Semen's parameters after varicocelectomy surgery with mast cell stabilizers treatment in infertile varicocele patients: Randomized clinical trial study.

Background and Aims: Varicocele is one of the most common causes of male infertility in which testicular function is progressively damaged. This study aims to investigate the effect of varicocelectomy and mast cell stabilizers on reducing sperm DNA fragmentation in infertile patients with varicocele. Methods: In this randomized clinical trial, after obtaining ethical approval and informed consent, infertile patients with varicocele were randomly assigned to three groups: varicocelectomy, 1 mg ketotifen, and varicocelectomy plus with 1 mg ketotifen for 3-month follow-up. Semen analysis and estimation of DNA fragmentation index (DFI) were obtained from all people in the studied time periods. Results: In this study, 420 infertile patients with varicocele were included with an average age of 31.6 years. The results showed that sperm morphology, sperm motility, sperm count, and sperm DFI had significant differences after the intervention (p < 0.05). Also, the results of semen analysis for each group showed that there was a significant improvement in sperm morphology, motility, count, and DFI index of infertile people with varicocele after the intervention (p < 0.05). But the difference was statistically higher in the varicocelectomy plus with 1 mg ketotifen group than in the other groups (p < 0.01). Conclusion: The evidence and results of this study showed that the use of varicocelectomy plus ketotifen in infertile people with varicocele was more effective in improving Semen parameters than the use of mast cell stabilizers or varicocelectomy alone.

Cytotoxic Effect of Saffron Stigma Aqueous Extract on Human Prostate Cancer and Mouse Fibroblast Cell Lines.

PURPOSE: Several lines of experimental evidence have shown that saffron has anticarcinogenic effects. This study aimed at evaluating the possible anticancer effect of saffron stigma aqueous extract on human prostate cancer (PC3) and mouse fibroblast cells (L929) as non-cancerous control cells. MATERIALS AND METHODS: Saffron stigma aqueous extract at concentrations of 100, 200, 400, 600, 800, 1600 and 3200 µg/mL were prepared. PC3 and L929 cells were incubated with different concentrations of saffron extracts in different time intervals (24, 48, 72, 96 and 144 hours). MTT assay was used for each cell line to investigate the cytotoxic effect of saffron. Morphological alterations were also observed under light inverted microscope. RESULTS: In fibroblast cell line after 24 hours, Saffron extract did not affect significantly the normal cells and they were intact in morphologic view. After 96 hours in the cells with highest concentration (1600 µg/mL), cell death and cellular form changes as well as severe granulation was observed. In prostate cell line after 24 hours, the only changes were observed in cells with the concentration of 1600 µg/mL. The cells were granulated and the form of the cells were spherule. After 72 hours, in group with the concentration of 1600 µg/mL, severe granulation was observed and the cell count decreased and some cells were dead. CONCLUSION: Saffron aqueous extract has an in vitro inhibitory effect on the proliferation of human prostate cell and mouse L929 cells which is dose-dependent.

Effect of Unilateral Iatrogenic Testicular Torsion on the Contralateral Testis in Rats: Prepubertal and Postpubertal.

PURPOSE: The present study was conducted to investigate the influence of hemicastration and age at hemicastration on the contralateral testis weight and function/testosterone production. MATERIALS AND METHODS: 64 Wistar-derived male rats were divided randomly into 4 groups. Group 1 was named immature intervention, group 2 immaturecontrol, group 3 mature intervention, and group 4mature control. In group 1, rats were hemicastrated at 30 days of age (prepubertal). In group 2, sham surgery (midscrotal incision) was per-formed atthe same age. In group 3, rats were hemicastrated at 70 days of age (postpubertal) and in group 4,sham surgery was done at the same age. Twenty days after the first surgery, contralateral orchiectomy wasperformed in intervention groups and controls underwent random orchiectomy (left or right). Blood sampling for evaluation of serum testosterone was performed just before second surgery. RESULTS: The mean testis weight (1692 ± 26.7 in group 1 versus 1375 ± 39.7 in group 2; P < .001 and 1760 ± 26.6 in group 3 versus 1425 ± 44.9 in Group 4; P < .001) and the mean testicular weight (mg) per 100 g of body weight (735.8 ± 82.3 in group 1 versus 634.8 ± 84.8 in group 2; P = .005 and 652.4 ± 61.4 in group 3 versus 572.6 ± 97.7 in group 4; P = .03) were significantly greater in hemicastrated rats as to their controls. Also, these parameters was greater in prepubertal group than postpubertalhemicastrated rats. There was no appreciable difference in serum testosterone levels across the 4 groups (P = .77). CONCLUSION: Our research demonstrated that hemicastration results in compensatory hypertrophy of the remaining testis and it decreases as the animals age. Hemicastration does not lead to reduction in serum testosterone levels and the remaining testis can retrieve a normal serum testosterone level.

Evaluation the result of warm normal saline irrigation in ureteral endoscopic surgeries.

