Ureteral injuries are uncommon but serious complications of laparoscopic pelvic surgery. When unrecognized, patients experience fever, abdominal pain, signs of peritonitis, and leukocytosis usually 48 to 72 hours after the surgical procedure. A 48-year-old woman underwent laparoscopic-assisted vaginal hysterectomy, bilateral salpingo-oophorectomy, and anterior and posterior colporrhapy due to a large, symptomatic uterine myoma. Postoperatively, she suffered from progressive left lower quadrant pain, with drainage of yellowish fluid from the subumbilical puncture wound 5 days after the operation. Significant urinary ascites was present. Intravenous pyelogram revealed injury to the lower third of the left ureter about 3 cm away from the ureterovesical junction. Left-sided percutaneous nephrostomy was performed after transurethral placement of a ureteral stent failed. Reanastomosis of the ureter was performed successfully 3 months later, and the patient fully recovered without compromise of the genitourinary tract.

The primary presentation of congenital megaureter in adults is rare. Development of urolithiasis may lead to this unusual underlying diagnosis. Urinary tract stones can form either within the dilated ureteral segment or in a part of the upper urinary tract proximal to the abnormal ureteral segment. We report two cases of nephrolithiasis that occurred in adults found to have segmental megaureter. The first case is that of a 58-year-old man who presented with left lower quadrant pain. Computed tomography scan revealed a 2-cm stone in the distal left ureter within an area of isolated segmental distal ureteral dilation. The second case is a 48-year-old man who developed recurrent renal urolithiasis associated with isolated distal megaureter.Although a rare condition in adults, congenital megaureter may present when kidney stones develop as a result of the ureteral abnormality. Typically, stones will develop within the dilated segment of ureter. Atypically, stones may develop away from the site of the underlying abnormality. Congenital megaureter is a diagnosis that urologists and radiologists need to consider in the setting of isolated distal ureteral dilation, as the diagnosis of adult megaureter may require more involved surgical measures to prevent recurrence of adverse symptoms.

Isolated aneurysms of the iliac artery (IA) are very rare. Inflammatory aneurysms are also rare conditions, making the association rarer. Only four cases of isolated inflammatory IA aneurysms have been reported in the last decade. In this article, we report a case of a 62-year-old patient with a 13-cm large isolated inflammatory aneurysm of the left common IA associated with a 2.5-cm right common IA involvement. The patient presented with a left lower quadrant pain, a pulsatile mass with bruit, as well as a left hydronephrosis secondary to the ipsilateral ureter entrapment, and a motor and sensory deficit of the left lower extremity. An aortoiliofemoral prosthetic repair associated to a left to right ureteral transposition was undertaken with an approach including a laparotomy and bilateral femoral artery exposure. The postoperative period was uneventful. The case mentioned in this study is probably the largest IA aneurysm ever described.

A 79-year-old woman with a history of diabetes mellitus and recurrent urinary tract infections (UTIs) presented with acute onset left lower quadrant pain, left-sided back pain, vomiting, and dysuria. Abdominopelvic CT scan revealed left hydroureteronephrosis to the level of the left ureterovesical junction (UVJ) where a bladder mass appeared to be obstructing the left ureteral orifice. The obstruction was ultimately found to be the result of a sloughed renal papilla lodged in the distal ureter, which created an inflammatory mass at the UVJ. Her history of diabetes and frequent UTIs likely predisposed her to the development of renal papillary necrosis (RPN) that resulted in sloughing of a renal papilla, distal ureteral obstruction with subsequent bladder inflammation that mimicked a bladder mass on imaging. RPN is a condition associated with many etiologies and likely represents a common final pathway of several diseases. Although several hypotheses exist, it is primarily thought to be ischemic in nature and is related to the underlying physiology of the renal papillae. We present a case of hydroureteronephrosis and bladder mass secondary to a sloughed renal papilla from RPN.
