Complex Foley Catheter Placement After Radical Prostatectomy.

OBJECTIVE: To describe a method for replacement of a dislodged critical urethral foley catheter following a robotic- assisted laparoscopic radical prostatectomy. BACKGROUND: Following robotic-assisted laparoscopic radical prostatectomy (RALP), a bladder drainage via catheter is necessary to allow for proper healing of the urethrovesical anastomosis. In most cases, this is done using a transurethral foley catheter.1,2 Early traumatic loss of the urethral catheter following RALP is consider a urologic emergency and can lead to vesicourethral anastomotic urine leak, ileus, infection or abscess, and future anastomotic stenosis.3 Replacing the urethral catheter in this situation can be difficult even in experienced hands and often requires imaging assistance. METHOD: A 53-year-old male with Grade Group 4 (Gleason 4 + 4) prostate cancer underwent an uncomplicated RALP. During his post-operative course, his urethral foley catheter fell out or was traumatically removed three times resulting in disruption of the posterior anastomosis. To replace the urethral catheter and prevent it from being dislodged again, a transabdominal approach under ultrasound and cystoscopic guidance was employed to replace the catheter into the bladder and secure it trans abdominally using a single G-tube safety Pexy T fastener. CONCLUSION: This case reports describes a technique used to replace and secure a urethral foley catheter in a patient who suffered from a posterior anastomotic disruption following repeated loss and traumatic removal of his urethral foley catheter during his RALP post-operative course. While replacement of a dislodged urethral foley catheter following a RALP can be challenging, the catheter can safely be placed and secured trans abdominally in these rare but serious situations where the conventional catheter secure devices and patient education alone are not sufficient to prevent removal.

Impact of radiation on the incidence and management of ureteroenteric strictures: a contemporary single center analysis.

BACKGROUND: Ureteroenteric stricture incidence has been reported as high as 20% after urinary diversion. Many patients have undergone prior radiotherapy for prostate, urothelial, colorectal, or gynecologic malignancy. We sought to evaluate the differences between ureteroenteric stricture occurrence between patients who had radiation prior to urinary diversion and those who did not. METHODS: An IRB-approved cystectomy database was utilized to identify ureteroenteric strictures among 215 patients who underwent urinary diversion at a single academic center between 2016 and 2020. Chart abstraction was conducted to determine the presence of confirmed stricture in these patients, defined as endoscopic diagnosis or definitive imaging findings. Strictures due to malignant ureteral recurrence were excluded (3 patients). Statistical analysis was performed using chi squared test, t-test, and Wilcoxon Rank-Sum Test, logistic regression, and Kaplan-Meier analysis of stricture by cancer type. RESULTS: 65 patients had radiation prior to urinary diversion; 150 patients did not have a history of radiation therapy. Benign ureteroenteric stricture rate was 5.3% (8/150) in the non-radiated cohort and 23% (15/65) in the radiated cohort (p = < 0.001). Initial management of stricture was percutaneous nephrostomy (PCN) in 78% (18/23) and the remaining 22% (5/23) were managed with primary retrograde ureteral stent placement. Long term management included ureteral reimplantation in 30.4% (7/23). CONCLUSIONS: Our study demonstrates a significant increase in rate of ureteroenteric strictures in radiated patients as compared to non-radiated patients. The insult of radiation on the ureteral microvascular supply is likely implicated in the cause of these strictures. Further study is needed to optimize surgical approach such as utilization of fluorescence angiography for open and robotic approaches.
