Risk factors for and delayed recognition of genitourinary fistula following radical hysterectomy for cervical cancer: a population-based analysis

OBJECTIVE

This study aimed to identify the risk factors for genitourinary fistulas and delayed fistula recognition after radical hysterectomy for cervical cancer.

METHODS

This study was a retrospective analysis of data collected in the Major Surgical complications of Cervical Cancer in China (MSCCCC) database from 2004-2016. Data on sociodemographic characteristics, clinical characteristics, and hospital characteristics were extracted. Differences in the odds of genitourinary fistula development were investigated with multivariate logistic regression analyses, and differences in the time to recognition of genitourinary fistula were assessed by Kruskal-Wallis test.

RESULTS

In this study, 23,404 patients met the inclusion criteria. Surgery in a cancer center, a women's and children's hospital, a facility in a first-tier city, or southwest region, stage IIA, type C1 hysterectomy, laparoscopic surgery and ureteral injury were associated with a higher risk of ureterovaginal fistula (UVF) (p<0.050). Surgery in southwest region, bladder injury and laparoscopic surgery were associated with greater odds of vesicovaginal fistula (VVF) (p<0.050). Surgery at cancer centers and high-volume hospitals was associated with an increase in the median time to UVF recognition (p=0.016; p=0.005). International Federation of Gynecology and Obstetrics (FIGO) stage IIA1-IIB was associated with delayed recognition of VVF (p=0.040).

CONCLUSION

Intraoperative urinary tract injury and surgical approach were associated with differences in the development of UVFs and VVFs. Patients who underwent surgery in cancer centers and high-volume hospitals were more likely to experience delayed recognition of UVF. Patients with FIGO stage IIA1-IIB disease were more likely to experience delayed recognition of VVF.

[Fulminant Emphysematous Pyelonephritis Secondary to Urothelial Neoplasia with Reno-Colic Fistula]

The emphysematous pyelonephritis is a uncommon and potentially fatal entity. The recognition of this condition enables the early correct management of patients. Diabetes and ureteral obstruction are the main risk factors identified. We present the case of a patient with no relevant risk factors or prior medical history, in which the reason of admission to the emergency department was back pain, eventually evolving into septic shock in the early hours. The imaging tests identified the presence of peri-renal and subcutaneous gas which guided the medical team to the right diagnosis (emphysematous pyelonephritis secondary to fistulized urothelial neoplasia) and the optimal surgical treatment. However, in the post-operative period the patient died, as the clinical condition and laboratory test results performed during the admission were predicting. It should also be mentioned that this same case illustrated a bacteraemia by Sphingomonas Paucimobilis (acquired in the community) with cavitated damage to lungs (probable septic embolism).

Postoperative Ureteral Leak Treated Using a Silicone-Covered Nitinol Stent

Ureteral fistula is a serious complication of abdomino-pelvic surgeries, often resulting in poor outcomes owing to lack of proper treatment. We report the case of a 49-year-old woman who underwent placement of a silicone-covered ureteral occlusion stent in her right ureter for the management of ureteral leakage after pelvic surgery. A ureterogram obtained 18 months following the stent placement confirmed that there was no stent migration or additional urine leakage. We propose that the silicone-covered ureteral occlusion stent is practical, fast, and safe for the management of ureteral leakage.

Three distinct urethral fistulae 35 years after pelvic radiation

Introduction:

While the development of fistulae is a well-known complication of radiotherapy, such fistulae can often be challenging to manage.

Case Presentation:

We describe the case of a 37 year old male who developed in succession a urethrocutaneous fistula to the thigh, a rectourethral fistula and a peritoneo-urethral fistula 35 years after radiotherapy for pediatric pelvic rhabdomyosarcoma. These complications were managed successfully after multiple surgical procedures.

Discussion:

We subsequently discuss the different approaches currently employed for the management of radiation induced urinary fistulas and describe the rationale behind our approach towards their surgical management.

Pyeloduodenal fistula successfully treated by endoscopic ligation without surgical nephrectomy: case report

A 74-yr-old woman presented with fever and abdominal discomfort. She was in a septic condition caused by urinary tract infection. Her computed tomogram of the abdomen revealed features of hydronephrosis with ureteral stones in both kidneys. During percutaneous nephrostomies, right pyeloduodenal fistula (PDF) was diagnosed. Elective surgery was originally planned but the patient was in a poor condition to undergo surgery. Instead, 2 times endoscopic clipping and ligation by endoloop were applied with parenteral antibiotics for the fistula lesion. On admission day 30, she was discharged from the hospital after confirmation of no more contrast leakage on fistulography. We reviewed the literature and discuss the etiologies, clinical presentations, diagnosis, and treatment of PDF.

Renocolic fistula secondary to a perinephric abscess: a late complication of a forgotten double J stent

Late complications of ureteral stents are frequent, and longer indwelling times are associated with an increased frequency of complications. Although there are reports of various complications of long-term indwelling ureteral stents, a renocolic fistula secondary to a perinephric abscess resulting from an indwelling ureteral stent has not been reported. Here, we present a fatal case of a renocolic fistula secondary to a perinephric abscess caused by an encrusted forgotten double J stent in a functionally solitary kidney.
