Introduction: The outbreak of coronavirus has put additional pressure on the health care systems of many countries; but telemedicine can be an important way to deal with it, especially for people whose health has been affected by the virus. The present study aims to investigate the Implementation of a Tele-urology Program for Reconstructive Urologic Referrals: Initial Results and Patient Satisfaction.

Material and methods: All patients with a history of a urethral reconstructive surgery during last year was entered to our study and two nurses collected data of demographic and past medical history of patients by existed. Telephone visits:Fellowship of reconstructive urology was connected to patients during a phone call and filled the USS-PROM and COVID-19 questionnaires. Face to face visits: All patients were asked to answer the questionnaire about recent exposure and infection by corona virus, recent travel and other risk factors of COVID-19.

Results: Mean of USSPROM scale was calculated as 1.65 (+2.91) with a range of 0-15. Based on categorization for USSPROM scale, 74 patients (94.8%) had mild symptoms while 4 patients (5.1%) had moderate symptoms and needed further medical attention. Four patients with moderate USSPROM score were required to cystoscopic evaluation, which one patient with moderate USSPROM score had severe stricture and candidate for redo urethroplasty. Two other patients need for urethral stricture dilatation. Cost was calculated based on taxi-service fee. Accordingly, the average (+SD) cost for in-person visits to the physician was estimated as 4.80 + 4.32 million Rials. In terms of distance, the average distance for receiving medical services according to the patient`s residence area was 373.2 +348.79 kilometres.In terms of the patient`s opinion regarding virtual examination, inappropriateness of virtual visits for physical examination, and patient`s inability to explain the problem correctly, patient`s condition at the time of the virtual visit were the main challenges reported by the respondent.

Conclusion: Considering that the present COVID-19 emergency will likely last for months, telehealth could be the safest way to deliver urological care for a large percentage of the patients, such as those who are more at risk of unfavorable outcomes of COVID-19.

Purpose: Prostate cancer (PCa) is the second most commonly diagnosed cancer and the sixth leading cause of cancer death among men worldwide. Biomarkers are an important tool in the early detection of PCa. Prostate-specific antigen (PSA) is one of the oldest biomarkers for the early detection of PCa. Digital rectal exam (DRE) is another screening test for PCa detection, which is considered as an irritating experience for patients. Biopsy is still the most reliable method for PCa diagnosis; however, patients are prone to complications. Therefore, developing non-invasive and accurate methods for PCa screening seems urgent to avoid unnecessary biopsies. There has been remarkable development in PCa molecular biomarkers discovery, largely through progress in omics technologies. Due to the many benefits of liquid biopsies, a significant set of PCa diagnostic kits have been developed using urine samples. Despite the unique benefits of these kits, there are still many challenges to their widespread use in clinics. Here, we have reviewed the latest developments of PCa biomarkers in liquid biopsies.

Methods: Literature on biomarkers for diagnosis of PCa was reviewed during the past two decades.

Results: PSA, PHI, PCA3, and 4K score are among the commonly used markers for PCa diagnosis which have been used over a long-moderate length of time with multiple studies on their performance. We performed a review of their performance. Newer markers are among RNA and DNA markers. Multiple non-coding RNAs (mi-RNAs) were reviewed and their performance on Pca diagnosis was reviewed. Long noncoding RNAs (Lnc RNAs) including PlncRNA-1, HOTAIR, SchLAP-1, MALAT1, MEG3, and PRCAT17.3 were summarized. mRNA markers including TMPRSS2:ERG, and HOXC6 were presented. DNA-based markers including PTEN, HOXB13, and BRCA2 were reviewed. Finally, the use of CircRNAs was reviewed for PCa diagnosis.

Conclusion: Many reviewed RNA-based biomarkers have promising results in the diagnosis of PCa.

Purpose: Three-Dimensional (3D) could help for planning and creating an optimal access route in percutaneous nephrolithotomy (PCNL) procedure by achieving a more accurate approach to the renal collecting system and stone treatment while decreasing the risk of complications. The aim of our study is to compare the efficacy of 3D imaging technique with standard fluoroscopy method as a guiding tool for renal stone location while striving to reduce intra-operative X-ray exposure in the former method.

Materials and methods: This randomised clinical trial enrolled 48 PCNL candidates who were referred to Sina Hospital (Tehran, Iran). Participants were divided into two equal groups of intervention (3D virtual reconstruction) and control, using block randomization method. Age, sex, stone type and location, X-ray exposure during the procedure, stone access accuracy rate and the necessity of blood transfusion during surgery were taken into account.

