Objective: To present a well-organized review about ureteral access sheath impact on ureteral injury. Materials and Methods: Systemic search on literature was done. Total of 3766 studies observed by two urologists and results were unified. A Prisma diagram was used for eliminating irrelevant studies and at the end of elimination process 28 studies were found eligible for this review. Results: Not only clinical studies but also comparative experimental animal studies show that there is no significant data to claim that ureteral access sheath insertion causes more ureteral injury. Pre-stented patients were found to be at lower risk for ureteral injury. Risk of progression to ureteral injury seems to be low even if ureteral injury occurs with insertion of ureteral access sheath. Conclusion: Summary of studies' results indicate that use of ureteral access sheath doesn't increase ureteral injury. This review may help understanding safety profile of ureteral access sheath on evidence-based level. There is not enough data to make a statement that ureteral access sheath prevents ureteral injury.
Objective: To investigate the efficiency of three advanced lithotripters during the treatment of artificial stones (hard and soft) in an experimental in vitro and in vivo setting. Materials and Methods: An experimental configuration was created to treat artificial stones, made from BegoStone Plus in a weight ratio of 15:3 or 15:6 powder to water, replicating hard and soft urinary stones, respectively. Experimental data of three lithotripters, the Lithoclast Master, the Lithoclast Trilogy, and the ShockPulse-SE, were assessed. Experiments aimed at comparing the stone clearance times (SCTs) of the devices as well as different probe diameters, probe disposability, and hardness of the stones. The in vivo experiment was performed in a porcine model after the approval from the State Services. Before in vivo lithotripsy, stones had been placed through percutaneous access established by using the Bull's eye technique. The SCT between the Lithoclast Trilogy and the ShockPulse-SE was compared. Results: All the devices were statistically more efficient in the treatment of soft stones in both in vitro ( p < 0.001) and in vivo settings ( p < 0.008). The use of larger-diameter probes resulted in shorter SCT ( p < 0.007). The disposable probes of the ShockPulse-SE showed higher performance than the multiple-use probes ( p < 0.05). In the direct comparison between the devices, the Lithoclast Trilogy was found to be the fastest during all the in vitro ( p < 0.001) and in vivo ( p < 0.008) trials. Conclusion: Modern dual - energy lithotripters proved to possess high performance in the treatment of stones. Faster SCTs were observed by using the larger-diameter and disposable probes. The Lithoclast Trilogy was superior in terms of SCT over all the experimental settings compared with other lithotripters.
Bladder malignancy represents the fourth most common cancer in men and the eighth in women in the western world. Women under 75 years of age have a risk of 0.5–1% of developing bladder cancer. The diagnosis usually occurs between 65 and 70 years of age, whereas the mortality rate for women varies from 0.5 to 4 per 100,000 every year. Nulliparous women present a greater risk than women who have given birth. The risk is further decreased when parity increases. Theoretically, hormonal changes occurring during pregnancy play a protective role. Smoking and occupational exposure to specific chemicals are the most common risk factors of bladder cancer. Other risk factors such as chronic urinary tract inflammation, cyclophosphamide, radiotherapy, and familial correlation have been reported. The aim of this review is to highlight a rare combination, which is the co-existence of bladder malignancy and pregnancy. We present thirteen different cases of women who were diagnosed with malignant bladder tumors during their pregnancy. A review of the literature was conducted, focusing on the unspecific symptoms, possible diagnostic tools, and suitable treatment modalities. The management of bladder cancer in pregnancy is a challenging process. The fragile balance between the possible complications of pregnancy and maternal health is yet to be discussed.
Inflatable penile prosthesis (IPP) surgery is an effective treatment for erectile dysfunction (ED), but infections pose a significant threat to its success. Current guidelines lack antifungal recommendations, despite rising fungal infection rates post-IPP surgery. This review examines epidemiology, risk factors (including diabetes mellitus, immunosuppression, and obesity), and pathogenesis, highlighting the role of biofilm formation in device contamination. Clinical manifestations vary from acute to delayed, with fungal biofilms presenting challenges in diagnosis. Prophylactic strategies, including broad-spectrum antibiotics and antifungals, are crucial, with evidence suggesting a 92% reduction in infections. With fungal infections showing lower salvage rates, management involves culture-guided treatment, irrigation, and oral antibiotics. Future research aims to understand biofilm mechanisms and develop biomaterials to reduce infection rates. Implementing antifungal therapy, along with standard practices like the no-touch technique and antibiotic dips, is crucial in preventing IPP infections.
Purpose: The aim of this study is the evaluation of the distribution of paclitaxel (PTX) released by a coated balloon in the layers of rabbit’s urethra.Methods: 18 rabbits were included. A laser device was used for the stricture formation. After two weeks, dilation of the strictured urethra was performed by using Advance 35LP PTA balloons and Advance 18 PTX PTA balloons. The experimental models were divided into 3 groups. The group Α included two rabbits without any intervention except for the stenosis procedure. Group B compromised six rabbits that underwent dilation with Advance 35LP PTA balloons. Group C consisted of 10 rabbits to which dilation with both Advance 35LP PTA balloons and Advance 18 PTX PTA balloons was applied. Histological evaluation and Immunohistochemistry were performed on all specimens.Results: Inflammation, fibrosis and ruptures were detected in the specimens of the study. In specimens of Group C the decrease of inflammation and fibrosis rate was greater. Anti-PTX antibody was detected in the epithelium, lamina propria and smooth muscle layer of all specimens of urethras that have been harvested immediately and 1 day after the dilation with Advance 18 PTX PTA balloon and it was not observed in any layer of the urethral wall of the rest of the examined specimens of Group C.Conclusions: PTX’s enrichment was detected in the smooth muscle layer of all specimens that have been harvested immediately and 24h after the dilation with Advance 18 PTX PTA balloons. PTX may play an inhibitive role in the recurrence of the stenosis.
