[Results of conservative surgical management of ureteral injuries]

INTRODUCTION

The ureter is a retroperitoneal organ. Ureteral injuries are rare, with a prevalence of 0.083% of surgical interventions over 10 years. The objective of this study was to evaluate the surgical management of ureteric injuries according to the time of discovery, their size and their location. We also evaluated the results of this management on the renal repercussion as well as the predictive factors of the severity of the ureteric injuries.

MATERIAL AND METHODS

This was a monocentric retrospective study carried out on the basis of a systematic review of the CHU surgery files.

RESULTS

The average follow-up was 30 months. The average hospital stay was 8 days. Thirty-four patients (73.9%) underwent initial endoscopic management by attempting a double J probe. Only 20 patients received this double J probe and only 11 patients (55%) did not recidivate the ureteral injury with a median duration of maintenance of the double J probe of 90 days (28-240). Thirty-five patients received open surgical management (76.1%). We found 57% ureterovesical reimplantations (n=20), corresponding to pelvic ureteral injuries (n=32). We also found 20% of nephrectomies. No patient had recurrence of the ureteral injury. Eight patients had secondary dilatation of the pyelocalicious cavities (28.57%). The success of surgical treatment was therefore 57%.

CONCLUSION

The management of surgically treated ureter injuries provides good results but remains relatively diversified due to the different lesion levels. It was effective in 57% of cases including nephrectomies as failure of treatment.

[Endoscopic management of postoperative ureteral wound. Retrospective unicentric study from October 2003 to June 2014]

BACKGROUND

Ureteral wounds are rare with an incidence of 0.5 to 1% of pelvic surgeries. Their supports and their prognosis remain dependant of the period of support and the level of ureteral lesion. The importance of early treatment reduces morbidity and improves patient prognosis.

METHODS

A retrospective study from October 2003 to June 2014 was performed in a university hospital using a systematic chart review of patients' urology, digestive surgery, vascular surgery and gynecology.

RESULTS

Forty-six wounds were found in 43 patients. The majority of the ureteral wound was found at the pelvic ureter, i.e. 69.6% of the study population (n=32). The main cause was gynecological surgery (n=25). In the simple wound group, endoscopic treatment was effective in nearly 90% of cases (n=6). In the other two groups, the efficacy was only 30% and imposed a surgical treatment as second-line.

CONCLUSION

The management is based primarily on early detection or intraoperative, and on a correct initial knowledge of the location and size of the lesion. Endoscopic treatment can in most cases treated with a simple and minimally invasive operation an ureteral wound with nearly 90% success rate. In more complex wounds, endoscopy remains a step in the management with about 30% success rate in our study.