Results: The Mean age of participants (n = 48) was 46.4 ± 4.8 years, 34 (70.8%) were male, 27 (56.3%) had partial staghorn stones and all participants had stones within the lower calyx. The radiation exposure time, stone access time and stone size were 2.99 ± 1.81 seconds, 272.3 ± 108.9 seconds and 23.06 ± 2.28 mm, respectively. In the intervention group, the accuracy rate for lower calyceal stone access was 91.5%. Also, X-ray exposure and time to stone access were significantly lower in the intervention group compared to the controls (P < 0.001).

Conclusion: We concluded that the utilization of 3D technology in the pre-operative location of renal calculi in PCNL candidates may result in a significant improvement in the accuracy and time to access the renal calculi, as well as reduction in X-ray exposure.

Purpose: Prostate cancer is among the most central sources of cancer-related mortalities. In order to find novel candidates for therapeutic strategies in this kind of cancer, we developed an in-silico method for identification of competing endogenous RNA network.

Methods: According to the microarray data analyses between prostate tumor and normal specimens, we attained 1312 differentially expressed (DE)mRNAs, including 778 down-regulated DEmRNAs (such as CXCL13 and BMP5) and 584 up-regulated DEmRNAs (such as OR51E2 and LUZP2), 39 DElncRNAs, including 10 down-regulated DElncRNAs (such as UBXN10-AS1 and FENDRR) and 29 up-regulated DElncRNAs (such as PCA3 and LINC00992) and 10 DEmiRNAs, including 2 down-regulated DEmiRNAs (such as MIR675 and MIR1908) and 8 up-regulated DEmiRNAs (such as MIR6773 and MIR4683).

Results: We constructed the ceRNA network between these transcripts. We also evaluated the related signaling pathways and the significance of these RNAs in prediction of survival of patients with prostate cancer.

Conclusion: This study provides novel candidates for construction of specific treatment routes for prostate cancer.

Purpose: It is unclear if robotic radical cystectomy with extracorporeal urinary diversion (eRARC) provides additional benefit when performed along with enhanced recovery after surgery (ERAS). We assessed the additional efficacy of eRARC in terms of perioperative outcomes.

Materials and methods: We retrospectively assessed 143 patients undergoing radical cystectomy with urinary diversion between June 2010 and December 2021 at a single center. The patients were assigned to three groups: open radical cystectomy (ORC) with conventional recovery after surgery (CRAS) [Group A], ORC with ERAS [Group B], and eRARC with ERAS [Group C]. A propensity score-matched analysis was performed to evaluate how ERAS and eRARC affected outcomes respectively. Meanwhile, multivariable analysis was used to detect the predictors of prolonged length of hospital stay (LOS).

Results: The median LOS was shorter after ERAS and eRARC. In the propensity score-matched analysis, ERAS was linked to a significantly shorter median LOS (28.0 vs. 20.0 days, P < .001), but eRARC was not associated with a shorter LOS (19.0 vs. 17.5 days, P = .21). Neither ERAS nor eRARC were connected with a reduce in complication rate. Following multivariable analysis, ERAS was found to be independently associated with shorter LOS (OR=0.23, P < .001), but eRARC demonstrated no such correlation (OR=0.29, P = .096).

Conclusion: ERAS had strong association with shorter LOS, although eRARC did not contribute to additional efficacy. Neither ERAS nor eRARC decreased the complication rate.

Purpose: Penile cancer is a rare malignancy, where extranodal extension in inguinal or pelvic lymph nodes is associated with decreased 5-year cancer-survival rate in this study, we try to assess survival and quality of life in a penile cancer patient with bulky lymph node.

Methods: We retrospectively reviewed data from penile cancer patients with bulky lymph nodes who underwent treatment between July 2016 and July 2021 at tertiary referral hospital care. The inclusion criteria (age >18 yr, histologically proven penile cancer, and completion of last treatment 6 months prior to this study) yielded a cohort of 20 eligible penile cancer patients with bulky lymph nodes (> 4 cm/bilateral mobile/unilateral fixed). Only patients who had completed therapy at least 6 months prior to the study were included. After obtaining consent, they were asked to complete the EORTC QLQ-C30 questionnaire to evaluate the patient's quality of life.

Results: Out of 20 patients, 5 patients underwent direct ILND and 15 patients underwent chemotherapy. Median follow-up after primary diagnosis was 114+32 months in patients with early ILND and 52+11 months in patients who underwent delayed lymph node dissection. Out of 5 patients who underwent early ILND, all of them survived during follow-up, and achieved cancer-free status without residual tumor and with excellent functional outcomes (Karnofsky 90). There was no significant difference in social function (p-value = 0.551), physical function (p-value = 0.272), role function (p-value = 0.546), emotional function (p-value = 0.551), cognitive function (p-value = 0.453), and global health status (p-value = 0.893) between patient which treated with early ILND and Neoadjuvant Chemotherapy. However, patients who underwent early ILND showed a relatively better clinical outcome.

