AIM:To show the relationship of lumbar intervertebral discs with the ureters by using computerized tomography (CT). MATERIAL and METHODS:Eighty patients (male/female: 42/38) with a mean age of 45 years were included in this retrospective study. An imaginary line passing through the tangential to the posterior cortex of the vertebral body was drawn at the intervertebral disc level (line a). Perpendicular to this line were two lines (line b) drawn from the ureters.The lines of the cortex, where "line a" was cut (point c), were also drawn from the contralateral ureter (line d). The distances between "lines b and d" were measured. Another line was drawn from both "c" points to the ipsilateral ureters (line x). The angle between "lines a and x" was measured (angle x). RESULTS:The right kidney hilus was inferior to the left kidney hilus. A significant negative correlation was observed between line band lumbar level (r=−0.95). The average length of "line b" at the lower lumber levels was 2.1 cm. Moreover, a positive correlation was found between "angle x" and lumbar level (p<0.05). The "angle x" increased from 38° to 80° with the decrease in lumbar levels. In addition, the "angle x" was significantly higher in male patients (p<0.05) than in female patients. No significant correlation was found between "line d" and lumbar level. CONCLUSION:CT is an illumination modality that could elucidate the relationship between intervertebral disc and ureter preoperatively and could visualize the retroperitoneum.

“…Although intra-operative identification and repair of ureteral injuries is associated with better outcomes, 50%–70% of these lesions are missed in acute settings [ 7 ]. Patients with unrecognized injuries can show abdominal pain, fever, anuria, peritonitis, and even vaginal urinary leaking [ 8 ].…”

Diagnostic and Interventional Radiology Management of Ureteral Iatrogenic Leakage after Gynecologic Surgery

Objective: To report safety and efficacy of interventional radiology procedures in the treatment of gynecologic iatrogenic urinary leaks. Methods: A retrospective analysis of iatrogenic ureteral lesions treated between November 2009 to April 2019 was performed. Under ultrasound (US) and fluoroscopy guidance, an attempt to place a ureteral stent and nephrostomy was carried out in the same session using an anterograde percutaneous approach. At the end of any procedure, a fluoroscopic control and a cone-beam CT scan (CBCT) were performed to check the correct placement and functioning of the nephrostomy and DJ stent. In cases of difficult ureteral stent placement via the single anterograde approach, the collaboration of urologists was requested to perform a rendezvous technique, combined with the retrograde approach. Results: DJ stent placement was achieved using the anterograde approach in 12/15 (80.0%) patients and using the retrograde approach in 3/15 cases (20.0%). Moreover, in 3/15 (20.0%) patients, surgical treatment was needed: in one case because of the persistence of ureteral stenosis at 6 months, and in the other two cases due to ureter-vaginal fistula. No major complications were recorded; overall, minor complications occurred in 4/8 patients. Conclusion: Percutaneous minimally invasive treatment of iatrogenic ureteral lesions after gynecological surgery is a safe and effective option.

To present our experience with laparoscopic ureteroneocystostomy with bladder flap (LUCBF) for treating benign ureteral stenosis and evaluate its feasibility and efficacy. The clinical data of 27 patients with benign ureteral stenosis who underwent LUCBF were retrospectively analyzed. After identification and excision of the ureteral stenosis segment, the healthy ureteral stump was dissected and incised longitudinally. A U-shaped or spiral bladder flap was harvested from the anterolateral bladder wall for ureteroplasty. All patients underwent LUCBF successfully, including 14 patients were combined with psoas hitch technique, between 90 and 220 min (median, 155 min). The median length of ureteral defect was 6 cm (range, 5–17 cm). The median blood loss was 40 ml (20–150 ml). The median indwelling time of double-J stent was 8 weeks (range, 4–8 weeks). Five patients (10.6%) suffered postoperative complications during the follow-up period (range, 12–48 months), including fever, hematuria, urinary tract infection and recurrent stenosis. The success rate was 96.3% (26/27). Patients with long ureter defects had longer operative time and more blood loss than short ureter defects. LUCBF was a safe and feasible technique for benign ureteral stenosis. Long ureter defect was related to longer operative time and more blood loss.
