Urinary catheter alleviation navigator protocol (UCANP): Overview of protocol and review of initial experience.

BACKGROUND: Given the associated morbidity, mortality, and financial consequences of catheter associated urinary tract infections (CAUTIs), efforts should be made to mitigate the risk. We sought to describe, and report results for a post-catheter removal bladder management protocol focused on decreasing catheter reinsertion, catheter days, and overall CAUTI risk. METHODS: This was a quality improvement initiative implemented over a 3-month period at a single urban, tertiary health care center. Patients with an indwelling urinary catheter deemed eligible for removal were followed and cared for according to the study protocol. Rates of catheter reinsertion, catheter days, and assessment of CAUTI risk were compared between cohorts. RESULTS: A total of 173 patients were eligible for protocol enrollment. Catheter reinsertion rate was 16% during the pilot, compared to 21% and 27% for the historical cohorts, (P = .02). The mean number of catheter day's during the study was 1.4 days, compared to 9.5 and 5.6 days in the historical cohorts (P = .004). Catheter hours (OR 1.010 95% CI 1.005 - 1.015 P < .0001.) was a predictor of catheter reinsertion during the pilot. CONCLUSIONS: Our protocol resulted in a reduction of catheter reinsertion rates and number of catheter days. Expansion of this protocol to a larger patient cohort is required.

Description of Surgical Technique and Oncologic and Functional Outcomes of the Precision Prostatectomy Procedure (IDEAL Stage 1-2b Study).

BACKGROUND: The existing treatment options for men with intermediate- or high-volume low-risk prostate cancer (PCa) are associated with a substantial risk of over- or undertreatment. The development of risk-adjusted therapies is an unmet need for these patients. OBJECTIVE: To describe our novel technique of precision prostatectomy, a form of surgical focal therapy that allows radical excision of the index PCa lesion along with >90% prostatic tissue extirpation while preserving the prostatic capsule and seminal vesicle/vas deferens complex on the side contralateral to the dominant cancer lesion, and to report on medium-term functional and oncologic outcomes in the first 88 consecutive men who underwent this procedure between December 2016 and January 2020. DESIGN, SETTING, AND PARTICIPANTS: Men with (1) prostate-specific antigen (PSA) ≤20 ng/ml, (2) clinical T stage ≤cT2, (3) a dominant unilateral lesion with Gleason ≤ 4 + 3 disease with any number or percentage of cores involved ipsilaterally on prostate biopsy, (4) no primary Gleason ≥4 lesion contralaterally, and (5) a preoperative Sexual Health Inventory of Men (SHIM) score of ≥17 (out of 25) with/without phosphodiesterase type-5 inhibitor use who consented to undergo precision prostatectomy were included in this single-arm, single-center, IDEAL stage 2b prospective development study. INTERVENTION: Robotic precision prostatectomy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The safety and urinary, sexual, and oncologic outcomes of the precision prostatectomy technique were studied. Descriptive statistics and Kaplan-Meier analyses were used to assess 12-mo urinary continence (0-1 pad), 12-mo sexual potency (SHIM score ≥17), 36-mo freedom from clinically significant PCa (grade group ≥2), secondary treatments, metastatic disease, and mortality. RESULTS AND LIMITATIONS: At study entry, the median age, PSA, and SHIM score were 60.0 yr (interquartile range [IQR] 54.2-65.9), 5.7 ng/ml (IQR 4.2-7.1), and 22 points (IQR 19-24), respectively. The median follow-up was 25 mo (IQR 14-38). At 12 mo, all patients were continent (0-1 pads), with 90.9% of patients using 0 pads. The median time to urinary continence was 1 mo (IQR 1-4). At 12 mo, 85% of all-comers and 90.2% of the preoperatively potent men were potent. The median time to sexual potency was 4 mo (IQR 4-12). From an oncologic standpoint, at 36 mo an estimated 93.4% of the patients were free from clinically significant residual PCa and 91.7% had not undergone any additional treatment. All patients were alive and free of metastatic disease at 36 mo. CONCLUSIONS: Precision prostatectomy is technically safe and reproducible and offers excellent postoperative functional results. At 36-mo follow-up, the oncologic outcomes and secondary treatment rates appear to be superior to existing ablative focal therapy results. Pending long-term data, a risk-stratified surgical approach to PCa may avoid whole-gland therapy and preserve functional quality of life in men with localized PCa. PATIENT SUMMARY: Precision prostatectomy is a new form of focal therapy for intermediate-risk prostate cancer in which a 5-10-mm rim of prostate capsule is left on the opposite side of the gland to where the dominant cancer is located. The technique appears to be safe and efficacious and adds to the growing armamentarium of risk-adapted therapies for treatment of localized prostate cancer that avoid the adverse effects on urinary and erectile function of whole-gland treatments.

