Infertility is a common clinical condition and about half of the major causes are due to male-related infertility. Pathogenesis of this abnormality is generally undefined; so establishing a proper treatment option is relatively uncertain. In recent years, several evidences demonstrated that mesenchymal stem cells (MSCs) can be a hope for innovative and efficient treatment of male infertility.

Patients And Methods: This is a case-control study with a case-to-control ratio of 1:3. Out of 5077 patients who underwent PCNL from April 2015 to April 2018 in three different teaching hospitals, 113 had post-PCNL haemorrhages because of AVF and/or PA.
Introduction: This study aimed to evaluate the effect of coronavirus disease (COVID-19) on the patients' referral in the pregnant population and also investigate each treatment approach's advantages and disadvantages for acute renal colic in pregnancy.
Methods: In this retrospective study, we included all pregnant women with ureteral stones referred to a referral center between January 2019 and March 2021.
Results: Among 53 pregnant women, 18 (33.
Renal calculi are becoming more common among children. Although, extracorporeal shock wave lithotripsy (ESWL) is the first choice in this age group, minimal invasive surgeries, such as percutaneous nephrolithotomy (PCNL), are indicated for some patients. Recently, PCNL devices have become smaller in size with acceptable efficacy and lower complications.

We compared the performance of this system with Guy's stone score (GSS) and the Clinical Research Office of Endourological Society (CROES) nomogram. Data from 146 adult patients (87 males, 59%) who underwent PCNL at our institute were used.

The aim of this study was to evaluate the association between dietary intake and stone formation in patients with urinary stones in Shiraz. In this cross sectional study, 110 patients with kidney stone were selected from Faghihi hospital, Shiraz.

Methods: Patients with a single 5-15 mm fragment 3 months after PCNL were enrolled (study group n = 59). The control group (n = 67) consisted of all adult patients with a single 5-15 mm renal stone.
Purpose: To construct, train, and apply an artificial neural network (ANN) system for prediction of different outcome variables of percutaneous nephrolithotomy (PCNL). We calculated predictive accuracy, sensitivity, and precision for each outcome variable.
Methods: During the study period, all adult patients who underwent PCNL at our institute were enrolled in the study.
Introduction: Nephrolithiasis is a common multifactorial kidney disease with worldwide distribution. Compelling evidence, regarding the function of kidney in maintaining the body homeostasis, suggests the role of oxidative stress in the pathogenesis of nephrolithiasis. Glutathione peroxidase 1 is a major antioxidant enzyme, preventing oxidative damage to renal cells by detoxifying hydrogen and lipid peroxides, which may involve in its pathogenesis.

We analyzed the peri-operative parameters, overall treatment costs and changes in the function of the affected kidney on technetium-99 dimercaptosuccinic acid renal scintigraphy, done before the operation and before the final follow-up visit, in 45 adults who underwent PCNL (n = 16) versus laparoscopic (n = 15) versus open (n = 14) AN for large staghorn renal stones. All three groups had statistically similar preoperative characteristics, including the function of the operated kidney on renal scan.

The mineralogy of the stones is investigated using X-ray diffractometry. The samples are classified into five mineral groups (calcium oxalate, uric acid, cystine, calcium phosphate and mixed stone).

Patients And Methods: Between October 2006 and December 2012, the charts of patients who had undergone PCNL and were complicated with massive post procedural bleeding unresponsive to conservative management were reviewed. Those cases in whom angioembolization had failed, or was unavailable, or could not be afforded by the patient were selected and studied.
Purpose: It is believed that extracorporeal shock wave lithotripsy (ESWL) may be less effective than other modalities for treating stones in complex calculi. In this study, we investigated the efficacy of ESWL for treatment of complex stones.
Materials And Methods: Between September 2002 and October 2003, 250 complex cases of urolithiasis, including ureteral stones, staghorn stones, and stones in children, high risk patients, single kidneys, steinstrasse, and horseshoe kidneys were selected to be treated with Siemens Lithostar (Siemens AG, Munich, Germany) on an outpatient basis.
