Among all, α-blocker tamsulosin has been used widely. In contrast silodosin which is recently introduced in the market and more selective alpha-receptor antagonist and cardioselective drug but it has not been used widely as MET. In this study, silodosin (8 mg), tamsulosin (0.4 mg), and oral hydration therapy were compared in terms of efficacy and safety as MET in the management of ureteric stone along with rate of stone clearance, expulsion time, analgesic requirements, and adverse effects for treating ureteral stones size between ≥4 mm and ≤10 mm in diameter. Materials and Methods: Prospective randomized study was conducted between September 2018 and August 2020 with a total of 240 patients (80 patients in each arm) in tertiary care center of eastern India. First group received a single dose of silodosin (8 mg) daily, second group received a single dose of tamsulosin (0.4 mg) daily and third group received oral hydration therapy for 4 weeks. Results: There is no difference in the stone expulsion rate (SER), stone expulsion time (SET), and surgical intervention between tamsulosin, silodosin and oral hydration therapy group for ureteric stones ≤5 mm size. For ureteric stones of size 6 mm–10 mm, silodosin has better SER than tamsulosin with no difference in terms of SET. Analgesic requirement and pain episodes were more in the oral hydration group with no adverse effects (statistically significant). Conclusion: The proportion of passed-out stone was significantly higher among the patients treated with silodosin (65.0%) in comparison to other two groups (P < 0.05) with no difference in SET.","PeriodicalId":23449,"journal":{"name":"Urological Science","volume":"33 1","pages":"19 - 25"},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43173135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: Patients who received transperineal anastomotic repair of PFUDDs from January 2007 to December 2019 were retrospectively analyzed, specifically focusing on demographic findings, pelvic fracture type, urethral distraction defect length (based on retrograde urethrography and cystography), previous treatments, and ancillary maneuvers during surgery. Simultaneously, differences in clinical factors between successful and failed cases were also analyzed. Results: A total of 36 patients were included, with a final success rate of 83%. The mean age was 40.4 years, whereas the mean urethral distraction defect length was 31.9 mm. Most patients (69%) presented with unstable pelvic fractures. Treatment before referral included endoscopic treatment and urethroplasty in 13 (36%) and 2 cases (6%), respectively. For difficult cases, ancillary procedures, which included corporeal splitting (61.1%) and inferior pubectomy (8.3%), were performed. The postoperative average peak flow rate was 14.9 mL/s in the success group. Age and urethral defect length differed significantly between the success and failure groups.

