosis and extrinsic compression of crossing vessels (CVs). PUJO owing to CVs is also treated by DP, as there is no consensus concerning this vascular condition. We encountered a 2-year-old infant with pure extrinsic PUJO combined with horseshoe kidney who successfully underwent laparoscopic transposition for CVs (vascular hitch). Case presentation A 2-year-old boy was prenatally diagnosed with left multicystic dysplastic kidney (MDCK) and right hydronephrosis and received a definitive diagnosis after birth. At 6 months old, renal scintigraphy revealed a non-functioning pattern in the left kidney and an obstructive pattern in the right, showing no response to furosemide loading. The patient also had recurrent urinary tract infection, and his right hydronephrosis gradually worsened. We decided to perform surgery for the right PUJO. Preoperative enhanced computed tomography detected three right renal vessels independently branching from the abdominal aorta. The middle renal vessels were located at the ventral side of the pelvis and coincident with the site of PUJO. These vessels were suspected of being CVs. The patient underwent laparoscopic surgery electively. A 5-mm trocar was inserted at the umbilicus for a 5-mm, 30° rigid scope. Two additional ports were then inserted under laparoscope inspection. The dilated right pelvis and CVs were detected after ascending colon mobilization. To confirm the pathogenesis of PUJO, the CVs were dissected and taped. After taping the CVs, an intraoperative diuretic test was performed using furosemide loading. Peristalsis of the right ureter was recognized, and the extrinsic PUJO owing to the CVs was definitively confirmed. We therefore performed transposition for the CVs (vascular hitch procedure). The CVs were mobilized in the cranial direction and those were wrapped by dilated pelvis. The post-operative course was uneventful. The renal scintigraphy findings improved and showed a favorable response of furosemide loading. Conclusions The laparoscopic vascular hitch procedure is minimally invasive and effective for extrinsic PUJO due to CVs. Anastomotic stricture after Anderson and Hynes DP can be prevented by appropriate patient selection.

Objective Surgery is still indicated as the treatment of choice in subset of patients with unilateral multicystic dysplastic kidney (UMCDK) because of its potential complications and malignant change. The purpose of this study is to present our observation that early nephrectomy may cure hypertension early in children with UMCDK and review the literature. Materials and Methods We report here four children (two males and two females) with antenatally diagnosed UMCDK with hypertension, treated in the past 4 years. All have antenatal diagnosis of UMCDK and referred to us after their birth. Diagnosis of hypertension (blood pressure > 95th percentile) was made after 3 months of follow-up in all patients. Nephrectomy was performed in all children in variable time duration. Hypertension, urinary tract infection, and desire of parents were the main indication of surgery. Results All children showed decrease in the size of their dysplastic kidney with time, but hypertension was persistent and needed antihypertensive drugs; even increase in the doses in successive follow-up. After nephrectomy, three children who were operated early got cured having normal blood pressure within variable time duration, while a child, operated late, still had high blood pressure and needed antihypertensive drugs. Conclusion Early nephrectomy in recently diagnosed hypertension in UMCDK is advisable and can cure hypertension early. Levels of Evidence The level of evidence is IV (case series with no comparison group).

Tóm tắt Đặt vấn đề: Đánh giá kết quả phẫu thuật nội soi sau phúc mạc điều trị bệnh lý thận, tiết niệu ở trẻ em Phương pháp nghiên cứu: Nghiên cứu hồi cứu người bệnh phẫu thuật nội soi sau phúc mạc điều trị bệnh lý thận, tiết niệu trong thời gian từ 1/1/2014 - 31/12/2017. Kết quả: Phẫu thuật nội soi sau phúc mạc cho 110 người bệnh trong đó hẹp khúc nối bể thận - niệu quản là 49 người bệnh (44,54%), thận niệu quản đôi 23 người bệnh (20,91%), thận đa nang 21 người bệnh (19,1%), thận teo mất chức năng 17 người bệnh (15,43%). Tuổi phẫu thuật trung bình là 4,5 ± 3,72 tuổi (từ 1 tuổi- 15 tuổi), tỉ lệ nam/ nữ = 3,3/1.

Abstract Introduction: To evaluate the retroperitoneal laparoscopic surgery in children having the urinary anomalies Material and Methods: Retrospective study for children suffering from urinary anomalies underwent retroperitoneal laparoscopic surgery. Results: 110 children were operated by retroperitoneal laparoscopic approach included: 49 patients (44.54%) with ureter pelvic junction obstruction, 23 patients (20.91%) with ureteral duplication, 21 patients (19.1%) with multicystic dysplastic kidney, 17 patients (15.45%) with atrophy kidney. Mean age was 4.5± 3.72 years old (from 1 year to 15 years old); Gender ratio: male/female = 3.3/1. Laparoscopic nephrectomy for 52 cases (47.27%), 58 cases including 11 cases (10%) retroperitoneal laparoscopic pyeloplasty and 47 cases (42.27%) with assisted laparoscopic plastic surgery. Mean operative time was 100 ± 20 minutes, mean hospitalization length stay was 3 ± 2.3 days. No major complications occurred. Followed from 3 to 36 month are favorable with good outcome in 88%, average in 10%, poor in 2%. Conclusion: Retroperitoneal laparoscopic surgery is safe and feasible procedure in children with urinary anomalies.
