This study aimed to assess the ten-year trend in semen quality among couples referred to the Infertility Center in Kerman between 2008 and 2017. The study included 2952 semen samples from men 18 to 60 years old referred to the infertility center as infertile couples living in Kerman province, Iran, whether they had normal or abnormal semen analysis. A total of 2952 sperm samples were included. Statistically significant changes were observed in semen parameters. Particularly, significant changes were observed for volume (−0.08 mL/year), sperm concentration (−2.34 (mio/mL)/year), total sperm count (−13.17 (mio/ejaculate)/year), progressive motility (−2.62%/year), non-progressive motility (−0.59%/year), immotile sperm (2.49%/year), and normal morphology (−0.134%/year). In bivariate analysis, the prevalence of oligozoospermia in this study showed a statistically significant association with age (OR = 1.019; 95% CI = 1.007−1.032; p = 0.003). Likewise, there was a statistically significant association with the year (OR = 1.087; 95% CI = 1.050−1.125; p = 0.000). Semen quality parameters showed a downtrend during the last 10 years in this study, emphasizing the importance of male reproductive health monitoring and warning public health coordinators to pay more attention to this important issue.

Objectives: Bladder-Sparing Approach was presented in patients who are not willing or not suitable for Radical Cystectomy (RC). There have been inconsistencies in the literature regarding the comparison of survival rates of these two methods. Our objective is to evaluate the survival rate of patients with muscle-invasive bladder cancer (MIBC) undergoing different treatment methods. Design: Retrospective cross-sectional study. Setting: A secondary care, multicenter study in Kerman, Iran 2008 to 2016. Participants: All 200 patients who were diagnosed with Muscle Invasive Bladder Cancer and were admitted to our hospitals. Patients with inaccessible medical files and patients with pathologies other than TCC were excluded. Main outcome measures: Radical cystectomy and different methods of bladder preservation were compared based on their survival rate. Interventions: Radical cystectomy or bladder preservation Results: Overall survival of the patients was 2 years [95% CI: 1.37–2.63]. The overall 5-year survival rate of patients with MIBC was 32%. Having a 6.4 years overall survival, the RC group showed the highest survival compared with others (p = 0.01); the overall survival of patients undergoing TMT, TURT, chemotherapy, or radiotherapy monotherapy was 3.15 years [95% CI: 2.242–4.061], 4.06 [95% CI: 3.207–4.931], 2.58 [95% CI: 1.767–3.399], and 3.14 [95% CI: 1.614–4.672] years, respectively. Patients younger than 65 undergoing RC had an overall survival of 7 years, compared with 2 years for the TMT group. (p = 0.0001). Conclusions: The Bladder-Preservation method, as a replacement for RC, showed a lower overall survival rate in our study. A prospective randomized clinical trial may declare the best treatment.

Seasonal changes are assumed to affect various sperm characteristics based on photoperiods, temperature, and air pollution. According to the literature, most studies were performed on populations of Western countries, and there are limited studies performed in the Middle East with variable results. This study evaluated the seasonality of sperm characteristics among men of reproductive age in an andrology center in Kerman, Iran, where the seasonal temperature varies significantly, with average temperatures ranging from 50 °F (10 °C) to 75.2 °F (24 °C). We retrospectively evaluated the sperm analysis test record. Sperm samples were obtained from 2,948 men during 10 years, excluding those with azoospermia. Samples were assessed for volume, concentration, motility, and morphology according to the World Health Organization (WHO) criteria. We performed a comprehensive comparative literature review of the studies investigating the association between seasonal variation and sperm quality. The mean semen volume was higher in the summer compared with other seasons (p =.04). The mean percentage of sperm motility was higher in the spring and less in winter (p =.03). Sperm morphology-related parameters, measured by the percent of normal morphology, were significantly better in winter (p =.03). Our findings suggest seasonality of sperm characteristics among men of fertility age. Semen volume, motility, and morphology were affected by the photoperiod of reproductive seasons. Results might support the influential role of seasonal variations in the possibility of fertility, especially among those using assisted reproductive technologies and those with oligospermia.

