Overall, shorter duration of indwelling catheter is associated with a decreased incidence of UTI

Multiple RCTs, each involving between 100 and 200 patients undergoing either Cesarean Section or other gynecologic surgery, demonstrate a significant decrease in UTI incidence with shorter time of indwelling catheter placement (Dobbs, Jackson, Wilson, Maplethorpe, & Hammond, 1997; Kamilya, Seal, Mukherji, Bhattacharyya, & Hazra, 2010; Liang, Lee, Chang, Wang, & Soong, 2009)

One RCT studying 134 women having vaginal prolapse surgery demonstrated a trend toward a higher, but not statistically significant, incidence of UTI two weeks post-operatively when catheter remained in for 24 vs. 3 hours after surgery (Glavind, K., Morup, Madsen, & Glavind, J., 2007)

One RCT involving 200 women undergoing scheduled, elective Cesarean Section found no statistically significant difference in UTI incidence between women whose catheter was removed immediately after surgery and those whose catheter remained in place for 24 hours (Onile, Kuti, Orji, & Ogunniyi, 2008

A descriptive, cross sectional study of 1438 women determined the incidence of UTI is directly correlated with duration of catheterization (Buchholz, Daly-Grandeau, & Huber-Buchholz, 1994)

Urinary retention is a potential complication of early catheter removal following Cesarean Section

While the risk is relatively small in most cases, it must be considered in decisions regarding when to remove an indwelling catheter after Cesarean Section. The risk ranges from 3.38% following removal of indwelling catheter in one descriptive study of 207 Cesarean Section patients (Chai, Wong, Mak, Cheon, Yip, & Wong, 2008) to 6.0% in a quasi-experimental study of 188 patients in which 133 patients had the catheter removed immediately after Cesarean Section (Arulkumaran, Cheng, Ingermarsson, Low, & Ratnam, 1986)

In one prospective cohort study looking at 44 women undergoing Cesarean Section with regional anesthesia, when volume of urine in the bladder was measured at the time of first sensation to void, the median volume present was 152.4 ml. The authors note even one episode of over-distention of the bladder can cause significant and possibly permanent injury, making this a problem of significance should it occur (Foon, Toozs-Hobson, Millns, & Kilby, 2010). These authors recommend a protocol for bladder management following early catheter removal is necessary to help prevent untreated urinary retention

In one RCT involving 270 patients, one half of the patients had no indwelling catheter placed either during or after their Cesarean Section. The incidence of urinary retention requiring post-operative catheterization was 4.4% (Ghoreishi, 2003)

Several studies indicate potential benefits for patients when no indwelling catheter is used either during or immediately following Cesarean Section

was approximately half that of when an indwelling catheter was used for 12 hours following surgery. The same study also found that hospital length of stay was shorter by almost 18 hours when no catheter was used

A large RCT comparing women in whom no catheter is used for Cesarean Section with those in whom catheter is removed 12 hours after surgery found that the incidence of UTIs was significantly lower in the no catheter group, as was mean time to ambulation (Nasr, ElBigawy, Abdelamind , Al-Khulaidi, Al-Inany, & Sayed, 2009). Additionally, hospital length of stay was significantly shorter in the non-catheterized group

One RCT of 200 women in which the catheter was removed immediately following Cesarean Section versus 24 hours after surgery found no statistically significant difference in either mean post-operative ambulation time or mean length of hospital stay (Onile, Kuti, Orji, & Ogunniyi, 2008)

Urinary  catheterization  is  the  leading  cause  of  hospital  acquired  urinary  tract  infections  (UTIs)   (Buchholz,   Daly-­‐Grandeau,   &   Huber-­‐Buchholz,   1994;     Niel-­‐Weise   &   Van   den  Broek,  2009).    Usual  practice  is  to  leave  an  indwelling  catheter  in  place  for  12-­‐24  hours  following  Cesarean  Section.    Concern  regarding  earlier  removal  of  the  catheter  is  related  to   potential   urinary   retention   following   regional   anesthesia   used   for   most   Cesarean  Sections.     As   a   result   of   recent   changes   in   the   Center   for   Medicare   Services   (CMS)  reimbursement   guidelines,   hospitals   will   no   longer   be   reimbursed   for   diagnosis,  treatment,  or  complications  associated  with  catheter-­‐acquired  UTIs  (CMS,  2008).  Nurses  caring   for   this   patient   population  are   in   a   position   to   impact   outcomes   related   to   the  utilization  and  management  of  urinary  catheters.

To determine if removal of indwelling catheter < 12 hours after a Cesarean Section involving regional anesthesia has an impact on the incidence of UTI or urinary retention.

Searched OVID Medline, CINAHL, and Essential Evidence Plus using a combination of the following terms: Cesarean Section, spinal anesthesia, urinary retention, UTIs, and urinary catheterization

Considered only studies involving women ages 19 to 44 years undergoing Cesarean Section or other gynecologic surgeries as primary procedure

Considered studies where women were not catheterized or received indwelling or intermittent urethral catheterization. Suprapubic catheterization was not considered

Utilized the following primary outcome criteria: incidence of UTI, urinary retention or both

Utilized the following inclusion criteria: RCTs, NRCTs, Systematic Reviews, Prospective/ Retrospective Quasi-Experimental Studies and Descriptive Studies. Individual Case Studies were not considered

Remove the indwelling catheter <12 hours following uncomplicated Cesarean Section in order to minimize the risk of UTI (B) Develop and implement guidelines for bladder management following early catheter removal to promote timely identification and management of urinary retention (B) More high-quality research is needed to study the most appropriate timing and criteria for early removal of catheter following Cesarean Section performed under regional anesthesia (B)