PURPOSE: Transurethral lithotripsy (TUL) is a major modality for the endoscopic management of ureteral stones. Ureteral spasm makes access for ureters difficult, which causes impaction of the ureteroscope, ureteral dislodge, and a low success rate of endoscopic surgeries. This study described the outcomes of a new endoscopic surgical experience by use of 40-degree warm saline irrigation during TUL compaired with routine ambient air irrigation in TUL. MATERIALS AND METHODS: In this randomized clinical trial from 2014 to 2015, 150 patients with ureteral stone with balanced randomization were divided into two parallel groups. Patients underwent TUL in the first group with 20-25 degree saline irrigation and in the second group with 40-degree saline irrigation. One surgical team with the same semi-rigid instrument performed all TULs and the other steps were similar in both groups. Complete stone fragmentation was measured as the primary outcome and the duration of procedure, retrograde stone migration and all and any intraoperative complications were the secondary measurements. RESULT: While comparing warm saline irrigation with cold saline irrigation, the rate of access to upper ureter was 95% versus 72%, stone retropulsion frequency was 10.7% versus 30.7% and the stone-free rate was 96% versus 76% respectively (P < .05). There was no ureteroscope impaction and ureteral dislodge in both groups. CONCLUSION: Using warm saline irrigation in endoscopic surgeries results in better surgical outcomes including a lower ureteral spasm rate, greater ureteral muscle relaxation and better access to the upper ureteral zone, and a lower rate of complications, such as ureteroscope impaction, ureteral dislodge and stone retropulsion.

Evaluation of the Effect of Meatal Stenosis on the Urinary Tract by using Ultrasonography.

PURPOSE: Circumcision is one of the oldest surgical procedures that originated for religious purposes. Circumcision in infancy is a common procedure in our country and secondary meatal stenosis due to circumcision is a common complication. The aim of our study is to determine the effect of meatal stenosis on the lower and upperurinary tract of circumcised boys by using ultrasonography. MATERIALS AND METHODS: In this cross-sectional study, we enrolled 87 circumcised boys between 4 to 8 years old with severe meatal stenosis. Clinical findings of our subjects were gathered by a checklist that included: thin stream of urine, upward urine stream deviation, infrequent voiding, urinary tract infections, voiding dysfunction, and urge incontinency. In lab data analysis, complete blood cell count (CBC), urine analysis, urine culture, blood urea nitrogen (BUN), and plasma creatinine level were evaluated. Ultrasonography detected hydronephrosis, hydroureter, bladder wall thickening in a full and empty bladder, bladder volume, and residual urine volume. RESULT: Narrowing of urine stream is commonly seen (about 54%) among patients with severe meatal stenosis, and similarly in sonographic evaluations the most common symptoms among patients was thickening of the bladder wall that increased in an empty and a full bladder (about 82%). CONCLUSION: The author of this study recommends performing long-term follow up after circumcision and ultrasonographyto detect meatal stenosis before permanent renal damage occurs.

Retroperitoneal Fibrosis Due to Opium Abuse: A Case Series and Literature Review.

Retroperitoneal fibrosis (RPF) is a rare condition with an unclear etiology, presenting with the development of aberrant chronic nonspecific fibroinflammatory tissue in the retroperitoneal space, which can result in entrapment and obstruction of the retroperitoneal structures. RPF is a subtype of chronic periaortitis, and can be divided into two types: primary (or idiopathic) and secondary. RPF is usually idiopathic, but can also be secondary to malignancies, certain drugs, infections, surgery, and trauma. The systemic clinical manifestations are nonspecific and include low-grade fever, fatigue, anorexia, weight loss, and myalgia. We report five patients admitted to our hospital with clinical, laboratory, imaging, and pathologic findings compatible with RPF, and we describe their treatment and follow-up. We were suspicious that the impurities of some types of opium have an important role in the pathogenesis of RPF. Some of our patients used opium again after the follow-up period; however, they used a different type with a different origin, and we were surprised to see that RPF did not form again.

Short-Period Influence of Chronic Morphine Exposure on Serum Levels of Sexual Hormones and Spermatogenesis in Rats.

BACKGROUND: Increased rates of addiction and its broad societal complications are well known. One of the most important systems that may malfunction in drug abusers is the reproductive system, and evaluating patients for this potential risk may lead to increased awareness. MATERIALS AND METHODS: Thirty 60-day-old male rats were divided into control and target groups. The target group underwent 5 mg/kg intraperitoneal injections of morphine twice a day while the control group underwent normal saline injections (at the same dosage). After 60 days, the rats were anesthetized, and after blood sampling, they underwent bilateral orchiepididymectomy. Histological and hormonal evaluations were performed on the samples. RESULTS: Levels of sex hormonal features and spermatogenesis were significantly reduced in the target group compared to the control group. LH levels showed a meaningful decrease in the target group, but FSH and testosterone levels did not. On histological section analysis, mature sperm were meaningfully decreased in the target group. CONCLUSIONS: Chronic use of opioids may lead to alterations in sexual features and sexual hormones. Therefore, opioids have the potential to cause infertility. These changes may result from the effect of the drugs on the hypophysis or hypothalamus, the direct effect of the drugs on the seminiferous tubules, or a combination of both. The findings suggest that public awareness about addiction may cause decreased infertility rates.

Angiofibroma of the vulva.

BACKGROUND: Cellular angiofibroma is a benign and rare tumor. It usually arises in middle-aged women and involves the vulva. Complete local excision of the tumor is the best cure, and, usually, there is no recurrence after surgery. CASE REPORT: We describe a 20-year-old woman with a painless, growing vulvar mass who presented about 3 years ago. Her past medical history was negative for oral contraceptives, tobacco, and alcohol, and there were no similar lesions in her family history. A physical examination revealed two masses on the right and the left labia majora and similar lesions on the left axilla and both breasts. An uncomplicated simple resection of the vulvar masses was done in the operating room. There was no evidence of recurrence 12 months after surgery. Histopathologic examination revealed that the findings were consistent with the diagnosis of the cellular angiofibroma. Based on our knowledge, this patient is the youngest case of vulvar angiofibroma. The lesions were large and symmetrical (on both labia majora), although they differed in size. Extravulvar (breast and axilla) lesions were also noteworthy in this patient.