Purpose: To compare medium-term stone recurrence between laparoscopic pyelolithotomy (LP) and percutaneous nephrolithotomy (PCNL). Material and methods: 98 patients who underwent PCNL or LP (2015-2019) for large single renal pelvis or staghorn stones (≥ 2 cm) were selected. The stone-free rate was evaluated using a computed tomography scan at one month and then, ultrasonography at six months intervals during the first year and annually thereafter for up to three years. Time-to-stone recurrence was compared using the Kaplan-Meier estimate. Hazard ratio was estimated by Cox regression. Results: The one month stone-free rate was 93.88% in the LP group vs. 79% in the PCNL group (P = .03). The mean overall time-to-stone recurrence was 31 (CI:24-34) months in the LP vs. 28 (CI: 23-32) in the PCNL groups (P = .02). Cox regression analysis showed that PCNL increased the risk of stone recurrence with a hazard ratio of 2.3 (CI: 1.1 - 5.3) compared to the laparoscopy. (p = .03) In subgroup analysis, time-to-stone recurrence in those without previous history of intervention was estimated at 31 (CI: 27 to 35) months in the LP vs. 25 (CI:16 to 34) in PCNL groups (= 0.04). Subanalysis with a BMI cutoff of 25 kg/m² showed an overall time-to-stone recurrence of 34 (CI:30 to 37) months in the LP group and 28 (CI:22 to 33) months in the PCNL group (= 0.04) in those with BMI higher than 25 kg/m². Conclusion: Medium-term time to stone recurrence was in favor of LP compared with PCNL for large single renal pelvis or staghorn stones. [ABSTRACT FROM AUTHOR]

Purpose: Evidence suggests that androgens can be involved in the pathogenesis of renal stones. This study aimed at investigating coding region polymorphisms and CAG repeats in androgen receptor (AR) and their association with active renal calcium stone disease. Materials and Methods: Male patients with calcium kidney stones (N = 106) with at least two episodes of stone recurrence or size increase during the past 5 years (ASF) were enrolled from December 2008 to April 2009. Control individuals were recruited after matching for age and gender from healthy individuals without current stone or history of stone disease. Genetic sequencing and single strand conformational polymorphism (SSCP) were used to determine AR polymorphisms in the patients and controls. Results: Two polymorphisms were identified in the AR gene: Silent G to A polymorphism in the first exon of the AR gene and C to G polymorphism in intron 4. CAG repeats ranged from 12 to 37. The C/G polymorphism in intron 4 and CAG repeats were associated with the status of active renal calcium stone disease (all p < 0.05). The CC variant of C/G polymorphism was not observed in patients with stone disease. CAG repeats less than 20 and more than 28 were mostly observed in ASF patients (p < 0.05). Conclusions: CAG repeats and intron 4 C/G polymorphism in the AR gene have an association with renal calcium stone disease. [ABSTRACT FROM AUTHOR]

Purpose: To compare two methods of laparoscopic sacrocolpopexy (LSCP) and sacrospinous ligament fixation (SSLF) in terms of efficacy and safety in the treatment of vaginal apical prolapse. Materials and Methods This prospective, randomized controlled clinical trial was conducted on 32 patients with symptomatic vaginal apical prolapse, referred to the female urology clinic of Kerman University, Iran, during 2018-2019. The patients were re-examined at 12 months after surgery. Objective success was recorded using Pelvic Organ Prolapse Quantification (POP-Q) classification as primary outcome. The subjective success of the methods was determined by the quality-of-life parameters, based on Pelvic Floor Impact Questionnaire (PFIQ-7), Pelvic Floor Distress Inventory (PFDI-20), and Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) scores as secondary outcomes. Moreover, complications were recorded in both groups. Results: The amount of intraoperative bleeding was significantly higher in the SSLF group, compared to the LSCP group (P = 0.01). Persistent pain was observed in two (12%) patients in the LSCP group and five (31%) patients in the SSLF group (P = 0.2). The decrease in the total PFIQ-7 score was in favor of the LSCP group but not statistically significant (p = 0.06). The LSCP group showed bigger improvement in vaginal (p = 0.04) and bowel (p = 0.03) scores. The results of the PISQ-12 and PFDI-20 questionnaires as well as POP-Q examination were not different in two groups. Conclusion: Although the surgical methods of LSCP and SSLF can be equally effective in the treatment of apical prolapse, LSCP appears to be superior to SSLF regarding less bleeding.

