Introduction: Some infants with obstructed megaureters or ectopic ureters requiring surgery undergo a cutaneous ureterostomy followed by definitive repair after 12 months of age. Since 2013, a 'mini' extravesical reimplant with or without 'mini' tapering (MER) was performed instead of cutaneous ureterostomy in such infants.

Objective: To describe the technique and outcomes for MER. Read More

Introduction: Ureteropelvic junction obstruction (UPJO) is a condition characterized by partial or complete obstruction of urine transport from the renal pelvis to the ureter and can present with intermittent flank pain, recurrent urinary tract infections, renal stones, or renal dysfunction. While historically, open pyeloplasty was the gold standard for surgical management, laparoscopic methods to repair UPJO have largely taken over as the preferred approach for adolescent and adult patients. Despite near universal adoption of laparoscopic pyeloplasty among Canadian urologists, it remains a technically complex procedure and considerable variability exists in the procedural steps performed.

Background: Zinner syndrome represents a rare congenital malformation of the urinary tract. It comprises a constellation of Wolffian duct anomalies and is almost exclusively encountered as a classic triad of seminal vesicle cysts, ejaculatory duct obstruction and renal agenesis. Patients can be either asymptomatic or symptomatic. Read More

The review article presents information from foreign and domestic authors on the relevance of studying the incidence of men with bening prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). Complex urodynamic studies (CUDS) remains the most informative test of the degree of expression of LUTS and bladder outlet obstruction () caused by BPH. The difficulty in interpreting the results, the invasiveness and inaccessibility of CUDS in the routine practice of most medical institutions makes it necessary to perform relatively simpler and more accessible methods of research, which do not always objectively reflect the degree of urinary incontinence in older men.

Aim: Radical treatment of prostate cancer (PCa) is often associated with the development of urinary incontinence (UI). The etiology of UI after prostatectomy is multifactorial and can be caused by both urethral sphincter deficiency and bladder dysfunction. To date, there are no comparative studies of the development of UI in patients after either organ-preserving treatment or radical prostatectomy (RP). Read More

Purpose: There are few published reviews that have assessed the clinical utility of renal urine cultures following percutaneous nephrostomy (PCN). In this systematic review, we evaluated the published evidence of the clinical utility of nephrostomy urine cultures in the light of emerging antimicrobial resistance and need for stewardship.

Background: Ureteroscopy combined with laser stone fragmentation and basketing is a common approach for managing renal and ureteral stones. This procedure is associated with some degree of ureteral trauma. Ureteral trauma may lead to swelling, ureteral obstruction, and flank pain and may require subsequent interventions such as hospital admission or secondary ureteral stent placement. Read More

Purpose: To compare the 12-month post-prostatic artery embolization (PAE) clinical outcomes of patients who were and were not taking 5-alpha-reductase inhibitors (5ARIs) at the time of PAE.

Materials And Methods: A retrospective review was conducted of patients who underwent PAE from 2010 to 2017 due to lower urinary tract symptoms, secondary to benign prostatic hyperplasia (BPH). One hundred fifty-five patients were included and divided in 2 groups; these groups did not present statistically significant differences in their baseline characteristics-those taking 5ARIs (Y-5ARIs, n = 40) and those not taking 5ARIs (N-5ARIs, n = 115).

Background: Diagnosis of renal function impairment and deterioration in congenital urinary tract obstruction (UTO) continues to be extremely challenging. Use of renal biomarkers in this setting may favor early renal injury detection, allowing for a reliable choice of optimal therapeutic options and prevention or minimization of definitive renal damage.

Methods: This longitudinal, prospective study analyzed the first-year profile of two serum renal biomarkers: creatinine (sCr) and cystatin C (sCyC); and six urinary renal biomarkers: neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), transforming growth factor beta-1 (TGF-β1), retinol-binding protein (RBP), cystatin C (uCyC), and microalbuminuria (μALB) in a cohort of 37 infants with UTO divided into three subgroups: 14/37 with unilateral hydro(uretero)nephrosis, 13/37 with bilateral hydro(uretero)nephrosis, and 10/37 patients with lower urinary tract obstruction (LUTO), compared with 24 healthy infants matched by gestational age and birth weight.

Introduction: Diuretics improve visualization of the urinary tract in computed tomography urography in adults, as well as in magnetic resonance urography in adults and children. Also, diuretics can help to diagnose upper urinary tract obstruction in intravenous urography, ultrasonography or dynamic scintigraphy.

Introduction: Robert Whitaker, inspired by Dr William W Scott at the Brady Institute at Johns Hopkins and by Sir David Innes Williams at Great Ormond Street Hospital for Children in the late 1960s, spent much of his career exploring the meaning of persistent dilatation of the upper urinary tract, in an attempt to define obstruction and to find a means of diagnosing it accurately.

Objective: This is a historical review of Bob Whitaker's journey from his definition of obstruction to the inception of his eponymous test.

Results: In 1975, he proposed a theory to explain the pathophysiology behind obstructive hydronephrosis and megaureter. Read More

Background: Ureteral stents have been widely used in kidney transplantation to prevent postoperative ureter-related complications such as ureteral stricture, ureteral obstruction, and ureteral leakage; however, a longer indwelling ureteral stent time corresponds to a greater risk of complications such as urinary tract infections. Currently, transplantation centers have not yet reached an agreement on the time to remove ureteral stents. Several randomized controlled trials (RCTs) have evaluated the optimal removal time for ureteral stents. Read More

Introduction: Silodosin determines smooth muscle relaxation in bladder and prostate tissues, increases bladder blood flow in conditions of chronic bladder ischemia and regulates the activity of transcriptional factors responsible for stromal growth and prostate hyperplasia. Phase III trials have already demonstrated the efficacy and safety of silodosin in the treatment of patients bothered by lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH).

Objective: We aimed to describe the rationality for the use of silodosin and to summarize the current literature on the use of Silodosin for the treatment of LUTS. Read More
