ABSTRACT
We report a case of ureteral migration of a surgical clip after partial nephrectomy in which the clip was misdiagnosed as a ureteral stone. A 37-year-old woman had undergone laparoscopic partial nephrectomy of right renal cell carcinoma at another hospital 2 years previously. Postoperatively, she had gradually acquired lower urinary tract symptoms. Then, she complained of sudden right flank pain for a week. A plain X-ray and enhanced abdominopelvic computed tomography scan were performed. A 0.5 cmx1.0 cm right upper ureteral opacity with borderline hydronephrosis was seen but could not be found on the X-ray. Ureteroscopy revealed a medium-sized Hem-o-Lok clip on the right upper ureter that was removed with a stone basket. We concluded that a Hem-o-Lok clip used for collecting system sealing had migrated to the ureter and had been misdiagnosed as a ureteral stone on a computed tomography scan.

A previously healthy 44-year-old woman, with no notable medical history developed left flank pain. To rule out left renal infarction, enhanced abdominal computed tomography(CT) was done and a wedge shaped hypointense lesion was identified in the left posteromedial aspect of the interpolar region. Renal angiography revealed an isolated renal artery dissection that was causing renal infarction due to narrowing of the main stem of the left renal artery. The patient experienced pain with severe uncontrolled hypertension. The patient was successfully treated by percutaneous angioplasty and renal artery stenting.

Lymphoepithelioma was originally described as a neoplasm in the nasopharynx. Tumors with histologic features similar to those of nasopharyngeal lymphoepithelioma have been identified in anatomic sites other than the nasopharynx, such as the salivary gland, lung, thymus and stomach; these tumors have been termed lymphoepithelioma-like carcinoma(LELC). The etiology and pathogenesis of this neoplasm in the renal pelvis is not clear. We have experienced a case of lymphoepithelioma-like carcinoma of the renal pelvis and we report here on this along with a brief review of the relevant literature.

ABSTRACT
The occurrence of bladder tumors in the first 2 decades of life are rare neoplasias. Transitional cell tumors of the bladder are extremely a rare clinical disease entity. Here, a case of a papillary urothelial tumor in a 5-year-old girl is reported, with a brief review of the literature. Histologically, the tumor was a solitary and papillary urothelial tumor of low malignant potential (by WHO and the ISUP).

Endometriosis represents extrauterine nonneoplastic endometrial tissue. It is most commonly diagnosed in women of childbearing age, with a peak age of 40 to 44 years. The incidence of genitourinary involvement ranges from 1% to 2%. Ureteral endometriosis is a rare entity, and its diagnosis requires a high index of suspicion. We report a case of ureteral endometriosis in a 44-year-old multiparous woman with a brief review of literature.