Adrenal myelolipoma is a rare benign tumor that is composed of hematopoietic cells and mature fat. Mostly, these nonfunctioning tumors are distinguished incidentally during autopsy or radiologic investigations. Here, we report a case of 46-year-old man presented with nonspecific abdominal pain for one year, who had right adrenal mass with fat density detected by radiologic investigation. Histopathological assessment of right adrenalectomy specimen revealed the diagnosis of adrenal myelolipoma. [ABSTRACT FROM AUTHOR]

Background: The results of studies on the effects of age on spenn parameters are controversial. The aim of this study was to evaluate the association of age and semen par ameters. Methods: hi this study 278 men (32.3±6.5 years, range 19 to 65 years) referred to a private medical laboratory to evaluate couple infertility were included from April 2016 to March 2017. Cases with azospennia were excluded from the current study. hi some cases, the cause of the couple infertility was female factor, which is not addressed in this report. Semen samples were collected using standard methods. We analyzed semen parameter's using computer-assisted sperm analysis. Results: All semen parameters were deteriorating with increasing age; however, only the correlation of age with sperm motility was statistically significant. This con-elation showed a quadratic model with an increasing tr end up to a peak at 32 years and then decreasing (R2=0.024, P=0.03). We divided cases into two age groups and repeated the analysis separately for patients younger than 31 year's (median age of our population) or patients older than 31 years. We found that the semen parameters including count, volume, total motility and vitality showed a negative correlation with age in older patients, however', this correlation was significant only for the total motility (P=0.02). Conclusion: Age has an insignificant impact on sperm count, whereas, Spenn motility showed an increasing trend up to a peak at 32 years and then decreasing significantly. [ABSTRACT FROM AUTHOR]

Perinatal testicular torsion is a rare emergency in a neonate that prompts immediate attention. Bilateral testicular torsion is extremely rare. We report a case of bilateral torsion that presented with unilateral scrotal swelling but significant atrophy and dark discoloration of the contralateral testis that was secondary to asynchronous prenatal torsion. There is no consensus about exploration of the contralateral testis when exploring a case with unilateral testicular torsion. Nevertheless, findings in this case report indicate that bilateral exploration is mandatory in each case of perinatal testicular torsion to evaluate the condition of contralateral testis and fix it to prevent development of future torsion that may result in anorchia.

Introduction: In this study the full sequence of the calcitonin receptor gene (CALCR) in a group of Iranian males suffering from recurrent calcium urinary stones was compared with that of a control group. Methods: Serum and urinary biochemistry related to urolithiasis were evaluated in 105 males diagnosed with recurrent kidney calcium stones and 101 age-matched healthy control males. The polymerase chain reaction single-strand conformation polymorphism method was used to detect new polymorphisms in the CALCR. Results: Nine polymorphisms were detected; seven were in the non-coding and two in the coding region. The T allele associated with the 3′UTR+18C>T polymorphism was observed exclusively in the stone formers. The exact odds ratio for the T allele in this locus for those at risk of stone formation was 36.72 (95% CI 4.95-272.0) (p < 0.001). The mean (standard deviation) urine calcium concentration was 117 (60) mg/l in patients with the C allele and 152 (72) mg/l in those with the T allele (p = 0.03). In addition, IVS1-6T>C and IVS1insA polymorphisms in intron 1 were associated with kidney stone disease (p < 0.001). Regarding single nucleotide polymorphism 447, mean (standard deviation) of serum calcitonin levels were 16.7 (18.7) pg/ml, 10.5 (11.0) pg/ml and 9.94 (9.7) pg/ml in subjects with TT, TC and CC genotypes, respectively (p = 0.01). Conclusion: Our data indicate a potential association between 3′UTR+18C>T and intron 1 polymorphisms in the CALCR and the risk of kidney stone disease. © 2013 S.

