Background: Endoscopic surgery is now increasingly taking the place of open surgery in urology. Traditionally, endourological procedures are classified as clean-contaminated because the genitourinary tract is colonized by micro-flora, even in the case of sterile urine. The aim of this study was to determine whether a difference occurs in the infection rate after short endourological procedures using standard scrubbing and partial scrubbing techniques before the operations. Patients and Methods: This was a retrospective analysis of 397 patients who underwent a short endourological procedure, with all procedure durations lasting <30 min. Patients were divided into a first group who underwent operations using a full-scrub technique and a second group who underwent operations using a partial-scrub technique. All patients were followed up for the occurrence of urinary tract infections (UTIs). Both groups were compared for age, gender, and post-operative development of UTIs. Values of p < 0.05 were considered statistically significant. Results: Of the 397 patients, 200 and 197 underwent their procedures using the full-scrub and partial-scrub techniques, respectively. Females and males accounted for 142 (35.8%) and 255 (64.2%) patients, respectively. Only 18 (4.5%) patients developed documented UTIs and antibiotics were prescribed. Of the 18 patients diagnosed with post-operative UTIs, 10 (55.5%) had undergone partial-scrub operations and 8 (45.5%) had undergone full-scrub operations (p = 0.638). Conclusion: Our findings did not indicate any significant relationship between the risk of developing UTI after a short endourological procedure and the scrub technique used before the operation (partial or full scrub).

OBJECTIVE: The preoperative scrub has been shown to lower the incidence of surgical site infections (SSIs). Various scrubbing and gloving techniques exist; however, it is unknown how specific scrubbing technique influences SSI rates in neurosurgery. The authors aimed to assess whether the range of scrubbing practice in neurosurgery is associated with the incidence of SSIs.
METHODS: The authors conducted a retrospective review of a prospectively maintained database to identify all 90-day SSIs for neurosurgical procedures between 2012 and 2017 at one of their teaching hospitals. SSIs were classified by procedure type (craniotomy, shunt, fusion, or laminectomy). Surveys were administered to attending and resident physicians to understand the variation in scrubbing methods (wet vs dry, iodine vs chlorhexidine, single vs double glove). The chi-square followed by multivariate logistic regression analyses were utilized to identify independent predictors of SSI.
RESULTS: Forty-two operating physicians were included in the study (18 attending physicians, 24 resident physicians), who performed 14,200 total cases. Overall, SSI rates were 2.1% (296 SSIs of 14,200 total cases) and 2.0% (192 of 9,669 cases) for attending physicians and residents, respectively. Shunts were independently associated with an increased risk of SSI (OR 1.7 [95% CI 1.3-2.1]), whereas laminectomies were associated with a decreased SSI risk (OR 0.4 [95% CI 0.2-0.8]). Wet versus dry scrub (OR 0.9 [95% CI 0.6-1.4]), iodine versus chlorhexidine (OR 0.6 [95% CI 0.4-1.1]), and single- versus double-gloving (OR 1.1 [95% CI 0.8-1.4]) preferences were not associated with SSIs.
CONCLUSIONS: There is no evidence to suggest that perioperative infection is associated with personal scrubbing or gloving preference in neurosurgical procedures.
