A New Technique for Simple Renal Cyst: Cystoretroperitoneal Shunt

Purpose. To evaluate the results of patient symptoms and radiologic outcomes of cystoretroperitoneal shunt (CRS) technique in the treatment of symptomatic simple renal cysts. Patients and Methods. In a prospective study, 37 patients with a simple renal cyst were treated with ultrasound-guided percutaneous CRS-catheter. Radiological success was indicated as no recurrence of the cyst or a reduction in cyst volume by at least half. Results. CRS technique was performed successfully in 36 patients with a simple renal cyst. The mean size of all cysts decreased from 8.8 cm (range 7 to 14) to 1.7 cm (range 0 to 9; P < .001). Symptomatic success (pain relief) was achieved in 29/36 (80.5%) of patients, and radiographic success was achieved in 23/36 (63.8%) of patients, with a median follow-up of 16 months (range 6 to 24). Conclusion. Ultrasound-guided percutaneous CRS technique for simple renal cysts is fast, safe, effective, and inexpensive

European Society for Sexual Medicine Consensus Statement on the Use of the Cavernous Nerve Injury Rodent Model to Study Postradical Prostatectomy Erectile Dysfunction

Introduction: Rodent animal models are currently the most used in vivo model in translational studies looking into the pathophysiology of erectile dysfunction after nerve-sparing radical prostatectomy. Aim: This European Society for Sexual Medicine (ESSM) statement aims to guide scientists toward utilization of the rodent model in an appropriate, timely, and proficient fashion. Methods: MEDLINE and EMBASE databases were searched for basic science studies, using a rodent animal model, looking into the consequence of pelvic nerve injury on erectile function. Main outcome measures: The authors present a consensus on how to best perform experiments with this rodent model, the details of the technique, and highlight possible pitfalls. Results: Owing to the specific issue—basic science—Oxford 2011 Levels of Evidence criteria cannot be applied. However, ESSM statements on this topic will be provided in which we summarize the ESSM position on various aspects of the model such as the use of the Animal Research Reporting In Vivo Experiments guideline and the of common range parameter for nerve stimulation. We also highlighted the translational limits of the model. Conclusion: The following statements were formulated as a suggestive guidance for scientists using the cavernous nerve injury model. With this, we hope to standardize and further improve the quality of research in this field. It must be noted that this model has its limitations

Extracorporeal transient distal penile corporoglanular shunt in early ischemic priapism treatment

Purpose Ischemic priapism, which is a compartment syndrome, needs urgent treatment in order to nourish corpora cavernosa. As the first step, the aspiration of blood and/or the irrigation of the cavernosal bodies are performed to prevent fibrotic activity and secure erectile capability. While performing aspiration and irrigation, there are some risks of the procedure in which most refrained one is cardiovascular side effects of adrenergic agonists. We aimed to evaluate extracorporeal transient distal penile corporoglanular shunt technique in place of aspiration/ irrigation techniques for early ischemic priapism treatment. Materials and Methods In this transient shunt technique, a sterile closed system blood collection set (BD Vacutainer, Cat. No.: 367282; NJ, USA), which has two 21G needles, was used. The length of the needle and tubing was 19 mm. (0.75 inch) and 178 mm. (7 inches), respectively. This blood collection set was designed to be used not only for blood collection but can also be used for short term infusions (maximum 2 hours). Results Ten patients out of fifteen with early ischemic priapism were successfully treated with this transient shunt technique. The permanent detumescence achieved in the first 10 minutes in nine out of fifteen patients. No additional procedure needed after the disappearance of rigidity in successfully treated patients. The permanent detumescence achieved in the first 10 minutes in nine out of fifteen patients. Conclusions We demonstrated that this extracorporeal transient shunt technique gets some advantages over aspiration and irrigation in early ischemic priapism treatment. Our results indicate that the presented technique to be offered for the patients with an ischemic priapism episode of no more than 7 hours