PURPOSE: To compare two matched groups of men with bladder transitional cell carcinoma (TCC) who underwent prostate-sparing cystectomy (PSC) or conventional radical cystoprostatectomy (CRC). MATERIALS AND METHODS: Twenty-three men who have undergone PSC with the diagnosis of bladder TCC (Ta-T2) from 2003 to 2008 in Tehran, Iran were included in the study as the experimental group. The control group composed of 27 men with comparable tumor characteristics and age range, who had non-nerve-sparing radical cystoprostatectomy and orthotopic ileal W pouch reconstruction in the same center. All the procedures were performed by the same surgical group under the supervision of different attending staff. RESULTS: Mean follow-up period was 39 months in PSC and 35 months in CRC group. The 5-year overall survival was 47% and 30% in PSC and CRC groups, respectively. Median survival was 48 months in PSC and 36 months in CRC group, using Kaplan-Meier survival analysis (P > .05). Impotence was observed in 16.6% in PSC and in 83.3% in CRC group (P = .002). Mean International Index of Erectile Function-5 score of the PSC group was 19.8 compared with 5.7 in the CRC group (P = .003). Only one patient in each group was completely incontinent. Urethral anastomosis stricture occurred in 2 patients in CRC group. CONCLUSION: Patients who underwent PSC did not show decreased overall survival compared to CRC, which provided better functional results. [ABSTRACT FROM AUTHOR]

Purpose: The prevalence of erectile dysfunction in men is increasing. As well, the prevalence of diabetes, as one of the causes of sexual dysfunction, is rising in many countries. Due to the failure of common therapies in some patients with sexual dysfunction, it is necessary to develop an effective alternative treatment, such as stem cell therapy, for this problem.Materials and Methods: In this randomized single-blinded clinical trial, 20 diabetic patients with erectile dysfunction, who were resistant to common treatments, were selected and divided into two groups of intervention and control (n=10 per group). Autologous mesenchymal stem cells (MSCs) were extracted from oral mucosa and then infused via intracavernosal injection (50-60 ×106 cells) to the participants of the intervention group. Normal saline was injected in the control group. The patients were followed up with the International Index of Erectile Function (IIEF5) questionnaire, as well as color Doppler duplex ultrasound. Peak systolic velocity (PSV), end diastolic velocity (EDV), and resistance index (RI) were determined three and six months after the interventions.Results: The mean IIEF5 scores in the intervention group were 7.2 ± 2.1, 9.2 ± 3.4, and 10.6 ± 4.7 before, three months, and six months after the injection, respectively, showing a significant ascending trend (P = 0.01). Comparing the intervention and control groups, there was a significant difference in the IIEF5 score change during six months after the injection (P = 0.02). Regarding the PSV and RI of penis vessels, there were no statistically significant differences between the two groups. However, these parameters showed upward and improving trends in the intervention group.Conclusion: Intracavernosal injection of stem cells improved sexual function and PSV and RI indices of penile arteries in diabetic patients.

