What is the optimal frequency in shock wave lithotripsy for pediatric renal stones? A prospective randomized study.

The aim of the study is to compare the effects of varying frequency rates (60, 90, and 120 SWs/min) on the stone free rate and complication rates of pediatric SWL. 75 children with renal stones were divided into 3 groups depending on the SW frequency applied. Group 1.

Renal access in PNL under sonographic guidance: Do we really need to insert an open end ureteral catheter in dilated renal systems? A prospective randomized study.

Purpose: To evaluate the true necessity of open end ureteral catheter insertion in patients with moderate to severe pelvicalyceal system dilation treated with percutaneous nephrolithotomy (PNL) under sonographic guidance.

Patients And Methods: 50 cases treated with PNL under sonographic guidance in prone position for solitary obstructing renal stones were evaluated. Patients were randomly divided into two groups; Group 1: Patients in whom a open end ureteral catheter was inserted prior to the procedure; Group 2: Patients receiving no catheter before PNL.

Functional and morphological recovery of solitary kidneys after drainage. Double J stent placement vs emergency ureteroscopy: which one is reasonable?

The purpose of the study was to evaluate the functional and morphological recovery of solitary kidneys following the relief of obstruction by two different approaches. Data of 65 adult patients with acute renal failure in obstructed solitary kidney were evaluated. Depending on the type of emergent decompression procedure while 34 patients were treated with a double J stent placement only 31 patients underwent ureteroscopic lithotripsy with double J stent placement.

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.

Emergency management of ureteral stones: Evaluation of two different approaches with an emphasis on patients' life quality.

Objectives: To evaluate the emergency management of obstructing ureteral calculi with two different techniques (SWL and URS) with an emphasis on patients life quality.

Methods: A total of 80 patients presenting with acute colic pain due to a single obstructing ureteral stone were treated within 24 hours following the onset of pain with two different approaches in a randomized manner. Patients requiring DJ stent placement and/or auxiliary measures after both procedures were excluded and the remaining 65 patients were evaluated [Group1: ESWL (n = 34); Group 2: URS (n = 31)].

Impaction of ureteral stones into the ureteral wall: Is it possible to predict?

To determine the possible predictive value of certain acute phase reactants CRP and ESR as well as radiologic parameters on the degree of impaction in ureteral 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.

Evaluation of sexual function in patients submitted to ureteroscopic procedures.

Objective: We aimed to evaluate the possible effects of ureteroscopic procedures on the sexual function of both genders.

Materials And Methods: A total of 102 sexually active cases (60 male, 42 female) undergoing ureteroscopic procedures were included in this study. Sexual function has been evaluated in detail by using International Index of Erectile Function (IIEF) in male and Female Sexual Function Index (FSFI) forms in female cases both before and 1-month after the procedures.

A rare cause of renal colic pain: Chilaiditi syndrome.

Chilaiditi syndrome, first described in 1910 by the radiologist Chilaiditi from Vienna, is the interposition of right colon between liver and right hemi diaphragm. It occurs most often in males and its incidence increases with age. It is often detected incidentally during radiological examination.

Does extracorporeal shock wave lithotripsy cause hearing impairment?

Objective: To evaluate the possible effects of extracorporeal shock wave lithotripsy (ESWL) on the hearing status of the patients in this prospective controlled study.

Methods: A total of 40 patients with normal hearing function were included to the study. We had 20 patients each in the study group and control group.
