Serum levels of testosterone (ST) and high-density lipoprotein (HDL) are generally associated with atherosclerosis in male patients over 50 years with critic iliac stenosis (TASC II A and B) and cardiovascular disease with significant changes in HDL and low-density lipoprotein (LDL). In addition to the standard therapy, combined medicamentous therapy and adequate model of exercise are also important factors as medicines can improve HDL levels and primary bypass and endovascular potency impacting positively on improvement of ST or it can be the following testosterone replacement therapy (TRT) comprising cardiovascular disease prevention and vascular treatment as adjunct therapy options after endovascular and vascular surgical procedures. The aim of the study is to identify the association between HDL and ST after surgical and endovascular intervention on the iliac segment (TASCII A and B), as well as cardiovascular risk factors with modified medium activity (MET) <6 with short interval increase over >6 (MET), with total duration of 30–60 minutes. It also attempts to remodel a patient behavioral pattern, optimize ST levels and link them to outcomes and patency of vascular procedures on the iliac segment. Materials and methods. 108 selected male patients with cardiovascular disease combined with metabolic syndrome and critical iliac artery stenosis (TASC II A and B) were examined during 2014–2018, 4 years after invasive and minimal invasive treatment (54 patients were treated with surgical Dacron reconstruction and 54 patients – with endovascular treatment on short segment of critical iliac artery stenosis (TASC II A and B). Results. In the total population, no difference was observed in changes of constraint-induced movement therapy between the standard exercise group and the control one after 4 years from baseline. However, there was no significant interaction between the effect of exercise trainings and primary bypass potency within 4 years. Conclusions. Primary effects of endovascular procedure and Dacron bypass revascularization raise the risk of elevated testosterone levels after 4 years of group training but does not provide adequate answers to questions as to whether higher levels of ST have any major influence on primary bypass potency preventing further progression of cardiovascular disease and general symptomatic and asymptomatic atherosclerosis. However, exercise and TRT can be potential adjunctive therapeutic options for a future supporting postsurgical and endovascular illiac treatment in cardiovascular patients with low testosterone levels.

Introduction The optimal management of distal ureteral stones remains a matter of debate since current guidelines favor ureteroscopy over extracorporeal shock wave lithotripsy (ESWL). We aimed to evaluate the efficiency of ESWL for distal ureteral stones and to identify factors that affect treatment outcomes. Materials and methods The retrospective study included records of 115 patients with distal ureteral stones, 5 mm to 18 mm in size, undergoing 223 ESWL sessions as an outpatient procedure. Early fragmentation and three-month follow-up stone-free rate (SFR) was assessed through radiographic imaging. Treatment was successful if there were no residual fragments or they were ≤4 mm, three months after the last session. Results The mean ±standard deviation (range) stone size was 9.68 ±3.10 (5.00-18.0) mm. The mean body mass index (BMI) was 24.3 ±2.67 (18.4-29.8) kg/m² with a significant correlation between BMI and stone size (r2 =0.324, p <0.001). Patients underwent ESWL an average of 1.7 ±1.36 times (1-5), while 68 patients (59.1%) became stone-free after one session. The overall SFR was 82.6%; for patients with stone sizes ≤10 mm and >10 mm, it was 99% and 9.4%, respectively. Cumulative SFR after the second session was 77%. In 20 (17%) patients the treatment was a failure. Complications occurred in 10.4%, while auxiliary procedures were needed in 8.7% of cases, both significantly affected by the stone size (p <0.001). The efficiency quotient (EQ) was 0.76. Treatment outcome was significantly different depending on stone size, BMI, number of sessions, complications, and auxiliary procedures (p <0.001, p =0.022, p <0.001, p <0.001, p <0.001, respectively). Univariate regression analysis identified stone size and BMI as significant predictors of treatment outcome (odds ratio (OR) 3.84, 95% confidence interval (CI): 2.31-8.97, p =0.001, and OR 1.25, 95% CI: 1.04-1.54, p =0.024, respectively). Conclusions Extracorporeal shock wave lithotripsy continues to be a safe and effective option for managing simple calculi in distal ureters with a diameter of ≤10 mm. The stone size and BMI remain significant predictors of treatment outcome.

