Objectives

This systematic review and meta-analysis study aimed to examine the relationship between infertility and sleep quality in women.

Methods

The literature search was conducted between October and November 2022 with full-text studies from PubMed (MEDLINE), Cochrane, Google Scholar, and Scientific Information Database (SID). The study is based on the recommendations of the Cochrane guidelines. The data were analyzed using the Review Manager computer software (Version 5.3).

Results

A systematic literature review was conducted, with 11 studies included. The meta-analysis revealed a significant difference between infertility and sleep quality in women, that the sleep quality of infertile patients decreased (SMD: −0.75 95% CI: −0.84 to −0.66, Z = 16.46, P < .00001), and that there was a significant difference between infertility and depression (SMD: −0.18 95% CI: −0.27 to −0.09, Z = 4.00, P < .0001).

Conclusion

The results of this study indicate that sleep quality is low in infertile women.

PROSPERO ID: (CRD42023404389).

Objective

To compare the performance of the risk calculators of the European Randomized Study for Screening of Prostate Cancer (ERSPC) and the Prostate Biopsy Collaborative Group (PBCG) in predicting the risk of presenting clinically significant prostate cancer.

Material and methods

Retrospectively, patients who underwent prostate biopsy at Sanatorio Allende Cerro, Ciudad de Córdoba, Argentina, were identified from January 2018 to December 2021. The probability of having prostate cancer was calculated with the two calculators separately and then the results were compared to establish which of the two performed better. For this, areas under the curve (AUC) were analyzed.

Results

250 patients were included, 140 (56%) presented prostate cancer, of which 92 (65.71%) had clinically significant prostate cancer (Gleason score ≥7). The patients who presented cancer were older, had a higher prostate-specific antigen (PSA) value, and had a smaller prostate size. The AUC to predict the probability of having clinically significant prostate cancer was 0.79 and 0.73 for PBCG-RC and ERSPC-RC respectively (P = 0.0084).

Conclusion

In this cohort of patients, both prostate cancer risk calculators performed well in predicting clinically significant prostate cancer risk, although the PBCG-RC showed better accuracy.

Introduction

Infertility is one of the important phenomena in human reproduction. Genetic factors are the most important cause of male infertility. Here, we aimed to investigate the correlation between idiopathic male infertility and SNPs of the LHCGR (rs2293275) and NR5A1 (rs1057517779) genes in the Iranian-Azeri population.

Methods

This case-control study consisted of 100 males with infertility and 100 healthy males from the Iranian Azeri population. Genomic DNA isolation from whole blood samples and Tetra-primer amplification refractory mutation system-polymerase chain reaction (Tetra-ARMS-PCR) method was used for genotyping. The data analysis was performed by chi-square (χ2) and Fisher’s exact tests.

Results

Genotyping analysis for LHCGR (rs2293275) polymorphism indicated that the frequency of C in the case group was significantly higher than in the control group (P < .05). Moreover, genotyping analysis for NR5A1 (rs1057517779) polymorphism indicated that the frequencies of the A allele and heterozygote GA genotype in the case group were significantly higher than those in the control group (P < .05).

Conclusion

Our study demonstrated that the SNPs of LHCGR (rs2293275) and NR5A1 (rs1057517779) genes may play a critical role in male infertility in the Iranian Azeri population. However, further studies on other ethnic origins with larger sample sizes are essential for accessing more accurate results. Moreover, functional experiments might be needed to understand the role of these polymorphisms in the molecular pathways involved in male fertility.

Introduction

Due to their increasing prevalence and complex management, renal tumors are challenging for health professionals. The study aims to evaluate the usefulness of R.E.N.A.L. and PADUA nephrometry scores in the prediction of complications after percutaneous cryoablation.

Material and methods

The study prospectively analyzed 90 patients with 101 stage T1a renal cell carcinoma (RCC) tumors treated with cryoablation.

Results

Ninety patients with 101 small renal tumors who received cryoablative therapy were investigated. The mean age of the patients was 68 years and 74.4% were male. Most tumors were smaller than 4 cm (89.1%) and the mean PADUA and R.E.N.A.L. scores were 8.65 and 7.35, respectively. Complications were observed in 12 cases. PADUA and R.E.N.A.L. scores demonstrated moderate predictive power (AUC = 0.58 and AUC = 0.63, respectively) for post-cryoablation complications.

