Injection of triamcinolone significantly reduced stricture recurrence after internal urethrotomy. Further investigations are warranted to confirm its efficacy and safety.
To evaluate the efficacy of sildenafil in the treatment of neurogenic erectile dysfunction (ED) secondary to upper motor neuron (UMN) and lower motor neuron (LMN) spinal cord injury (SCI). After taking consents 105 patients suffering from ED were enrolled in this prospective study. Seventy-two patients had signs and symptoms of UMN and 33 patients had signs and symptoms of LMN or mixed (UMN and LMN) spinal cord injuries. The patients took 50-100 mg sildenafil or placebo tablet at least 45 min before sexual intercourse. Based on a IIEF questionnaire, success in achieving erection adequate for sexual intercourse was compared between sildenafil and placebo groups in UMN and non-UMN spinal cord injuries. In patients with UMN disease, sildenafil was effective in 82% of patients and its efficacy was statistically higher than placebo (82 vs. 25%, p < 0.05). Twenty-eight per cent of patients with non-UMN disease had a favourable response to sildenafil that was not statistically different from placebo. Sildenafil seems more effective in the treatment of neurogenic ED secondary to UMN spinal cord injury compared with that secondary to LMN injury. Actually, its efficacy on LMN injuries does not seem different from placebo and administration of this treatment may not be effective in spinal cord injury which has caused LMN symptoms.
Local blockade of the obturator nerve during cystoscopy is an effective method to avoid its stimulation in TURBT. It can be performed easily, and we did not experience any serious complication.
Transvesical ONB is a safe and effective method of ONB before TURBT. This method is feasible by urologists and promising even without nerve stimulation and only by anatomic landmarks.
Sandostatin caused a marked decrease in mucus production by the intestinal segment with patients receiving Sandostatin no longer requiring routine postoperative bladder irrigation and having a shorter hospital stay.
Background:Tumor growth requires expansion and development of vascular network. An increase in Gleason score is representative of an increase in tumor invasion and extent. In this study, the relationship between Gleason score and vascular characteristics of needle biopsy samples in prostate cancer patients has been evaluated.Materials and Methods:We evaluated vascular characteristics including density and size of vessels; and percentage of vessels with irregular shape in 62 cancer-positive samples obtained by prostate needle biopsy under ultrasound guide, and compared them to Gleason score.Result:Gleason scores of 23 patients were ≤6; Gleason scores of 18 patients were 7 and 21 patients had their Gleason score from 8 to 10. An increase in Gleason score was associated with increased vascular density (P < 0.0001), increased percentage of vessels with irregular shape (P < 0.02) and decreased average vascular diameter (P < 0.015), from which the relationship with vascular density was clearer and more evident.Conclusion:Vascular morphological characteristics can be representative of angiogenic potential of prostate cancer which is required for tumor progression. As Gleason score can prognosticate the behavioral characteristics of prostate cancer in future, vascular characteristics may also be able to express tumor behavior. With attention to vascular characteristics in biopsy samples and apart from Gleason score, we may also be able to divide patients into other subtypes in a way being helpful for the establishment of treatment plan.
Background. The objective of this study was to evaluate the efficacy of adding single doses of ceftriaxone and amikacin to a ciprofloxacin plus metronidazole regimen on the reduction of infectious complications following transrectal ultrasound-guided prostate biopsy (TRUS Bx). Materials and Methods. Four hundred and fifty patients who were candidates for TRUS Bx were divided into two groups of 225 each. The control group received ciprofloxacin 500 mg orally every 12 hours together with metronidazole 500 mg orally every 8 hours from the day prior to the procedure until the fifth postoperative day. In the second group, single doses of ceftriaxone 1 g by intravenous infusion and amikacin 5 mg/kg intramuscularly were administered 30–60 minutes before TRUS Bx in addition to the oral antimicrobials described for group 1. The incidence of infection was compared between the groups. Results. The incidence of infectious complications in the intervention group was significantly lower than that in the control group (4.6% versus 0.9%, p = 0.017). Conclusion. The addition of single doses of intramuscular amikacin and intravenously infused ceftriaxone to our prophylactic regimen of ciprofloxacin plus metronidazole resulted in a statistically significant reduction of infectious complications following TRUS Bx.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