What is the outcome of intracytoplasmic sperm injection (ICSI) using testicular spermatozoa obtained on the day of oocyte pick-up (OPU) or the day before OPU. Testicular spermatozoa were obtaining the one day before OPU does not affect fertilization rate, top quality embryo on day 3, and blastocyst utilization rate. Usually, TESE is performed just before OPU. OPU is generally cancelled if no sperm is retrieved. The use of fresh testicular spermatozoa, obtained the day before OPU could offer the couple and the caring team both medical and practical advantages. The benefits of this approach, however, has not been evaluated in detail. An uncontrolled preliminary study has revealed that regular fertilization and pregnancy rates could be achieved with sperm extraction performed one day before OPU. This was a single-center retrospective study in Bahceci BIH IVF center. Sixty-six patients suffering from azoospermia from January 2015 to December 2020 were evaluated. TESE was performed either on the OPU day (43 patients; group A) or one day before OPU (23 patients; group B). In this study, primary outcomes were motile spermatozoa at ICSI, fertilization, top quality embryo on day 3, and blastocyst utilization rate. Statistical analyses were performed with chi-squared tests. There is no statistical difference fertilization rate (72.3% vs. 72.2, p > 0.05), top quality embryo rate on day 3 (58.3% vs 58.3%, p > 0.05) and blast utilization rate (43.98% vs 49.58%, p > 0.05) between group A and B, respectively. The retrospective nature of this study may not eliminate potential bias. On the contrary, the strength of our study is that all procedures were performed by the same operators, so there are no operator-dependent differences. More research is needed to prove our findings. Wider implications of the findings: TESE procedure can be performed one day before OPU without compromising success. 1

Crossed fused renal ectopia (CFRE) is a rare congenital abnormality of the urinary tract where the kidneys are fused on one side, while the ureter of the ectopic kidney crosses the midline with the normal entrance in the bladder on the contralateral side. Congenital anomalies are associated with a stone formation whose management represents a real challenge. To our knowledge, we report the second case of CFRE associated with ureteral stone, which has been successfully resolved with Extracorporeal Shockwave Lithotripsy (ESWL) and the first of its kind where a sufficient degree of stone disintegration has been achieved after a single session with a complete stone clearance during the follow-up. Radiological examination showed an inferior type of CFRE with stone in the proximal part of the ureter of the upper kidney. ESWL is an acceptable and effective treatment option in CFRE patients due to the minimally invasive approach, potentially high stone-free rate, and rare complications.

Introduction: Microdissection testicular sperm extraction (microTESE) is considered the gold standard method for surgical sperm retrieval among patients with non-obstructive azoospermia (NOA). Aim: This study aimed to evaluate the correlation between histopathological findings after failed microTESE procedure and outcomes of the „second-look“ procedure and to provide insight into the most common histopathological patterns after testicular biopsy within our population. Methods: The retrospective study included 33 selected patients with NOA, who had undergone unsuccessful sperm retrieval. The diagnosis of NOA was made after the assessment of the patient’s history data, a physical examination, semen analysis, the hormonal profile, and genetic studies. After negative sperm retrieval, histopathological report has been analyzed for „second-look“ microTESE attempt. Results: Five testicular histopathological patterns were found: hypospermatogenesis (9,1%), Sertoli cell-only syndrome (43%), germ cell maturation arrest (15%), seminiferous tubule hyalinization (15%), mixed pattern (21%). Y-microdeletions were detected in 5 patients, of which 3 patients showed AZFc region deletions. Only 3 patients (9,1%) underwent a „second-look“ procedure after the evaluation of histopathological reports. After the stimulation therapy and „second-look“ procedure, we had a positive outcome in a single patient (33,3%). Mean FSH value in patients with confirmed spermatogenesis was 17.26±3.11IU/l, while mean FSH value in patients without presence or germ cell statistically significantly exceeded and was 24.28±4.71IU/L (p=0.038). Conclusion: Histopathological reports following the microTESE procedure are obligatory for the proper selection of patients who are candidates for the „second-look“ microTESE attempt. Patients with Sertoli cell-only syndrome and hypospermatogenesis particularly can benefit from the “second-look” procedure.

