Abstract Introduction: Although prostate cancer is the most common non-cutaneous cancer in men, it is traditionally diagnosed with a non-targeted, systematic transrectal ultrasound prostate biopsy (TRUS-Bx). This technique has been demonstrated to both under-detect clinically significant (CS) cancer and over-detect clinically insignificant cancer, and performs poorly in patients with a prior negative biopsy. With recent advances in MRI technology, most prominently the advent of multiparametric MRI, MRI-targeted prostate biopsy (MRI-TB) has been gaining favor as a more accurate alternative to TRUS-Bx. In this review, we attempt to summarize the current literature on MRI-TB and to determine if… More >

Abstract Introduction: To determine if a povidone iodine rectal preparation (PIRP) reduces rates of bacteriuria and bacteremia following transrectal ultrasound guided prostate needle biopsy (TRUS PNB).
Materials and methods: Men undergoing TRUS PNB were prospectively enrolled in a study comparing the impact of PIRP versus standard of care (two pills of ciprofloxacin 500 mg). Urine, blood, and rectal cultures were obtained 30 minutes post-procedure with colony forming units (CFUs) determined after 48 hours. Patients were called 7 and 30 days post-procedure to evaluate for infections.
Results: A total of 150 men were accrued into this study including 95 receiving… More >

Abstract Introduction: Patient decision-making aids (PDMAs) help patients make informed healthcare decisions and improve patient satisfaction. The utility of PDMAs for patients considering treatments for urolithiasis has not yet been published. We report our experience using PDMAs developed at our institution in the outpatient clinical setting in patients considering a variety of treatment options for stones.
Materials and methods: Patients with radiographically confirmed urolithiasis were given PDMAs regarding treatment options for their stone(s) based on their clinical profile. We assessed patients' satisfaction, involvedness, and feeling of making a more informed decision with utilization of the PDMAs using a… More >

Abstract Introduction: To investigate the use of a high-arginine immunonutrient supplement prior to radical cystectomy for bladder cancer.
Materials and methods: We recruited 40 patients to consume a total of four high-arginine immunonutrient shakes per day for 5 days prior to radical cystectomy. The primary outcome measures were safety, tolerability and adherence to the supplementation regimen. Ninety-day postoperative outcomes were also compared between supplemented patients and a cohort of 104 prospectively identified non-supplemented radical cystectomy patients. Multivariable logistic regression models were used to compare overall complications, infectious complications, and readmission rates between groups.
Results: There were no serious adverse… More >

Abstract Introduction: Lower urinary tract symptoms and retention are known complications of radiation for prostate cancer and traditionally transurethral resection of the prostate (TURP) has been avoided in these patients because of the risk of incontinence. The purpose of this study was to evaluate the incidence and predictors of post-TURP incontinence in previously radiated patients.
Materials and methods: One-hundred and eleven patients who underwent brachytherapy or external beam radiotherapy for prostate cancer with subsequent TURP performed between 1992 and 2012 at a single institution were identified. We tested for associations between post-TURP continence status and pre-TURP predictors including… More >

Abstract Introduction: Shared decision making (SDM) is widely encouraged by both the American Urological Association and Choosing Wisely for prostate cancer screening. Implementation of SDM is challenging secondary to time constraints and competing patient priorities. One strategy to mitigate the difficulties in implementing SDM is to utilize a decision aid (DA). Here we evaluate whether a DA improves a patient's prostate cancer knowledge and affects prostate-specific antigen (PSA) screening rates.
Materials and methods: Patients were randomized to usual care (UC), DA, or DA + SDM. Perception of quality of care was measured using the Consumer Assessment of Healthcare… More >

Abstract Introduction: We aimed to introduce our technique describing the removal of a chronic implanted tined-lead in patients with a sacral neuromodulator implant.
Materials and methods: We performed a retrospective review of patients who had chronic sacral neuromodulator (InterStim) implanted by a single surgeon from 2001 through 2015. This simple surgical technique was developed and successfully performed to remove the leads. Primary reasons for removal were elective due to poor symptoms control and failure to maintain response or lead migration. Patient demographics, indication for implantation, as well as installation and removal complications were recorded and analyzed.
Results: Twenty-five patients… More >

Abstract Introduction: This study aims at analyzing the impact of reaching current markers of proficiency on intra and postoperative clinical outcomes of laser vaporization with 180W GreenLight XPS in the treatment of benign prostatic hyperplasia.
Materials and methods: A retrospective analysis was conducted on a prospectively collected database of 328 consecutive patients who underwent photoselective vaporization of the prostate (PVP) using Greenlight XPS performed by a single experienced laser surgeon. A logarithmic model was used to evaluate the case number to attain benchmark criteria for durable treatment. We compared clinical outcomes before and after current markers of proficiency,… More >

Abstract Emphysematous cystitis is a rare type of urinary tract infection that is characterized by air pockets within the bladder wall and lumen, which come from gas that is mainly produced by gram-negative bacteria, notably Escherichia coli. This infection is more common in older women with poorly controlled diabetes. An abdominal computerized tomography (CT) scan is the gold standard method to make the diagnosis. The infection can be life-threatening, so prompt treatment is essential.
We present a case of a 39-year-old woman with poorly controlled type 2 diabetes who developed emphysematous cystitis after a bilateral adrenalectomy. The More >

Abstract Gross hematuria is a common occurrence in adults. The differential diagnosis is extensive, including: malignancy, trauma, infammation of the urinary tract, and stones. While, urinary tract amyloidosis represents only a small percentage of causative gross hematuria, it is concerning because of its superfcial resemblance to malignant processes. We report the case of an 82-year-old male with concurrent primary amyloidosis of the kidney, ureter and bladder in the setting of acute hemorrhage. Histopathological examination of several biopsied samples confrmed our diagnosis. A nephroureterectomy with bladder cuff was successfully performed without complication along with watchful waiting for More >

Abstract Since its first report in the 1870s, control of bleeding after transurethral resection of the prostate (TURP) has remained a concern. Foley’s initial report of a urinary catheter involved placement of the balloon into the prostatic fossa following TURP. Removal of prostate tissue with a high-velocity saline stream (Aquablation) is a recently reported alternative to TURP. As Aquablation is heat-free, alternatives to non-thermal hemostasis were sought to optimize the procedure. We report use of a balloon catheter in the prostatic fossa after Aquablation as a post-resection hemostatic method. More >

Abstract Introduction: To characterize our contemporary clinical experience with cryptorchidism.
Materials and methods: The records of boys referred for cryptorchidism were reviewed from 2001 to 2011. Data regarding the incidence of retractile testes, testicular ascent, surgical approach and outcomes were tabulated. Follow up was both early (< 12 weeks) and late (> 12 weeks).
Results: A total of 1885 patients, or 2593 testes, were identified. Eight hundred and forty-one children (45%) or 1204 testes (46%) were retractile on initial exam--57% bilateral; 187 testes (7%) later "ascended" on re-examination and underwent surgery--15% bilateral; 1340 (85%) testes were palpable in the… More >
