International Alliance of Urolithiasis (IAU) Guideline on percutaneous nephrolithotomy.

The International Alliance of Urolithiasis (IAU) would like to release the latest guideline on percutaneous nephrolithotomy (PCNL) and to provide a clinical framework for surgeons performing PCNLs.

Material And Methods: Sixty-five adult patients with primary ureteropelvic junction obstruction (UPJO) underwent pyeloplasty between January 2014 and September 2020. Thirty-four patients had laparoscopıc pyeloplasty (LP), 31 patients had open pyeloplasty (OP).

Radiation exposure of patients during endourological procedures: IAEA-SEGUR study.

Fluoroscopy is increasingly used to guide minimally invasive endourological procedures and optimised protocols are needed to minimise radiation exposure while achieving best treatment results. This multi-center study of radiation exposure of patients was conducted by the South-Eastern European Group for Urolithiasis Research (SEGUR), in cooperation with the International Atomic Energy Agency. Seven clinical centers from the SEGUR group collected data for 325 procedures performed within a three-months period, including standard percutaneous nephrolithotomy (PCNL), mini PCNL, retrograde intrarenal surgery (RIRS), semirigid ureterorenoscopy (URS) and flexible URS.

Nation-wide analysis of the impact of Covid-19 pandemic on daily urology practice in Turkey.

Objective: To present a nation-wide analysis of the workload of urology departments in Turkey week-by-week during Covid-19 pandemic.

Methodology: The centres participating in the study were divided into three groups as tertiary referral centres, state hospitals and private practice hospitals. The number of outpatients, inpatients, daily interventions and urological surgeries were recorded prospectively between 9-March-2020 and 31-May-2020.

Radiation Exposure of Surgical Team During Endourological Procedures: International Atomic Energy Agency-South-Eastern European Group for Urolithiasis Research Study.

Fluoroscopy-guided endourology procedures require proper radiation protection to minimize radiation risk. This multicenter study aimed at investigating radiation protection practice and related radiation exposure of operating team members. Six endourology centers from the South-Eastern European Group for Urolithiasis Research answered questionnaires and collected data of 315 procedures performed within a 3-months period, with simultaneous measurement of dose to staff and dose area product (DAP) to patient.

Could ureteral wall thickness have an impact on the operative and post-operative parameters in ureteroscopic management of proximal ureteral stones?

Aim: To evaluate the possible impact of stone impaction in terms of ureteral wall thickness (UWT) on the success and procedure related parameters of ureteroscopic management in proximal ureteral calculi.

Patients And Methods: 82 patients with proximal ureteric stones were included and were divided into 2subgroups where UWT was> 5mm in 38 cases; and <5mm in 44 cases. Stone size, degree of hydronehrosis, diameter of proximal ureteral luz, UWT and patient's demographics were evaluated.

The role of anticholinergic therapy based on the upoint system in the treatment of chronic prostatitis.

Objective: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common problem and severely impairs the quality of life (QoL). We aimed to investigate the effects of different treatment options on voiding symptoms and QoL in patients with urinary phenotype according to the UPOINT system. Matherial and methods: Ninety-six patients with NIH category II,III CP/CPPS were included in the study prospectively.

Reliability and validity of the Bladder and Bowel Dysfunction Questionnaireamong Turkish children.

Background/aim: We developed a Turkish version of the Bladder and Bowel Dysfunction Questionnaire (BBDQ) and evaluated its psychometric properties among Turkish pediatric patients.Materials and methods: The BBDQ was translated into Turkish and then it was back-translated into English. A total of 193 patients were asked to complete the Turkish version of the BBDQ as well as the Dysfunctional Voiding and Incontinence Scoring System (DVISS).

Factors affecting the course of body and kidney growth in infants with urolithiasis: A critical long-term evaluation.

Objective: To investigate the possible effects of dietary, patient and stone related factors on the clinical course of the stone disease as well as the body and renal growth status of the infants.

Patients And Methods: A total of 50 children with an history of stone disease during infancy period were studied. Patient (anatomical abnormalities, urinary tract infection - UTI, associated morbidities), stone (obstruction, UTI and required interventions) and lastly dietary (duration of sole breast feeding, formula feeding) related factors which may affect the clinical course of the disease were all evaluated for their effects on the body and renal growth during long-term follow-up.

Critical evaluation of the overactive bladder and urgency urinary incontinence association with obstructive sleep apnea syndrome in a relatively young adult male population.

Aims: To evaluate the prevalence of Overactive Bladder (OAB) and Urgency Urinary Incontinence (UUI) in males with Obstructive Sleep Apnea Syndrome (OSAS) using the OSAS grading system.

Medical Expulsive Therapy Following Shock Wave Lithotripsy in Ureteral Calculi: An Effective Approach for the Improvement of Health-Related Quality of Life.

Objective: To evaluate the possible effects of medical expulsive therapy (MET) on the health-related quality of life (HRQOL) of patients undergoing shock wave lithotripsy (SWL) for ureteric stones.

A total of 80 adult patients with a single opaque proximal ureteral stone were evaluated. A non-contrast CT was performed in all cases and all possible radiologic predictive parameters calculated.