Introduction: Ventilator associated pneumonia (VAP) is defined as nosocomial pneumonia in patients who have mechanical ventilation (MV) for more than 48 hours. The diagnosis of VAP is based on radiological-microbiological examinations. In the United States, the Centers for Disease Control and Prevention (CDC) and the National Health Care Network (NHSN) have an incidence of VAP of 5.8% per 1,000 days on mechanical ventilator. Aim: In this study, we had an aim to determine the occurrence of ventilator-associated pneumonia (VAP) in patients with MV who were hospitalized in the intensive care unit. Method: The study was retrospective, clinical, conducted in the period from January 1, 2016 until December 31, 2016. In a one-year period, 719 patients of both sex, aged 14 to 91, were hospitalized in the intensive care unit of the Clinic for Anesthesia and Resuscitation of the University Clinical Center in Sarajevo. The study included 250 patients of both sex who had respiratory support with mechanical ventilator. No patient was excluded from the study. As a confirmation of VAP, we used microbiological reports from the patient history documentation. The results were presented statistically through tables and graphs, numerically, by a percentage, and by a mean value with standard deviation. Results: Out of the 719 hospitalized patients, 250 or 34.8% underwent controlled ventilation. In 103 or 41.2% of patients some form of pneumonia was confirmed microbiologically. An average patient age on controlled ventilation was 60.4 ± 16.8 years. The mean age of a female patients who were on controlled ventilation was 63.2 ± 16.7, higher than that of male patients, which was 57.8 ± 16.6 years. The most frequent patients were over 60 years of age (52.8%). The shortest hospitalization of patients on controlled mechanical ventilation was 1 day and the longest was 120 days. Average duration of mechanical ventilation was 6.9 ± 10.5 days. Conclusion: VAP is a relatively common complication in patients with MV that can increase morbidity and mortality, as well as treatment costs. It is more frequent in females and in the elderly. Medical staff should provide normal maintenance of respiratory functions to a patient who is on MV, which will reduce the risk of VAP.

Abstract Introduction. Bladder cancer is the most common malignancy involving the urinary system. Recent research tends to emphasize the role of oxidative stress products in the carcinogenesis of bladder cancer. The level of oxidative stress can be measured by assessing the MDA levels. This study aimed to evaluate serum MDA levels in patients with bladder cancer, as well as to determine its potential role as a biomarker in the diagnosis of the disease and progression risk considerations. Methods. The study was designed as a cross-sectional study and included 90 patients, divided into three groups with 30 patients each: Ta, T1and T2–T4 group, based on histopathological findings after transurethral resection of the tumor. The control group included 30 healthy volunteers. MDA level was determined using the spectrophotometric method. Results. Serum MDA level in patients with bladder cancer [0.86 (0.78–1.05) μmol/L] was significantly higher than the serum MDA level in control group [0.70 (0.69–0.72) μmol/L] (p < 0.001). Serum MDA level in Ta group [0.73 (0.70–1.05) μmol/L], T1 group [0.85 (0.80–1.12) μmol/L] and in T2–T4 group [0.91 (0.84–1.04) μmol/L] was significantly higher than the serum MDA level in control group [0.70 (0.69–0.72) μmol/L] (p < 0.01). MDA level in T1 and T2–T4 group was significantly higher than the MDA level in Ta group (p < 0.01). No significant difference was observed in MDA level between T1 and T2–T4 group (p = NS). A statistically significant positive correlation was found between tumor size and serum MDA level in patients with bladder cancer (rho = 0.254 p < 0.01). Conclusions. The results of the present study suggest that MDA serum level might play a significant role as a biomarker in the diagnosis of bladder cancer, as well as in the monitoring of its progression.
