Ectopic ureteral orifice presents predominantly in young girls with duplicated kidneys and ureters, and mostly drains from ectopic ureters were associated with non-duplicated upper urinary systems and it is called a single system ectopic ureter. It is frequently associated with renal dysplasia or agenesis and ureterocele. Compared with ectopic ureter draining from the duplicated kidney, the diagnosis of single system ectopic ureter is often delayed because the ectopic ureter may be associated with a single small dysplastic, poorly functioning kidney. We report a case of single system ectopic ureter associated with dysplastic and poorly functioning kidney.

Renal cell carcinoma can presents wide range of signs and symptoms, and commonly associated with paraneoplastic syndrome. Paraneoplastic manifestations are present in up to 20% of patients with renal cell carcinoma. There is convincing evidence that renal cell carcinoma tumor cells elaborate proteins that serve as mediators of endocrine (ex ; ectopic production of parathyroid hormone-related protein or erythropoietin) as well as nonendocrine paraneoplastic syndromes. A paraneoplastic syndrome may be the various clinical presentation of renal cell carcinoma in a significant number of patients, therefore mimicked other general disease. We report a case of renal cell carcinoma associated with paraneoplastic syndrome mimicking pyelonephritis.

A case of a female subject with a unilateral vaginal ectopic ureter associated with a single system, ipsilateral hypoplastic pelvic kidney and bicornuate uterus is reported. Although there are many reports of concomitant urinary and reproductive system malformations, a review of the literature shows these unique associations in the same patient to be extremely rare. This malformation is not limited to any combination of abnormal development of the mesonephric(wolffian) and paramesonephric(mllerian) ducts in the development of the urogenital system. Embryological aspects as well as clinical presentation, diagndstic approach and treatment applicable to this case are discussed.

A 41-year-old male visited Ewha womans university hospital with the symptom of frequency, dysuria and residual urine sensation. We could find a Mullerian duct cyst by Transrectal ultrasonography(TRUS) and MRI image. Mullerian duct cyst was incised by transutricular seminal vesiculoscopy(TUS). The symptom was decreased significantly after surgical treatment. Presently, We report this case with a review of the Mullerian duct cyst.