Purpose: To evaluate the safety and efficacy of discharging patients on the first postoperative day after an uncomplicated percutaneous nephrolithotomy (PCNL).Materials and Methods: after an uncomplicated successful PCNL without significant residual stone (>5mm) or any complication up to the first postoperative day, we randomly assigned patients into two groups-Group 1: overnight surgery, and Group 2: routine discharge after three days. Patients with significant residual stone on control fluoroscopy were excluded. Ninety eight and 102 patients were assigned to groups 1 and 2, respectively. Serum Hemoglobin and Cr were evaluated before the operation as well as the first postoperative day. Stone free status was evaluated using ultrasound and KUB radiography at the first postoperative day.Results: The stone and patient characteristics were not different in two groups. The preoperative and change in the hemoglobin and creatinine levels were not significantly different between the two groups. Nine patients (9.2%) in Group 1 and five (4.9%) in Group 2 were readmitted because of complications (mainly hematuria) (p=.23). Of the readmitted patients, five in Group 1 (55%), and three in Group 2 (60%) received blood transfusion (p=.87). in these patients, group 1 received 1.6±0.51 units of blood compared with 1.93±0.25 in group 2 (p=.07). All the readmitted patients did well with conservative therapy with no need for angioembolization.Conclusion: In uncomplicated PCNL with no significant residual stone, discharging the patient on the first postoperative day is safe. The outcome is comparable to a routine three-day hospital stay. [ABSTRACT FROM AUTHOR]

Background: Anesthesia decreases brain cognitive function, memory and pain, and also leads to the loss of consciousness. In this study, midazolam and propofol-sedated trauma patients undergoing lower limb surgery were evaluated for stress levels after neuraxial anesthesia. Materials and methods: This double-blind randomized clinical trial was conducted on patients with lower extremity fractures due to trauma, who were candidates of elective lower extremity orthopedic surgery. Patients were randomly divided into two groups of propofol-sedated patients (n=110) and midazolam-sedated patients (n=110) after neuraxial anesthesia. Then, all patients underwent spinal anesthesia using 3 ml of 0.5% bupivacaine (3 mg/kg). Propofol (25-75 µg/kg/minute) was infused, and 1-2 mg of midazolam was injected PRN until patients reached the score of 3 on the Modified Observers' Assessment of Alertness/Sedation Scale (MOAA/S). Results: Preoperative sedation/alertness scores of patients in the two groups did not differ significantly from one another. Penetrating memories in the midazolam group was higher than the propofol group (P<0.05). Personal relationship problem was more significant in the midazolam group than the propofol group (P<0.05). Inability in controlling emotional feelings was higher in the midazolam group compared to the propofol group (P<0.001). Conclusion: Our findings indicated that a sub-hypnotic dose of propofol provided a superior sedation and amnesia compared to midazolam. Aspects of stress, including penetrating memories, personal relationship problems, inability to control emotional feelings, and lack of depression during spinal anesthesia were better managed by propofol compared to midazolam.

Sleep disturbances have been shown to be associated with diabetes control, but the relation between planned wakings or napping with glycemic indices has not been evaluated yet. This study evaluated the relation between sleep quality, duration, and pattern, including daytime napping of people with diabetes and their glycemic control. Across-sectional correlation research design was used for this study. We enrolled 118 people with type 2 diabetes receiving oral agents without major complications at the Shahid Bahonar Center, Kerman. The age, weight, height, serum HbA1c, as well as other glycemic indices and lipid profile were measured. BMI was also calculated. All participants were requested to fill in the Pittsburgh Sleep Quality Index (PSQI) questionnaire to evaluate their sleep quality. In addition, they were inquired about their sleep schedule during day and night. Pearson correlation and multiple regression analyses were conducted to examine the correlation between HbA1c and sleep pattern variables. The variables were also compared between participants with or without napping using t-test. All analyses were performed with the SPSS version 19 (SPSS, Chicago, IL, USA). The mean age was 58±11 years and mean HbA1c (%) was 7.8±11 (62±13 mmol/mol). Sleep duration and the number of sleep segments significantly predicted HbA1c (F (2,114)=5.232, P=0.007, R2=0.084). A one-hour increment in sleep duration was associated with a 0.174% (1.4 mmol/mol) decrement in HbA1c. PSQI score did not contribute to the regression model. Moreover, participants who napped (66%) had a lower HbA1c (7.6±1) compared to others (8.1±1.3) (P=0.04). We concluded that napping and segmented sleep are associated with a better glycemic control in type 2 diabetes and there is a linear correlation between sleep duration and better glycemic control.
