RESUMO

BACKGROUND: Varicocele is one of the most common treatable causes of male infertility, and its treatment may be beneficial for fertility. This study aimed to evaluate fertility rate and DNA fragmentation index (DFI) following varicocelectomy in primary infertile men with clinical varicocele. MATERIALS AND METHODS: This prospective longitudinal study was conducted on primary infertility men, in a tertiary center from December 2018 to December 2019 with one-year follow-up. Data of the semen parameters, DFI (%), and fertility rate were gathered before, as well as 4 and 12 months after undergoing varicocelectomy. For data analysis, SPSS software and analytical test were used. RESULTS: Out of 76 patients who were analyzed, 22 (29%) became fertile and 54 (71%) remained infertile. Semen parameters and DFI (%) were improved significantly following varicocelectomy (P<0.001). Smoking history, occupational heated exposure, body mass index (BMI), and infertility duration were determined as predictors associated with fertility status (P<0.05). CONCLUSION: Although varicocele repair improved the DFI, the fertility rate was achieved in less than one-third of patients; it seems that the other parameters, such as the history of smoking, occupational heated exposure, overweight, and duration of infertility should be considered as predictors of fertility status, in primary infertile men who are a candidate for varicocelectomy.

RESUMO

OBJECTIVE: The neurogenic bladder is one of the most serious and painful disorders seen in pediatric urology clinics. The upper urinary tract can be impaired by increased bladder pressure. Botulinum toxin-A (BTX-A) is one of the new therapeutic interventions for this disease. Thus, this research was designed to determine the clinical as well as radiological outcomes intravesical BTX-A injections in patients with overactive neurogenic bladder with Detrusor over activity. PATIENTS AND METHODS: From March 2012 to March 2019, this cohort study was conducted at Shahid Labbafinejad hospital in Tehran, Iran. Thirty-five pediatric patients with a neurogenic bladder and Detrusor overactivity who fulfilled the eligibility criteria received BTX-A injections. Demographic data, including spinal cord lesions or congenital malformations, upper and lower urinary tract nuclear scans, evidence of vesicoureteral reflux (VUR) and its severity, and hydronephrosis and 72 h voiding diary before and after intervention were all recorded. RESULTS: The mean ± standard deviation age of participants was 9.47 ± 4.61 years. After injection, nocturia and urination frequency as general symptoms of the overactive neurogenic bladder improved (p < 0.05). Also, the severity of hydronephrosis was decreased in 33% of patients following injection. In our study, 32 out of 35 patients had vesicoureteral reflux. Of those, there was complete resolution and downgrading of VUR in 17 (53.12%) and 13 (40.62%) respectively. CONCLUSION: In the evaluation of voiding cystourethrography (VCUG) before and after the injection, downgrading of VUR was seen in 53% of the cases. In the 99mTc-DMSA nuclear scan before and after the injection, the appearance of a new parenchymal scar and uptake reduction was not observed, which indicates the cessation of scar formation in all patients. Although Enuresis, Urgency, Frequency, Nocturia, and UUI significantly improved after injection.

RESUMO

BACKGROUND: Retrorenal colon is a risk factor for colonic injury during percutaneous nephrolithotomy (PCNL). Our aim in this study is to report the feasibility and outcomes of ultrasound-guided percutaneous nephrolithotomy in patients with preoperatively known retrorenal colon by cross-sectional imaging. METHODS: In this prospective study, all patients with large renal stones and retrorenal colon in preoperative cross-sectional imaging from September 2020 to January 2022 who were candidates for PCNL were enrolled. Percutaneous access was established by ultrasonography guidance by the freehand method with dilation of the tract by a combination of fluoroscopy and ultrasonography. RESULTS: Of the 1123 patients (Male = 760 and Female = 363) who underwent PCNL, 13 patients (Male = 6 and Female = 7) had retrorenal colon in the preoperative computed tomography. The series included two patients with malrotated kidneys. Complete stone clearance was achieved in 11 patients. Patients were followed up for at least 3 months. No serious postoperative complications were observed during follow-up. CONCLUSION: In selected patients and experienced hands, ultrasound-guided PCNL can be an alternative option for the treatment of patients with large renal stones who have retrorenal colon in cross-sectional imaging.

RESUMO

Adjustment of immunosuppressive and COVID-19 treatment in terms of drug interactions is still challenging. Herein, we report a 45-year-old woman with end-stage renal disease due to autosomal dominant polycystic diseases (ADPKD) with COVID-19 and pulmonary involvement following kidney transplantation. The patient was properly treated by discontinuation of immunosuppressive drugs, bronchoscopy, and high volume of blood transfusions. The fact that we quickly used early intubation and a new treatment regimen that suppressed immune systems may help physicians develop optimal treatment strategies for similar severe cases. However, this treatment method requires more detailed evaluations due to the contradictory results in reviewing other studies.

RESUMO

Isolated renal hydatid disease is a rare endemic infestation caused by larval form of Echinococcus granulosus. Hydatiduria is an uncommon presentation of renal hydatid disease. In 2012 a 34-year-old female referred to Razi Hospital, Rasht, Iran with complaints of right flank pain and grape-like material in urine. Diagnosis was made by ultrasonography and CT scan. The patient was treated surgically with nephrectomy in combination with perioperative chemotherapy with albendazol.
