The present study showed that the early removal of the urethral catheter, and preoperative dementia and/or delirium had significant correlations with POUR. The femoral neck fractures and the surgical procedure used for the hip surgery do not induce damage to the bladder and nerve system related to the voiding function, and the voiding function in all of the patients recovered after short-term intermittent catheterization. Physicians should not place permanent indwelling urethral catheters without carrying out urological assessments.

We report a case of a 33-year-old male with a mixed germ-cell testicular tumor. Postoperative follow-up FDG-PET revealed concentration of FDG in the left inguinal area which is not tumor metastasis or local recurrence but suture reactivity granuloma. In this paper, we reviewed suture granulomas associated with false-positive findings on FDG-PET after surgery. If FDG-PET will be used more frequently in the future, it will be necessary to refrain from using silk thread in order to prevent any unnecessary surgery.

Objectives: To analyze the risk factors of uroseptic shock induced by calculous acute pyelonephritis (APN). Methods: This study included 69 patients (41 were women and 28 were men) who were admitted to our hospital for APN treatment associated with urolithiasis during the period from January 2005 to December 2012. We reviewed the electronic medical records of these patients to analyze risk factors contributing to the development of uroseptic shock from APN in patients with urolithiasis. Results: Urinary drainage with ureteral stent or nephrostomy was carried out in 62 cases. Septic shock requiring vasopressor infusion against circulatory collapse was observed in 25 patients, these patients showed significantly lower serum albumin levels and higher C-reactive protein (CRP) compared to patients who did not exhibit septic shock. Multivariate analysis revealed that serum albumin level and CRP were the significant risk factors for the development of uroseptic shock from calculous APN. Conclusions: Serum albumin level was the significant risk factor for the development of uroseptic shock from calculous APN. Emergency drainage to decompress the obstructed urinary tract is mandatory as an initial urological intervention for the patients with lower serum albumin level.

Urethral duplication is a rare congenital anomaly. We report a 6-year-old male with type IIA2 (Y-type) using Effmann's classification. The accessory urethra, in which a urinary stone existed, arose from the posterior urethra to the scrotum. Because of recurrent urinary tract infection and urinary discharge from the accessory urethra, surgical removal of the accessory urethra through a scrotal incision was performed. At 7-month postoperative follow-up the patient was completely free from urinary incontinence and urinary tract infection.

Background: The experience with uretero-arterial fistulas has been limited. However, the aggressive treatment of pelvic tumors with surgical resection and radiotherapy, along with liberal use of ureteral catheters, has been attributed to an increase in their incidence. Unless they are promptly diagnosed and treated, uretero-arterial fistulas are associated with considerably high rates of morbidity and mortality. Urologists need maintain a high degree of suspicion for uretero-arterial fistula in high-risk patients. We herein present the clinical course of an iliac artery-uretero-colonic fistula.Case Presentation: A 67-year-old woman with a history of colon cancer who underwent laparoscopic high anterior resection in July 2010. A ureteral stent inserted to right ureteral stricture, which developed as a result of local recurrence of the tumor in September 2010. She had undergone chemoradiotherapy, but the lesion had slowly increased in size. During the replacement of the ureteral stent in April 2016, she immediately experienced bladder tamponade, bloody bowel discharge, and hypotension. Contrast CT revealed a complex fistula between the right distal ureter and the right internal iliac artery. Furthermore, contrast medium flowed into the intestinal tract through the tumor. The patient was therefore diagnosed with internal iliac artery-uretero-colonic fistula. Arteriography revealed a right uretero-internal iliac artery fistula, and the embolization of the right internal iliac artery was performed. The right ureteral stent was removed. Her hematuria and bloody bowel discharge disappeared, but right nephrostomy was performed because she presented with acute pyelonephritis to ureteral obstruction.Conclusion: In the present case, the uretero-arterial fistula was caused by the long use of an indwelling stent, chemoradiotherapy, infection, and an increase in the size of the lesion. When a suspected uretero-arterial fistula is accompanied by bloody bowel discharge, we should consider the possibility of traffic to the intestinal tract.