The major corresponding biological molecular mechanisms of Li-ESWT are to induce stem cell differentiation, neural regeneration, and angiogenesis. This narrative review aims to present an overview of the potential utility of Li-ESWT and its effects on stem cell therapies. Recent studies have also shown that the combination treatment of Li-ESWT and stem cell therapies can be a new option for the treatment of erectile dysfunction (ED), urinary incontinence, bladder dysfunction, and other diseases. The potential contributions of Li-ESWT on stem cell therapies for these diseases are studied, highlighting the influence of Li-ESWT on proliferation, viability, and differentiation capacity of certain stem cells. The potential mechanisms, including the increased expression of vascular endothelial growth factor, chemokine CXC motif ligand 5, and transforming growth factor-β1 are described herein. Li-ESWT can also activate many cellular signaling pathways. The combination of Li-ESWT and stem cell therapies is a promising strategy for urological diseases. However, a much greater understanding of the mechanisms by which Li-ESWT enhances the efficacy of stem cell therapy is still needed before this combined treatment can be recommended for large-scale clinical application.","PeriodicalId":23449,"journal":{"name":"Urological Science","volume":"33 1","pages":"3 - 8"},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44483644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: Between October 2004 and October 2015, our institute had 350 patients who underwent retroperitoneoscopic nephroureterectomy for possible upper urinary tract urothelial carcinoma without a routine diagnostic ureteroscopy (URS) or ureteroscopic biopsy. Trauma, urolithiasis, or infection were excluded. We collected imaging findings; urine cytology results; renal function status; previous urothelial history; and the final pathology results. Twenty-three (6.6%) patients had nonmalignant benign lesions found from pathology. Results: The 23 patients comprised nine men and fourteen women. Most patients were middle-aged. Initial symptoms included gross hematuria, hydronephrosis, and flank pain. From self-voided urine cytology, the most common result was atypical cells. The number of patients was equal in the end-stage renal disease (ESRD) plus postkidney transplantation group and the non-ESRD group. In addition, we divided patients into two groups according to lesioned kidney function status: Nonfunctional kidney (NFK) or functional kidney (FK). The most common pathologic feature found in the NFK group was atrophic kidneys. On the other hand, the most common diagnosis in the FK group was pyelonephritis. Conclusion: Nonmalignant pathologic lesions were detected in 23 patients who had undergone retroperitoneoscopic nephroureterectomy without preoperative diagnostic URS for upper tract lesions. Self-voided urine cytology provided limited information for diagnosis in this group. For the almost 75% of patients with NFK, nephroureterectomy may be a feasible diagnostic and therapeutic method.","PeriodicalId":23449,"journal":{"name":"Urological Science","volume":"32 1","pages":"151 - 156"},"PeriodicalIF":0.5,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48768474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Improper collection compromises the quality of data attained in molecular and functional assays due to the increased quantities of degraded proteins and RNA. We sought to improve the methods for tissue collection which can avoid generating considerable loss in the viability of cells for further analyses. Materials and Methods: Fifty resected tumor samples from 35 patients were obtained with different surgical techniques and at various time points for viability and RNA quality evaluation. The degradation of RNA was evaluated by its Qubit IQ score, OD 260/280 ratio, total yield, and quantity of β-actin. Results: Snap-frozen tissue samples obtained within 30 min showed better cell viability (P < 0.0001), RNA total yield (P = 0.0081), Qubit ratio (P = 0.003), OD 260/280 ratio (P = 0.4213), and quantity of β-actin (P = 0.0015). Moreover, the bladder tumor samples collected from transurethral biopsy presented more satisfied cell viability results than the ones resected by transurethral electroresection (P < 0.0001). Conclusion: Tumor samples should be processed or frozen freshly within 30 min once removed from human body. Furthermore, transurethral biopsy of bladder tumor is considered a better method for collecting samples for further molecular oncology studies. The high-quality RNA produced enable researchers to conduct more reliable studies by avoiding the experimental artifacts due to the presence of cellular debris or dead cells.","PeriodicalId":23449,"journal":{"name":"Urological Science","volume":"32 1","pages":"186 - 192"},"PeriodicalIF":0.5,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46889803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The axial ureteral length (AUL) and coronal ureteral length (CUL) were derived from measurements made on the CTU images, and the length of each patient-specific ureteral stent was chosen based on the calculated ureteral length. Results: Overall, 105 ureters were measured: 54 (51.4%) right side and 51 (48.6%) left side ureters. The mean CUL and AUL of right ureters were 22.5 ± 2.3 cm and 22.5 ± 2.3 cm, respectively, whereas the mean CUL and AUL of left ureters were 23.6 ± 2.2 cm and 23.4 ± 2.1 cm, respectively. Pearson correlation analysis showed that body height was significantly correlated with ureteric length (right CUL and patient height: r =0.441, P = 0.001; right AUL and patient height: R = 0.445, P = 0.001; left CUL: R = 0.341, P = 0.029; left AUL: R = 0.339, P = 0.015). Thirteen of 57 patients underwent ureteral stent insertion; none experienced stent migration (upward or downward) before the removal of the ureteral stent. Comparison of proposed stent size with actual stent size in the 13 patients shows the percentage of size appropriateness (as defined by concordance between proposed and actual stent length) to be 76.9% (10/13).

Enrollees who underwent conventional semen analysis and an SDF test for medical purposes or elective examinations were enrolled. SDF ≥20% was regarded as abnormal. Spearman correlation coefficient was used to determine the correlations. Area under the receiver operating characteristic curve area under the curve (AUC) was calculated to determine the predictive value.

Results: In total, 90 men were enrolled, of whom 44 (48.89%) visited for infertility and 51 (56.67%) had abnormal semen analysis. Immotile sperm (IM) and nonprogressive sperm (NPS, NPS = nonprogressive motility + IM) were significantly correlated with SDF (r = 0.50, P < 0.001 for NPS; r = 0.49, P < 0.001 for IM) and were the most predictive for abnormal SDF (AUC = 0.77 for NPS; AUC = 0.78 for IM). By using Youden index, the cutoff values for the prediction of abnormal SDF were 66.37% for NPS and 48.73% for IM.
