Prise en charge d’une rétention aiguë d’urine

Urine drainage management in colorectal surgery

INTRODUCTION

Enhanced recovery programs (ERP) is aimed at reducing a patient's surgical stress response, specifically by reducing the duration of catheterization. In cases of colorectal surgery, there is pronounced heterogeneity in urinary catheterization, which is largely explained by fear of acute urinary retention (AUR).

OBJECTIVE

The objective of the work is to report on the current literature on postoperative urinary catheterization following colorectal surgery, particularly with regard to the risk of AUR, and thereby contribute to the standardization of perioperative practices.

RESULTS

In colon surgery without preoperative urinary disorders, catheterization must not exceed 24h. In rectal surgery, catheter removal starting on postoperative D2 seems reasonable in the absence of AUR risk factor (RF). Male sex, past history of lower urinary tract obstruction, abdomino-perineal amputation (APA) and low rectal anastomosis are AUR risk factors that must be taken into account when deciding to withdraw the urinary catheter. While the role of a suprapubic catheter is not clearly defined, it may be of use following APA. The epidural catheter is another AUR risk factor, but it seems possible to withdraw the urinary catheter on postoperative D1, before the epidural catheter, provided that the other risk factors have been taken into full account. Lastly, up until now no satisfactorily conducted study has assessed the prophylactic value of systematic perioperative alpha-blocker treatment in colorectal surgery.

Evaluation of the impact of a clinical pathway on the progression of acute urinary retention

AIMS

The management of acute urinary retention (AUR) revolves around trial without catheter (TWOC) after prescription of an alpha-blocker. This study evaluates the implementation of a clinical pathway for AUR.

METHODS

Specific clinical pathways for AUR was established between the Emergency Department and the Department of Urology in order to reduce the duration of bladder drainage that included standard prescriptions, an information sheet, and a note to be faxed to scheduling nurses to organize the trial without catheter (TWOC). The main endpoint was the reduction in the time between the AUR episode and TWOC, without decreasing urination.

RESULTS

Between April 2015 and December 2016, 248 patients were treated in the Emergency Department, and externally, for AUR. One hundred and seventy patients were enrolled in the pathway group and 78 in the control group. The mean duration of urinary catheterization decreased by 5.5 days as did the number of patients lost to follow-up (32% vs 76%), without decreasing the successful voiding (46% vs 36%). The duration of the urinary catheterization was not related to the chance of successful voiding regardless of the urine volume and a drainage time of over 10 days significantly reduced the chance of success (68%, n = 26 versus 42%, n = 76; P = 0.0038).

CONCLUSION

The implementation of a clinical pathway for AUR reduced the number of patients lost to follow-up and the catheterization duration, thus optimizing the management of these patients.

[Epidemiology of emergency consultations for acute urine retention]

INTRODUCTION

Acute urinary retention (AUR) is a common reason for emergency consultation. It may be spontaneous or precipitated and affects both men and women. The purpose of this study was to determine the profile of men visiting emergency departments for an AUR.

MATERIEL AND METHODS

A retrospective monocentric study including all men who consulted the emergency department between January 2014 and December 2016 for AUR was conducted.

RESULTS

In 3 years, 731 patients were admitted for AUR (611 men and 120 women). The mean age was 71.6±14 years with a mean retention volume of 948±668mL drained for 96% of patients (n=584) through a bladder catheter and 4% (n=27) with a suprapubic catheter. Most patients had an urological (66%, n=104) or neurologic (40%, n=242) history and 23% (n=136) already had an episode of AUR. In 28% of cases (n=173), the globe was not painful. A majority of AUR were spontaneous, 53% (n=326) versus 46% (n=279) who were precipitated, secondary to a recent surgical procedure (<1 month) (15%, n=89), hematuria (9%, n=54), or male urinary tract infections (7%, n=42). Patients were treated externally in 71% (n=436), 25% (n=153) were hospitalized with significantly more comorbidities.

CONCLUSION

Men consulting emergency for AUR are 72 years old, with a globe volume of 942mL. Thirty-three percent have a history of BPH, with a prostate treatment like alpha-blockers type. Almost all patients were treated with a bladder catheter and the majority was treated externally.
