Introduction: Benign prostatic hyperplasia, bladder outlet obstruction, and overactive bladder are major causes of lower urinary tract symptoms (LUTS). Tumor compression of the urinary bladder resulting in LUTS was clinically observed. Gastrointestinal stromal tumors (GISTs) presenting with LUTS have not been reported before. Herein, we report a patient with extraluminal GIST of the ileum who had LUTS without gastrointestinal symptoms during the clinical course., Patient Concerns: A 68-year-old man visited the genitourinary outpatient department because of frequent urination with mild dysuria. He also complained of poor appetite, fatigue, and body weight loss of 10 kg over 6 months. A large presacral solid mass lesion compressing the bladder and surrounded by the bowel with gas content was identified through abdominal computed tomography., Diagnosis: GIST of the ileum with mesenteric invasion was revealed by pathological examination., Interventions: Exploratory laparotomy with removal of the pelvic tumor and segmental resection of the ileum was performed., Outcomes: Now, he received adjuvant imatinib target therapy for 1 year with stable condition., Conclusion: Extravesical compression or invasion of the urinary bladder by a pelvic mass lesion is common but is rarely accompanied by GISTs of the ileum. Specific findings identified through imaging should alert the surgeon to this specific entity and prepare thoroughly before surgical intervention.

At present, robot-assisted radical prostatectomy (RARP) is a gold standard in radical prostatectomy. The aim of this study was to evaluate the incidence, risk factors, and timing of occurrence of inguinal hernia (IH) after RARP.We included 427 patients with prostate cancer who underwent RARP by a single surgeon from February 2006 to August 2017. Incidence, clinical, and pathological factors were investigated to assess relationship with the development of IH.Postoperative IH occurred in 29 cases (6.79% of all RARP patients), whereas 22 cases (75.9% of all IH patients) occurred within the first 2 years. The median follow-up period was 5.2 years, and the median age of patients was 65 years. Postoperative IH occurrence was significantly associated with body mass index (BMI), smoking history, and low surgeon experience (P = .036, .023, and .048, respectively). However, low surgeon experience did not reach statistical significance after multivariate analysis.The overall incidence of IH after RARP was significantly associated with BMI and smoking history. With obvious incidence of IH within the first 2 years after operation which was not observed at the open prostatectomy, RARP itself may play a role in the development of IH.

Rationale: Urethral hemangiomas commonly occur in men or elderly women. We presented a rare case of urethral hemangioma in a prepubertal female patient., Patients Concerns: An 8-year-old girl had the complaints of bloody staining of clothing, a foul perineal odor, and urethral pain. She was brought to our genitourinary outpatient department for survey and a single, 1-cm compressible reddish nodule at the 10-2 o'clock position in the distal urethra was found., Diagnoses: Urethral hemangioma in a prepubertal girl was diagnosed after excision of the urethral nodule., Interventions: Excision with 8 "stay" sutures in the protruding urethral mucosa was performed., Outcomes: Normal micturition without symptom recurrence was noted at the 3-month follow-up., Lessons: Urethral hemangioma is also found in prepubertal female patient. Increased physician awareness and early recognition of a urethral hemangioma can avoid unnecessary examinations and patient anxiety. The procedure of excision with 8 "stay" sutures in the protruding urethral mucosa facilitates mobilization from the distal urethra and provides a good surgical view of abnormal proliferative blood vessels. Therefore, the lesion can be removed as clean as possible.

Background: Plasmacytoid urothelial carcinoma (PUC) is a distinct variant of urinary bladder cancer, with a high propensity for invasion and poor prognosis. These tumors occur most commonly in male patients with the age of reported cases ranging from 46 to 87 years., Case Report: We present a case of a 74-year-old male patient having massive ascites and bilateral lower leg edema. Colonoscopy showed a 3-cm lesion in the sigmoid colon and an edematous nonpapillary tumor was found by cystoscopy in the bladder. Histopathology analysis of the biopsies showed adenocarcinoma of colon and PUC of bladder. The diagnosis of PUC with peritoneal carcinomatosis was then confirmed by immunohistochemical stain., Conclusion: The diagnostic dilemmas of the unusual variant of urothelial malignancy, the origin of peritoneal metastasis, and its clinical impact are discussed in the present case.

Introduction: Emphysematous epididymo-orchitis is a rare cause of acute scrotum pain characterized by gas formation within the tissue. Diabetes mellitus and recto-seminal fistula secondary to sigmoid diverticulitis are generally accepted as being responsible for this disease. However, prostate invasion secondary to rectal cancer may be considered to be a newly identified pathogenetic mechanism. Herein, we report this rare case and illustrate the pathogenesis., Case Presentation: A 69-year-old man arrived at our emergency department presenting with sepsis and acute scrotal pain. Emphysematous epididymo-orchitis was diagnosed by scrotal sonography initially; however, advanced rectal cancer with prostate invasion was diagnosed by CT after a recurrent episode. An exploratory laparotomy with abdominoperineal resection and radical prostectomy were performed after neoadjuvant chemoradiotherapy. Histopathologic analysis confirmed the previous diagnosis. Emphysematous epididymo-orchitis caused by advanced rectal cancer is very rare, and our case is the first to be reported according to a literature search. Neoadjuvant chemoradiotherapy plus extended surgery can achieve a good oncological outcome., Conclusion: This case indicated that the very rare presentation as emphysematous epididymo-orchitis caused by locally advanced colorectal cancer., Competing Interests: The authors have no conflicts of interest to disclose.
