Erectile dysfunction (ED) in men under the age of 40 was once thought to be entirely psychogenic. Over the last few decades, advances in our understanding of erectile physiology and improvements in diagnostic testing have restructured our understanding of ED and its etiologies. Although psychogenic ED is more prevalent in the younger population, at least 15%–20% of these men have an organic etiology. Organic ED has been shown to be a predictor of increased future morbidity and mortality. As such, a thorough work-up should be employed for any man with complaints of sexual dysfunction. Oftentimes a treatment plan can be formulated after a focused history, physical exam and basic lab-work are conducted. However, in certain complex cases, more testing can be employed. The major organic etiologies can be subdivided into vascular, neurologic, and endocrine. Specific testing should be directed by clinical clues noted during the preliminary evaluation. These tests vary in degree of invasiveness, precision, and at times may not affect treatment. Results should be integrated into the overall clinical picture to assist in diagnosis and help guide therapy.

Introduction Loss of penile length is a recognized and common consequence of Peyronie’s disease (PD). Traction therapy (TT+) has been reported to decrease post-op length loss as well as increase stretched penile length (SPL) prior to surgery. Aim The aim of this study was to study patient outcomes with penile length change and patient satisfaction after surgery following tunica albuginea plication (TAP) and partial plaque excision and grafting (PEG) with or without postoperative TT. Methods Retrospective analysis was performed from our cohort of Peyronie’s reconstructive surgery between 2007 and 2010. SPL was measured dorsally from pubis to corona and recorded at the initial office visit and then compared to most recent postoperative visit. Patients were then stratified by procedure and whether TT was used (TT+ and TT−; TAP N = 52 [27 TT+ and 25 TT−] and PEG N = 59 [36 TT+ and 23 TT−). Traction therapy was initiated for >2 hours a day for 3 months typically starting 3–4 weeks postoperatively. A non-validated mailed questionnaire assessed patient perceptions. Results Mean length change seen in TAP (TT+) was 0.85 cm (0.25–1.75) vs. −0.53 cm (−1.75 to 0.5) in TAP (TT−) (P < 0.001). The mean length change seen in PEG (TT+) was 1.48 cm (0–6) vs. PEG (TT−) 0.24 cm (−1 to 2.5 cm) (P < 0.001). Sixty-one percent of surveys were returned; 85% lost length prior to the initial office evaluation, with an average of −2.5 cm lost. Importantly, in those who used traction, there was no perceived length loss, 58% reported a mean erect length gain of 1.1 cm. However, only 54% of all patients were satisfied with their current erect length. Conclusions Loss of length in men with PD remains a serious concern. It appears that postoperative TT can result in length preservation, and in many, a measured and perceived length gain following correction of the curvature.

Purpose: Cystinuria is a genetic disorder with both autosomal recessive and incompletely dominant inheritance. The disorder disrupts cystine and other dibasic amino acid transport in proximal tubules of the kidney, resulting in recurrent kidney stone formation. Currently, there are no consensus guidelines on evaluation and management of this disease. This article represents the consensus of the author panel and will provide clinicians with a stepwise framework for evaluation and clinical management of patients with cystinuria based on evidence in the existing literature. Materials and Methods: A search of MEDLINE Ò /PubMed Ò and Cochrane databases was performed using the following key words: ''cystine nephrolithiasis,'' ''cystinuria,'' ''penicillamine, cystine,'' and ''tiopronin, cystine.'' In total, as of May 2018, these searches yielded 2335 articles, which were then evaluated for their relevance to the topic of evaluation and management of cystinuria. Evidence was evaluated by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. Results: Twenty-five articles on the topic of cystinuria or cystine nephrolithiasis were deemed suitable for inclusion in this study. The literature supports a logical evaluation process and step-wise treatment approach beginning with conservative measures: fluid intake and dietary modification. If stone formation recurs, proceed to pharmacotherapeutic options by first alkalinizing the urine and then using cystine-binding thiol drugs. Conclusions: The proposed clinical pathways provide a framework for efficient evaluation and treatment of patients with cystinuria, which should improve overall outcomes of this rare, but highly recurrent, form of nephrolithiasis.

Despite targeted prophylaxis patients with fluoroquinolone resistant rectal vault flora have higher odds of infectious complications following transrectal ultrasound guided prostate needle biopsy. In these patients one should consider using other biopsy approaches or techniques to minimize risk.
