A 52-year-old patient presented with a ruptured abdominal aortic aneurysm after bicycle trauma. He was treated with a vascular prosthesis. His postoperative recovery was complicated by acute renal failure with anuria for which he was commenced on dialysis. His main persistent symptoms were severe abdominal pain, nausea and vomiting as well as massive ascites. Despite several attempts of a diagnostic and therapeutic ascitic tap, we were initially unable to make a diagnosis. Following each attempted paracentesis, symptoms initially improved. Ascites did reaccumulate, however, and we had to continue with his dialysis. Measurement of creatinine in the ascitic fluid was the key to the correct diagnosis. The ascitic fluid creatinine was nearly 3 times higher than the serum creatinine. The consequent MRI scan of the abdomen with excretion urogram demonstrated a leakage of the left ureter at the junction of the proximal and the middle third of the ureter with contrast leaking into the surrounding fluid.

Three nulliparous women, aged 39, 34 and 26 years, who were treated for fertility problems and who were affected by endometriosis, presented with ureteral obstruction caused by deep infiltrating endometriosis. The first two patients had complete unilateral loss of kidney function at the time of diagnosis. They chose to have fertility treatment first and both became pregnant. The third patient still had 24% renal function in the affected left kidney. She was treated by complete surgical resection of the endometriosis and reimplantation of the ureter. Ureteral obstruction is a rare, but serious, complication of deep infiltrating endometriosis. Timely recognition is important, since delay results in unnoticed loss of renal function. Clinical investigation for endometriosis of the posterior vaginal fornix is recommended for all patients with chronic abdominal pain, severe dysmenorrhoea or deep dyspareunia. On diagnosis of deep infiltrating endometriosis, further examination is necessary to detect possible ureteral obstruction and consequent hydronephrosis, which can be demonstrated by ultrasound. MRI is of value to map the extent of disease, which is usually multi-focal. Surgery to relieve ureteral obstruction and remove all endometriotic lesions is the treatment of choice if the kidney is still functional.

Endometriosis is a disease of the uterus with displacement of endometrium-like tissue outside the endometrium. Endometriosis is a common benign chronic often debilitating disease that primarily affects young woman. The estimated prevalence is about 10 %. In addition to the uterus and ovaries, clinically important localisations are the rectovaginal space, rectum, sigmoid colon, urinary bladder, ureter and peritoneum. The most common localisation outside the pelvis is the abdominal wall. Today, MRI is one of the most important tools in the diagnosis of endometriosis. The detection of peritoneal manifestations and the exact definition of the depth of infiltration in the rectum, sigmoid colon and bladder walls are limitations of MRI.

We report a case of Herlyn-Werner-Wunderlich syndrome diagnosed in the neonatal period. US revealed the classic association of a uterus didelphys with blind hemivagina and no ipsilateral kidney. The diagnosis was established by postnatal US and confirmed by MRI. Differential diagnoses are discussed. A trans-hymeneal resection of the vaginal septum was performed at 1 month of age. Intra operative endoscopy revealed no left hemitrigone but showed an atretic orifice in the ipsilateral blind hemivagina, probably corresponding to the insertion of an ectopic ureter. Follow-up was unremarkable.

Primary adenocarcinoma of the ureter occurs in only <1%. Furthermore, metastatic carcinoma to the ureter is very rare and has been described to occur from breast, lung, stomach and prostate cancers. However, metastases to the ureter from colon cancers are extremely rare, and have been largely reported as incidental post-mortem cases. We describe two cases of asymptomatic ureteric metastases secondary to adenocarcinoma of the colon; one is synchronous, whilst the other is a metachronous ureteric metastasis. With the increasing use of radiological imaging modalities such as CT and MRI (Clin Imaging 2001;25:197-202, 2001), together with increasing survival rates of primary cancers, asymptomatic ureteric metastases are more likely to be diagnosed. In summary, metastatic ureteric carcinoma of colonic origin must be considered as a differential diagnosis when there is a radiological abnormality of the ureter in patients with a history of adenocarcinoma of the colon. This should be considered even in patients with colon adenocarcinoma who have previously undergone adjuvant chemotherapy with curative intent.

