The Urine Albumin-Creatinine Ratio and Kidney Function after Nephrectomy.
The Journal of urology
BACKGROUND: Patients with kidney cancer are at risk of developing chronic kidney disease (CKD) after radical and partial nephrectomy. We sought to determine if the urine albumin-creatinine ratio (UACR) is independently associated with progressive CKD after nephrectomy.METHODS: We performed a cohort study based within a large, integrated health care system. We identified patients who underwent radical or partial nephrectomy from 2004 to 2014 with UACR measured in the 12 months prior to surgery. We fit multivariable models to determine if the UACR was associated with the time to CKD progression (defined as reaching stage 4 or 5 CKD, eGFR <30 mL/min/1.73m2). We performed a parallel analysis measuring the time to stage 3b, 4 or 5 CKD (eGFR <45 mL/min/1.73m2) among patients with normal or near-normal preoperative kidney function (eGFR ≥60 mL/min/1.73 m2). We also examined the association between UACR and survival.RESULTS: 1930 patients underwent radical or partial nephrectomy and had preoperative UACR and pre- and post-operative eGFR. Of these, 658 (34%) and 157 (8%) had moderate (UACR 30-300mg/g) or severe albuminuria (UACR > 300mg/g), respectively. Albuminuria severity was independently associated with progressive CKD after radical (moderate albuminuria HR 1.7, 95%CI 1.4-2.2; severe albuminuria HR 2.3, 95%CI 1.7-3.1) and partial nephrectomy (moderate albuminuria HR 1.8, 95%CI 1.2-2.7; severe albuminuria HR 4.3, 95%CI 2.7-7.0). Albuminuria was also associated with survival following radical and partial nephrectomy.CONCLUSIONS: In patients undergoing radical or partial nephrectomy, the severity of albuminuria can stratify risk of progressive CKD.

Contemporary multicenter outcomes of continent cutaneous ileocecocystoplasty in the adult population over a 10-year period: A Neurogenic Bladder Research Group study.
Neurourology and urodynamics
Evidence is sparse on the long-term outcomes of continent cutaneous ileocecocystoplasty (CCIC). We hypothesized that obesity, laparoscopic/robotic approach, and concomitant surgeries would affect morbidity after CCIC and aimed to evaluate the outcomes of CCIC in adults in a multicenter contemporary study.We retrospectively reviewed the charts of adult patients from sites in the Neurogenic Bladder Research Group undergoing CCIC (2007-2017) who had at least 6 months of follow-up. We evaluated patient demographics, surgical details, 90-day complications, and follow-up surgeries. the Mann-Whitney U test was used to compare continuous variables and χ² and Fisher's Exact tests were used to compare categorical variables.We included 114 patients with a median age of 41 years. The median postoperative length of stay was 8 days. At 3 months postoperatively, major complications occurred in 18 (15.8%), and 24 patients (21.1%) were readmitted. During a median follow-up of 40 months, 48 patients (42.1%) underwent 80 additional related surgeries. Twenty-three patients (20.2%) underwent at least one channel revision, most often due to obstruction (15, 13.2%) or incontinence (4, 3.5%). Of the channel revisions, 10 (8.8%) were major and 14 (12.3%) were minor. Eleven patients (9.6%) abandoned the catheterizable channel during the follow-up period. Obesity and laparoscopic/robotic surgical approach did not affect outcomes, though concomitant surgery was associated with a higher rate of follow-up surgeries.In this contemporary multicenter series evaluating CCIC, we found that the short-term major complication rate was low, but many patients require follow-up surgeries, mostly related to the catheterizable channel.

Quadruple immunotherapy of Bacillus Calmette-Guérin, interferon, interleukin-2, and granulocyte-macrophage colony-stimulating factor as salvage therapy for non-muscle-invasive bladder cancer.
2017; 35 (12): 670.e7–670.e14
Bacillus Calmette-Guérin (BCG) is the most effective initial intravesical therapy for high-grade non-muscle invasive bladder cancer, but many patients still fail. Combination intravesical BCG and interferon (IFN) will salvage some patients but results remain suboptimal.We hypothesized that further immunostimulation with intravesical interleukin-2 and subcutaneous granulocyte-macrophage colony-stimulating factor may improve response to intravesical BCG and IFN in patient with prior BCG failure(s).A retrospective review was performed. Patients received 6 treatments of quadruple immunotherapy (intravesical solution with one-third dose BCG, 50 million units IFN, and 22 million units interleukin-2, along with a 250-mcg subcutaneous sargramostim injection). Surveillance began 4 to 6 weeks after treatment completion. Patients received maintenance if recurrence-free. Success was defined as no recurrence (bladder or extravesical) and bladder preservation. Analysis was performed by Kaplan-Meier method (P<0.05).Fifty-two patients received treatment with a median recurrence follow-up of 16.3 months and overall follow-up of 41.8 months. All patients had at least 1 prior BCG failure and 13% had 2 or more prior failures. Only 3 patients (6%) were unable to tolerate full induction. Treatment success was 55% at 1 year, and 53% at 2 years. Thirteen patients (25%) underwent cystectomy at a median time of 17.3 months with disease progression to T2 in 1 patient and T3 in 2 patients. No patients had positive surgical margins or positive lymph nodes.In patients with non-muscle-invasive bladder cancer with prior BCG failure, quadruple immunotherapy demonstrated good treatment success in some patients and warrants further evaluation.

Experience with Sequential Intravesical Gemcitabine and Docetaxel as Salvage Therapy for Non-Muscle Invasive Bladder Cancer
CURRENT UROLOGY REPORTS
2016; 17 (5): 38
Patients with high-grade muscle invasive bladder cancer (NMIBC) receive intravesical therapy with bacillus Calmette-Guérin (BCG) as the well-established standard-of-care. However, even with prompt induction of intravesical therapy, approximately 40 % of patients will recur within 2 years. For patients who fail BCG, options include radical cystectomy, repeat BCG therapy, or alternative intravesical salvage therapy. In this review, we will discuss the most recent published evidence on salvage intravesical therapy with an emphasis on a more in-depth report of our therapeutic strategy with sequential gemcitabine and docetaxel intravesical therapy for this treatment-refractory population. In addition, we will provide practical advice on our approach to this challenging patient population including the use of operative staging to aid early identification of treatment failures.
