Abstract

To define the incidence and risk factors associated with rectourethral fistula (RUF) formation following primary whole-gland cryosurgery using a multicenter, centralized registry. The Cryo On-Line Data (COLD) registry was queried for men undergoing primary whole-gland cryotherapy between 1990 and 2014 who developed a RUF. Patient factors and disease parameters were correlated with RUF using Chi-square test and the t-test. Variables with P<0.25 were entered into a binary logistic regression with stepwise backward elimination to determine the factors associated with RUF formation. A total of 4,102 men underwent primary whole-gland cryotherapy, in the COLD registry at the time of analysis. Postoperative RUF was documented in 50 out of 4102 cases (1.21%). Patients with RUF had similar demographic data, prostate volume, preoperative prostate-specific antigen level and clinical stage in comparison to those without fistula. On both univariate and multivariate analyses, postoperative urinary retention (OR: 6.30; 95% CI 3.43-11.58, P<0.001), preoperative Gleason score of ≥7 (OR: 1.92; 95% CI 1.08-3.43, P=0.027) and preoperative incontinence (OR: 2.95, 95% CI 1.12-7.76, P=0.028) were the most signifiant risk factors associated with RUF formation. Primary whole-gland cryotherapy for prostate cancer is associated with a historically low rate (1.21%) of postoperative RUF formation. The rate decreased further to 0.55% over the last several years, suggesting better patient selection and technical improvement. Postoperative urinary retention, Gleason score > 7 and preoperative urinary incontinence were the key demographic, clinical and pathological features associated with RUF formation in this study.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 June 2018.
All research outputs
#8,650,074
of 13,799,368 outputs
Outputs from Journal of Endourology
#625
of 1,047 outputs
Outputs of similar age
#162,508
of 271,969 outputs
Outputs of similar age from Journal of Endourology
#17
of 23 outputs
Altmetric has tracked 13,799,368 research outputs across all sources so far. This one is in the 23rd percentile – i.e., 23% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,047 research outputs from this source. They receive a mean Attention Score of 3.5. This one is in the 21st percentile – i.e., 21% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 271,969 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 31st percentile – i.e., 31% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 23 others from the same source and published within six weeks on either side of this one. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