Conclusion: Early ILND followed by adjuvant chemotherapy for penile cancer with palpable lymph nodes is more favourable than neoadjuvant TIP chemotherapy.

Purpose: To compare the effects of RALP and LRP on health-related QoL following radical prostatectomy, focusing on studies performed via validated QoL questionnaires measuring particularly general health-related QoL.

Material and methods: A systematic search was conducted using Web of Science, PubMed (MEDLINE) on 15 January 2023 with the following search terms solely or in combination: "robotic radical prostatectomy", "laparoscopic radical prostatectomy," and "quality of life". After retrieving the titles and abstracts of selected articles, the full texts of related articles were screened.

Results: After full-text evaluation, among 185 articles, 23 articles were found eligible for inclusion. Hoze et al. reported that the global health status at the 12th month of the surgery was almost the same in both groups according to EORTC- QLQ-C30 scores (76.3 in the RALRP group vs. 76.1 in the LRP group). Wang et al. reported a 75 point of EORTC-QOL-C30 global health status ten years after LRP. Wyler et al. found that the 1-3 month EORTC-QLQ-C30 global health score was significantly worser than the baseline score, 65.3±18.3 vs. 77.2±18.2; however, it returned to baseline in 13-24 months (77.7±16.8) even proceed baseline score in experienced hands at 49-58 months follow up, 78.2±17.8 vs. 85.3±15.5. The frequently used patient-reported quality of life questionnaire following RALRP was EORTC-QLQ.

Conclusion: Both robotic-assisted and laparoscopic radical prostatectomy are valid treatment options to achieve a good quality of life following surgery. The intermediate and long-term results in regard to QoL are comparable between the two procedures. RALRP might be superior to LRP in terms of immediate health-related quality of life, which might contribute to early recovery of urinary function.

Purpose: To investigate the effect of pyeloplasty in pediatric patients with poor function kidneys, focusing on the split renal function (SRF) and anteroposterior diameter (APD) of the renal pelvis.

Materials and methods: A retrospective study included 47 pediatric patients with ureteropelvic junction obstruction (UPJO) who underwent open pyeloplasty with SRF< 20%. All patients were recruited from the Labbafinejad University Hospital center from April 2014 to October 2020. The results of preoperative ultrasonography and Diethylenetriamine pentaacetate (DTPA) scan compared with the results of the ultrasonography and DTPA scan 6 months and one year after surgery. Finally, Wilcoxon signed-rank test was used to test differences the SPSS (version 25) software statistical computer package.

Results: The mean age of participants was 1.5 years. There were 34 cases with SRF between 10% and 20%, and 13 cases with SRF < 10%. The findings showed that pyeloplasty for UPJO leads to a significant improvement in renal function in poorly functioning renal units with 10% ≤ SRF < 20%. Although improvement in renal function occurred in the group with SRF of less than 10%, it was not statistically significant. The APD in both groups was statistically significantly improved. No correlation between genders and outcomes was found.

Conclusion: Poorly functioning renal unit (SRF < 20%) can show functional improvement after the pyeloplasty.

Purpose: Recent studies have provided reliable evidence for a relationship between loss of PTEN gene expression and prognosis in patients suffering from prostate cancer, although the results have been somewhat diverse in different populations. We aimed to assess PTEN gene expression loss by immunohistochemistry in prostate cancer and also its link to tumor upgrading in a group of affected patients undergoing radical prostatectomy.

Materials and methods: This cross-sectional study was performed on 58 tissue samples sourced from the patients with prostate cancer and undergoing radical prostatectomy. TRUS-guided needle biopsies of the cancer tissue samples with histological grade groups of I to IV (the Gleason scores of 6 to 8) were prepared as the study samples. 29 patients with Gleason score (6 to 8) whose tumors on needle biopsy upgraded to Gleason score 7, 8 or 9 at prostatectomy (cases) were compared with 29 patients with Gleason scores of 6, 7 or 8 on both biopsy and prostatectomy samples (controls). Immunohistochemistry (IHC) technique was employed to determine PTEN gene expression status.

Results: Loss of PTEN gene expression was found in 62.1% of upgraded cases compared with 27.6% of controls, indicating a statistically significant difference, revealing a meaningful association between the loss of PTEN gene expression and tumor upgrading. Furthermore, we demonstrated that deletions of PTEN gene expression and increased Gleason score in control and upgraded case groups, did not reach statistical significance.

Conclusion: A high rate of PTEN gene expression loss can be detected in prostate cancer tumor tissue, and this loss of gene expression is associated with tumor upgrading.