We present a case of leiomyosarcoma of the right ovarian vein with MRI findings. The patient was a 52-year-old woman who had suffered from right flank pain for one week. Abdominal ultrasound and excretory urography revealed hydronephrosis of the right kidney. Ureteroscopy showed external compression at the right upper third of the ureter. CT and MRI of the abdomen revealed a retroperitoneal mass with compression of the right ureter. The retroperitoneal mass proved on histology to be a leiomyosarcoma arising from the right ovarian vein.

A 11-year-old boy showed gross hematuria and left flank pain. Ultrasonography and CT revealed left hydroureteronephrosis, and he was referred to us for the further evaluation. MRI revealed left hydroureteronephrosis with filling defect at the distal end of the dilated ureter suggesting ureteral polyp. Open surgery was performed with the diagnosis of mid-ureteral obstruction. In the operative findings, multiple stalks of ureteral polyps arose from the entire ureteral wall over 5 cm in length at the site of ureteral obstruction. Mid-ureter with polyps was completely resected, and end-to-end anastomosis was performed. The pathological diagnosis was fibroepithelial polyp of the ureter.

We report the case of a sacral neurinoma, which presented with mild hydronephrosis, due to compression of the right ureter, in a 71-yr old woman admitted to our hospital with recurrent urinary tract infections. CT and MRI detected a 4 x 4 cm mass pressing on the right ureter at the sacral level, in continuity with the second sacral foramen. Given this finding, the mass was thought to be of presumable neurogenic origin. In order to both reach a conclusive diagnosis and relieve the compression of the ureter, a laparoscopic resection of the mass was performed. Surgery was successful and the pathologic examination revealed a sacral Antoni A neurinoma. Neurinomas, also called Schwannomas, are uncommon benign nerve sheath tumors arising from Schwann cells. Their diagnosis can be extremely difficult due to their aspecific symptoms and the lack of pathognomonic characteristics on imaging exams. Therefore, histopathologic evaluation is essential in establishing the diagnosis. Surgical resection seems to be the best approach, both for diagnostic and therapeutic purposes.

Our case report pertains to a 32-year-old woman initially presenting with left flank pain and gross haematuria throughout her urinary stream. CT of her kidney/ureter/bladder (CT KUB) revealed ureteric dilatation to the level of the bladder without evidence of renal calculus and subsequently a stent was inserted. She represented a month later with contralateral flank pain, and a transuretheral resection of bladder tumour was performed. Histopathological diagnosis was epithelioid angiosarcoma. Further imaging (MRI pelvis) revealed that the tumour arose from the posterior bladder wall with local invasion and regional lymph node metastasis. Ifosfamide and epirubicin chemotherapy with single-fraction radiotherapy induced significant reduction in tumour bulk, although this initial response was followed by the development of symptoms suggestive of disease progression. She died 19 months after initial diagnosis with persistent pulmonary and vertebral metastases although no autopsy was performed.

Symptomatic Mullerian duct cysts are uncommon. A young adult male presented to us with a palpable supra-pubic mass, pain and lower urinary tract symptoms. Initial imaging modalities showed a large cystic lesion in the pelvis with a non-visualized right kidney. A short, blind ending right ureter on retrograde pyelography added to the confusion. On exploration, the lesion was noted to be separate from the seminal vesicles, bladder and posterior urethra. The right kidney was absent. The cystic lesion was excised completely preserving the vas and seminal vesicles. A high index of suspicion is needed for identification of this rare condition. Use of MRI (magnetic resonance imaging) can help improve the diagnostic accuracy. Many a times though, the diagnosis is evident only on exploration.