Association of lymph node yield with overall survival in patients with pathologically node negative prostate cancer.

We investigated the association between lymph node yield (LNY) with overall survival (OS) and post-radical prostatectomy (RP) secondary treatments among men with pathologically node negative (pN0) prostate cancer. We reviewed the National Cancer Database for men with Gleason Grade Group 2 or higher prostate cancer treated with RP and had pathologically node-negative disease. LNY was modeled as a continuous and categorical variable grouped by quartiles of LNY. Secondary treatment was defined as the use of radiation or systemic therapy post-RP. Multivariable Cox proportional hazards and logistic regression models were used to test for an association of LNY with OS and secondary treatments, respectively. We identified 89,416 men with pN0 prostate cancer treated with RP from 2010-2015. LNY was associated with improved OS when modeled as a categorical and continuous variable. The third (6-9 nodes) and fourth (≥10 nodes) quartiles of LNY were associated with improved OS (HR 0.87, 95% CI 0.79-0.96, P = 0.006 and HR 0.88, 95% CI 0.79-0.98, P= 0.017, respectively) when compared with the lowest quartile of LNY (≤3 nodes) and the hazard of death decreased by 1% for each benign lymph node removed (HR 0.99, 95% CI 0.98-0.99, P= 0.022). Additionally, categorical and continuous LNY was associated with significantly less use of post-RP secondary treatments. Removal of additional negative lymph nodes was associated with improved OS and less secondary treatments in patients with pN0 prostate cancer. These data suggest that removing a higher quantity of lymph nodes provides more accurate staging and prognosis.

Robotic Kidney Transplantation with Regional Hypothermia versus Open Kidney Transplantation for Patients with End Stage Renal Disease: An Ideal Stage 2B Study.

PURPOSE: We report on comparative effectiveness of minimally invasive versus traditional open kidney transplantation. MATERIALS AND METHODS: We undertook a prospective cohort study of 654 patients who underwent open or robotic kidney transplantation at a single tertiary care hospital between January 2013 and December 2015. Primary outcome was delayed graft function, defined as the need for dialysis within 1 week of surgery. Secondary outcomes included postoperative complications, pain, graft rejection, and graft and patient survival. Nonparsimonious propensity score and Ding-VanderWeele analytical methods were used to account for confounding bias. RESULTS: Within the 1:3 matched cohort (robotic 126, open 378; well matched with standardized mean difference ∼10%), the robotic approach was associated with lower rates of wound infections (0% vs 4%, p=0.023) and symptomatic lymphoceles (0% vs 7% at 36 months, p=0.003), as well as reduced postoperative pain, requirement for narcotic analgesia and blood loss. There were no differences between the 2 groups, robotic versus open, with respect to graft function (delayed graft function 0% vs 2.4%, p=0.081), hospital stay (median 8 days for both, p=0.647), graft rejection (16.2% vs 18.6% at 36 months, p=0.643), and graft (95.2% vs 96.3% at 36 months, p=0.266) and overall survival (94.5% vs 98.1% at 36 months, p=0.307). Ding-VanderWeele analysis suggested minimal influence of unknown confounders on study findings. CONCLUSIONS: Robotic kidney transplantation with regional hypothermia was associated with a lower rate of postoperative complications and improved patient comfort in comparison to open kidney transplantation. Graft function, and graft and overall survival were comparable between the 2 techniques.