Conclusions

Percutaneous cryoablation is a safe and effective treatment for small renal tumors. The R.E.N.A.L. and PADUA renal nephrometry scores have moderate predictive power for complications associated with percutaneous cryoablation of renal tumors.

Introduction

The aim of this study is to evaluate and compare erection function (EF) after Excision and Primary Anastomosis Urethroplasty (EPAU) and Buccal Mucosal Graft Urethroplasty (BMGU) in bulbar urethral stricture.

Methods

Patients who underwent urethroplasty were identified retrospectively. The criteria for inclusion in the study were determined as being over 18 years old and under 70 years old, being sexually active. Exclusion criteria are; preoperative severe erectile dysfunction, stricture outside the bulbar urethra, psychosocial incompatibility, urethral stricture related to pelvic fracture, follow-up time less than a year. As the primary endpoint, the International Index of Erectile Function-5 (IIEF-5) was determined as a comparison of EF in the preoperative and third, sixth and twelfth months after surgery. The secondary endpoint was the evaluation of the effects of demographic data, stricture and treatment characteristics on EF.

Results

Fifty patients were identified considering the inclusion/exclusion criteria. It was observed that there were 30 patients who underwent EPAU and 20 patients who underwent BMGU. At the third month after surgery, EF showed a statistically significant decrease in the EPAU group. In both patient groups, it was observed that the early negative effects after the operation in EF started to improve in the sixth month and returned to the baseline level by the first year.

Conclusion

EPAU and BMGU techniques have a similar effect on EF in the medium and long term. Both methods can be used safely and effectively in the appropriate patient group.

Introduction and objectives

Transplant renal artery stenosis (TRAS) is a vascular complication after kidney transplantation which estimated incidence is 13%. It could cause refractory arterial hypertension, kidney dysfunction and premature death in transplant recipients.

Methods

We carried out a retrospective study including every patient who underwent renal transplantation between 2014 and 2020. They were evaluated with a systematic post-transplant renal Doppler ultrasound. To identify independent risk factors for transplant renal artery stenosis we performed a multivariate analysis.

Results

Seven hundred twenty-four kidney transplants were included, 12% ​​were living donors and 88% were deceased donors. The mean age was 54.8 in recipients and 53 in donors. Transplant renal artery stenosis was diagnosed in 70 (10%) recipients, the majority in the first 6 months after surgery. 51% of patients with transplant renal artery stenosis were managed conservatively. The multivariate analysis showed diabetes mellitus, graft rejection, arterial resuture and donor body mass index as independent risk factors for transplant renal artery stenosis. Survival of the grafts with transplant renal artery stenosis was 98% at 6 months and 95% at two years.

Conclusions

The systematic performance of Doppler ultrasound in the immediate post-transplant period diagnosed 10% of transplant renal artery stenosis in our cohort. Despite the above risk factors, an adequate monitoring and treatment could avoid the increased risk of graft loss in patients with transplant renal artery stenosis.

Introduction and aim

Patients treated with HoLEP are frequently treated with previous treatments, including 5-alpha-reductase inhibitors (5-ARIs). We investigated the impact of pretreatment with 5-ARIs on perioperative and immediate postoperative parameters in patients treated with HoLEP.

Material and methods

A retrospective study was performed using a prospectively collected database including all patients treated with HoLEP at our center between January 2017 and January 2023. The resected tissue weight, enucleation and morcellation efficiency (enucleation weight/time and morcellation weight/ time), postoperative complications, hospital stay and hemoglobin drop have been analyzed.

Results

A total of 327 patients were included. Of these, 173 (52.9%) were treated with 5-ARIs. No differences were found among the perioperative parameters investigated to determine efficiency. No differences were observed in peri- or postoperative complications, hospital stay or hemoglobin drop.

Conclusions

Therapy with 5-ARIs had no impact on the immediate postoperative outcomes of patients treated with HoLEP. In our cohort, we observed that the use of 5-ARIs did not affect surgical efficiency, enucleation or morcellation. Further multicenter studies will be necessary to validate these findings.
