    ABSTRACT: Myelolipomas are rare tumors consisting of both adipose and hematopoietic tissue and are typically found within the adrenal gland. Extra-adrenal involvement is rare, especially those tumors involving the perirenal space and collecting system. We report a case of a patient with an incidentally discovered perirenal mass that was initially concerning for a retroperitoneal liposarcoma. Following surgical resection and pathological analysis, the lesion was found to be an extra-adrenal myelolipoma. This case report and review of the literature demonstrates the importance of the proper work-up and management of perirenal lipoma variants while addressing the issues of tissue biopsy, surgical intervention, and pre- and post-operative surveillance.

    ABSTRACT: Urinary fistulae develop as abnormal connections between the gastrointestinal (GI) and genitourinary (GU) tracts, and occur in multiple disease processes including diverticulitis, malignancy, and Crohn's disease. Crohn's disease is now the most common cause of fistula formation between the ileum and bladder and the third most common cause of fistulae between the colon and the bladder. Few articles provide a comprehensive review of this process. We performed a PubMed search using such terms as "fistula" and "Crohn's disease" and/or "enterovesical fistula." We reviewed references from selected papers and relevant articles were used for information-gathering and cited accordingly. Fistulae in Crohn's disease generally occur due to preformed abscess formation or bowel perforation from the development of aphthous ulcers. The most common type of urinary fistula is enterovesical, due to the close proximity of the ileum and bladder dome. Computed tomography and cystoscopy are the most common diagnostic tools utilized. Surgical treatment is usually definitive; however medical treatment has been used with some success as well. Urinary fistulae represent an uncommon, yet serious problem to patients with Crohn's disease. Patient symptoms and imaging direct the practitioner to proper diagnosis, with direct visualization via cystoscopy confirming the presence of a urinary fistula. Treatment is aimed at relieving symptoms and may be medical or surgical depending on the clinical presentation.

    ABSTRACT: Sacral neuromodulation (SNM) has become a standard treatment option for patients suffering from urinary urge incontinence, urgency-frequency, and/or nonobstructive urinary retention refractory to conservative and pharmacologic treatment. Since its initial development, the manufacturer of InterStim therapy (Medtronic, Inc., Minneapolis, MN, USA), has introduced technical modifications, while surgeons and researchers have adapted and published various innovations and alterations of the implantation technique. In this article, we feature our SNM technique including patient selection, comprehensive dialogue/evaluation, procedure details, and appropriate follow up. Although there is often great variability in patients with lower urinary tract dysfunction, we maintain that great success can be achieved with a systematic and methodical approach to SNM.

    ABSTRACT: Testicular ischemia is typically seen with cases of testicular torsion. Twisting of the spermatic cord and compromise of testicular blood supply can induce testicular loss if not promptly discovered and treated. Non-torsion causes of testicular ischemia are uncommon with rare citations in the literature. Herein, we present a case of testicular ischemia induced by traumatic thrombosis of the spermatic vessels.

    ABSTRACT: Exercise and physical activity have been linked to the prevention of certain types of cancer such as colon and breast. As prostate cancer is the most common malignancy diagnosed in the male population, there is obvious interest in determining a possible effect of exercise on disease prevention and improvement of disease-related outcomes. Thus far, data has been conflicting and there has been no clear determination of prostate cancer prevention through exercise. However, as prostate cancer treatment carries many side effects which may be bothersome and health-threatening, researchers have examined the effects of exercise training on reducing treatment-related complications and improving outcomes and quality of life (QOL). In this review, we discuss the impact of exercise on reducing side effects of prostate cancer treatment and improving cancer-specific and overall survival outcomes, as well as improving QOL in prostate cancer patients.

    ABSTRACT: Testicular torsion is an emergent condition requiring prompt surgical intervention to avoid permanent testicular compromise and death. As its symptoms overlap with other disease processes, diagnosis is sometimes difficult. When considering the presenting symptoms, one must be careful not to ignore unusual causes of torsion and misdiagnose the patient. In this case report we describe an unusual etiology of testicular torsion (traumatic) with an atypical patient presentation (mildly painful) which presented many obstacles before proper diagnosis and treatment.
