ABSTRACT
Currently, the total ureteral avulsion are mainly secondary to ureteroscopy, and it is rarely caused by uterine evacuation clinically. This paper reported a case of total ureter avulsion after uterine evacuation, treating by ileal replacement for ureter under general anesthesia, and the surgical outcome was good. Uterine evacuation is a routine, less risky procedure, but it also can lead to serious complications such as total ureteral avulsion or bladder rupture. For potential high-risk patients with uterine evacuation, preventive measures such as accurate localization under B-ultrasound guidance or pre-operative ureteral stents indwelling are useful to avoid the occurrence of such serious complications. If total ureteral avulsion occurs, ileal replacement for ureter is a viable and effective treatment.
ABSTRACT
Objective To explore the availability and safety of ileal ureter replacement combined with ileal augmentation cystoplasty in treating ureteral stenosis with contracted bladder.Methods From August 2015 to November 2018,three patients who underwent ileal ureter replacement combined with augmentation cystoplasty were treated with ileal ureter replacement combined with augmentation cystoplasty.There were 1 male and 2 females with the age ranging from 34 to 55 years (mean 39 years).Two patients suffered from left ureter stenosis,and one patient had stenosis on the both sides.The length of the ureter stenosis ranged from 6 to 18 cm (mean 9.8 cm).The preoperative bladder capacity ranged from 60 to 150 ml (mean 103.3 ml).In the surgery,part of ileum was used to replace the ureter,and the distal intestine was made into U-shape to enlarge the bladder.Results All operation were completed successfully.The operation time ranged from 220 to 400 min (mean 303.0 min),and the blood loss ranged from 150 to 500 ml (mean 283.3 ml).Laparoscopic surgery was performed in 1 case and open surgery in 2 cases.Three weeks after the surgery,the bladder volume underwent cystography ranged from 300 to 400 ml (mean 360.0 ml).Three months after the surgery,the postvoid residual urine volume ranged from 20 to 50 ml (mean 33.3 ml).Postoperative frequency and urgency of urine were completely relieved in 1 case,alleviated in 2 cases.Flank pain was completely relieved in 1 case,and alleviated in 2 cases postoperatively.The serum creatinine of 2 patients mildly increased after the surgery,while 1 patient remained stable.For complications,1 patient had urinary infection,and 1 patient suffered from metabolic acidosis.Conclusions Ileal ureteral replacement combined with augmentation cystoplasty can be the choice of treatment for long segment ureteral stenosis and enlarge the bladder simultaneously.The postoperative complications and the kidney functions should be regularly followed up.
ABSTRACT
Ileal ureter is a suitable treatment option for patients with long ureteric strictures. Minimally invasive techniques have been shown to be as safe as open techniques but superior in terms of lesser trauma, less bleeding and less postoperative recovery time. In order to evaluate the feasibility and clinical efficacy of laparoscopic ileal ureter replacement, review of related literatures, indications, contraindications, surgical method, postoperative results combined with experience of our center has been done. Total 20 cases of laparoscopic ileal ureteral operation have been reviewed, the mean operation time was 195480 and blood loss was 50 ～ 375 ml and 7 Robotic ileal ureter replacement were reviewed median surgery time was 320720 min and bleeding is less then 10 ml100 ml. The operation complications include urinary leakage, intestinal obstruction, anastomotic site leakage, transient azotemia, urinary tract infection and so on. Postoperative renal function of all patients was improved in different degrees. Laparoscopic and Robotic ileal ureter replacement is feasible and can be used as an effective treatment for long ureteral injuries, although the curative effect is same as that of traditional open surgery, but Comparatively laparoscopic and robotic postoperative morbidity is less and have advantages such as it reduces surgical trauma, intraoperative bleeding, postoperative complications, less surgical scar and recovery time.The cases in the reports are limited, more cases need to be studied, and long-term results need to be assessed to establish and standardize these technique.
ABSTRACT
Objective To report a ileal ureteric replacement surgery for bilateral long segment ureter injury.Methods Data from a patient suffered bilateral long segment uretercic stenosis was reviewed.A 32-year-old female,who underwent radical surgery of cervical cancer and postoperative radiotherapy 1 year ago,complained intermittent low back pain for 11 months and was found renal function abnormality for 3 months.Ultrasound showed bilateral hydronephrosis,and the CT urography showed bilateral middle-lower ureteral stenosis.Preoperative diagnosis was bilateral hydronephrosis with bilateral ureteral obstruction.The patient underwent bilateral ileal ureteric replacement under general anesthesia.Results The surgical procedure was successful and the postoperative recovery was favorable.The operation time was 180 min,and blood loss was 100 ml.The abdominal cavity drainage tube was removed 8 days and the urinary catheter was removed 9 days postoperatively.During 8 months' follow up,the patient showed resolved flank pain with stable serum creatinine.No complication was reported.The CTU 2 months postoperatively showed the hydronephrosis was relieved with normal functioning kidneys.Conclusion Bilateral ileal ureteric replacement surgery might be an effective procedure and viable option for bilateral long segment ureteric injuries.
