Retroperitoneal fibrosis is associated with fibroblast proliferation due to inflammatory changes in adipose/fibrous tissue. Given that aortic dilation in abdominal aortic aneurysm can cause compression of the ureter, abdominal aortic aneurysm complicated by retroperitoneal fibrosis is likely to result in urinary tract obstruction. Accordingly, close attention to changes in perioperative urine v...

Background: For the narrow ureter that will not accommodate a ureteroscope, it is common practice to place a ureteral stent, to allow subsequent ureteroscopy in the passively dilated ureter. Surprisingly, there are limited data on the effectiveness or safety of these maneuvers. Methods: We retrospectively analyzed patients managed with ureteral stent placement followed by another attempt at ure...

PURPOSE Temporary drainage of the upper urinary tract by use of internal ureteral stents is a common procedure that is often associated with a variety of symptoms. The role of intravesical stent position in associated morbidity is controversial. MATERIALS AND METHODS The German version of the ureteral stent symptom questionnaire (USSQ) was completed by 73 patients with an indwelling ureteral ...

OBJECTIVE To compare the incidence of iatrogenic ureteral injury between laparoscopic and open colectomies at a single institution. DESIGN From June 1, 2005, through July 31, 2010, patients were identified from a prospectively maintained database and hospital records were retrospectively reviewed. SETTING Mount Sinai Medical Center. PATIENTS Fourteen patients who underwent colectomy compl...

The patient was a 51-year-old lady with left flank colicky pain accompanied with nausea and vomiting for a month. Transurethral lithotripsy and ureteral stent placement was considered for the patient. The patient had a narrow ureteral lumen and while bringing the ureteroscope out, ureteral avulsion occurred at a distance approximately 4 cm from ureteropelvic junction. After bringing the uretros...

PURPOSE There is some debate over the necessity of ureteral stenting after laparoscopic ureterolithotomy. We evaluated the need for ureteral stenting after retroperitoneal laparoscopic ureterolithotomy (RLU). MATERIALS AND METHODS Between January 2009 and January 2013, 41 patients underwent RLU to remove upper ureteral stones. The retroperitoneal approach was used in all patients by a single ...

To evaluate the impact of ureteral stenting history to the outcomes of extracorporeal shockwave lithotripsy, we retrospectively analysed patients who underwent shockwave lithotripsy with Dornier Gemini lithotripter between September 2010 and August 2012. Forty seven patients (group A) who had a double J stent which was removed just before the procedure were matched-paired with another 47 patien...

A 67-year-old male renal transplant patient presented with a right inguinal bulging mass, and was diagnosed with a right indirect inguinal hernia. The day following inguinal herniorrhaphy, serum creatinine became elevated. The patient was oliguric and had abdominal pain on the first day after inguinal herniorrhaphy with a mesh. We diagnosed him with acute renal failure and subsequently performe...

INTRODUCTION AND OBJECTIVE Indwelling double J ureteral stents are used routinely in the resolution of ureteral obstruction caused by different etiologies. Evaluation of urinary symptoms related to double-J stent, indicate that these affect 73-90% of patients. We conducted a prospective, randomized study, to evaluate the efficacy of tamsulosin, oxybutinin and combination therapy in improving th...

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 morbid...
