COVID-19 pandemic impact on clinical outcomes of patients with obstructive pyelonephritis.

Purpose: Obstructive pyelonephritis is a common urologic emergency that requires prompt decompression of the collecting system. The COVID-19 pandemic has changed patient flow and healthcare strategies at numerous emergency departments across Brazil with still unknown consequences for the population. This study sought to investigate the impact of the COVID-19 outbreak on clinical outcomes in patients with acute obstructive pyelonephritis at a tertiary academic center.

Current scenario of endourological treatment of kidney stones in brazil: results of a national survey.

Objective: To elucidate the current scenario of endourology in Brazil for the treatment of urinary lithiasis, with an emphasis on regional differences and the reasons why certain techniques are still underutilized.

Materials And Methods: An electronic questionnaire was sent by email to the 4,745 members of the Brazilian Urological Society (BSU) in 2016 to collect information on the 3 main endourological procedures used in the treatment of nephrolithiasis: Semi-rigid ureteroscopy (URS), Flexible ureteroscopy (F-URS) and percutaneous nephrolithotripsy (PCNL).

Results: A total of 1,267 urologists answered the questionnaire.

Ureterocalicostomy with lower pole nephrectomy in a renal transplant: A case report.

As the number of kidney transplants continues to rise, so does the number and complexities of surgical-related complications, which may be associated with increased morbidity and potentially graft loss. Ureteral stenosis, the most prevalent urological complication, may require diverse techniques for surgical correction depending on several recipient and graft abnormalities. Here we report the surgical and clinical outcomes of a 62-year-old man with a posttransplant pyeloureterostomy stricture successfully treated with ureterocalicostomy after a lower pole nephrectomy.

Is a safety guidewire needed for retrograde ureteroscopy?

Introduction: It is generally advised to have a safety guidewire (SGW) present during ureteroscopy (URS) to manage possible complications. However, it increases the strenght needed to insert and retract the endoscope during the procedure, and, currently, there is a lack of solid data supporting the need for SGW in all procedures. We reviewed the literature about SGW utilization during URS.

Slings may not fail as frequently as believed for stress urinary incontinence: the misinterpretation of postoperative voiding dysfunction as failure based on patient report.

Objective: : Sling operations may obstruct the urethra, promoting voiding dysfunction and secondary urine leakage that are incorrectly attributed to surgical failure.

Methods: : We prospectively evaluated the evolution of urinary symptoms in the postoperative follow-up of 108 polypropylene sling cases. Patients presented for follow-up at 1, 3, 6, 12, 18, 24, 36, and 48 months for review of individual urinary symptoms.

Adjuvant Effect of IV Clodronate on the Delay of Bone Metastasis in High-Risk Prostate Cancer Patients: A Prospective Study.

Purpose: High-risk prostate cancer patients undergoing treatment often experience biochemical recurrence. The use of bisphosphonates as an adjuvant treatment delays skeletal events, yet whether or not bisphosphonates also delay metastastic development remains to be determined.

Materials And Methods: A total of 140 high-risk prostate cancer patients who were undergoing definitive treatment and who had clinically organ-confined disease and who suffered from biochemical recurrence were administered intravenous (IV) clodronate.

Outline of 3,830 male patients referred to urodynamic evaluation for lower urinary tract symptoms: how common is infravesical outlet obstruction?

Introduction: The prevalence of bladder outlet obstruction in men has been overestimated leading to improper clinical results after transurethral resection of the prostate.

Patients And Methods: 3,830 consecutive male cases submitted for urodynamic evaluation were prospectively analyzed using a Schaefer nomogram. The prevalence of detrusor overactivity and the occurrence of obstruction were prospectively studied using standardized urodynamic practice.

Comparative study of the protective effect of different intravenous bisphosphonates on the decrease in bone mineral density in patients submitted to radical prostatectomy undergoing androgen deprivation therapy. A prospective open-label controlled study.

Objectives: To establish whether androgen deprivation therapy (ADT) promotes osteoporosis and osteopenia

Methods: Ninety-four prostatectomized men with rising prostrate-specific antigen (PSA) were enrolled into the placebo group (31), monthly i.v. clodronate (39) or monthly i.

Complications in radical cystectomy performed at a teaching hospital.

Objectives: Radical cystectomy with urinary diversion has been the standard treatment to infiltrative bladder neoplasms. We have analyzed a series of radical cystectomies performed by residents at a school hospital and compared the rates of complications in this series with those reported in literature.

Materials And Methods: During the period of December 1996 to December 2000, 59 surgeries were performed by 8 residents in our department, always oversaw by the same assistant.

International Prostate Symptom Score--IPSS-AUA as discriminat scale in 400 male patients with lower urinary tract symptoms (LUTS).

Objective: This study analyzed the total symptom score, irritative and obstructive domains of IPSS questions regarding quality of life and the urodynamic diagnosis in 400 men with LUTS.

Materials And Methods: Four hundred consecutive male patients were prospectively enrolled after being submitted to full urodynamic evaluation and IPSS. Obstructed and non-obstructed patients were compared regarding the symptoms score and quality of life.

A randomized and prospective study on the value of antibiotic prophylaxis administration in transurethral resection of the prostate.

Context: Antibiotic prophylaxis in transurethral resection of the prostate is a regular practice in urology. However, its prophylactic effect can be questioned when the antiseptic surgical technique is used. Nonetheless, urine culture-oriented antibiotic therapy is the gold standard for avoiding improper medication usage and bacterial resistance.
