Leiomyoma of urinary bladder: report of a case

A case of leiomyoma of the urinary bladder in a 46-year-old woman is reported. The patient was referred to us because of incidental finding of a mass in the bladder. Cystoscopy revealed a protruding tumor covered with normal-appearing urothelium on the right posterior wall of the bladder. The tumor was well-demarcated from adjacent organs on echography and computed tomographic scan. Transurethral biopsy revealed a bladder leiomyoma. Partial cystectomy was performed. The patient is now apparently free of disease 7 months after the operation.     

Leiomyoma of the bladder: A case report

A case of leiomyoma of the urinary bladder in a 20-year-old man is reported. The patient presented with severe frequency and perineal burning at the end of urination along with microscopic haematuria. Enucleation of the tumour was performed because transurethral biopsy revealed leiomyoma. The prognosis of these tumours is excellent.     

Peritoneal mesothelioma presented with bilateral hydronephrosis: a case report

We report a case of peritoneal mesothelioma presenting with bilateral hydronephrosis, which was difficult to be diagnosed. A 43-year-old woman was admitted to our hospital with acute renal failure. Ultrasonography revealed bilateral hydronephrosis. Retrograde pyelography revealed the stenosis of bilateral lower ureter. Pelvic magnetic resonance imaging demonstrated only a small mass lesion around the bilateral ureter. Other examinations showed no findings of malignancy. Under the diagnosis of retroperitoneal fibrosis, steroid therapy was performed. After 3 months, computed tomography (CT) revealed multiple abdominal masses. Percutaneous needle biopsy of tumor was performed. Pathological diagnosis was peritoneal mesothelioma. Chemotherapy based on the pleural mesothelioma was done but not effective, she died 9 months after the first medical examination.     

Bilateral multiple ureteral polyps causing intermittent hydronephrosis: a case report

We report an unusual case of bilateral ureteral polyps causing intermittent hydronephrosis, which developed extensively in the upper part of ureters. The patient was an 8-year-old male. He had several episodes of gross hematuria with right flank pain. Ultrasonography of the kidney showed mild bilateral hydronephrosis, while this finding was markedly aggravated in association with the onset of pain. Intravenous pyelogram and retrograde pyelogram revealed multiple filling defects in both upper parts of ureters. Since the diseased part of the ureter was wide (about 7 cm in length), a segmental resection of the right ureter with mobilization of the right kidney was performed, followed by end-to-end ureteral anastomosis. The pathological diagnosis was fibroepithelial polyps. Regarding the disease of contralateral ureter, no surgical treatment was performed because he had no clinical symptoms. Six years after the surgery, he again developed gross hematuria with left flank pain. Marked dilatation of the left renal pelvis was shown by ultrasonography, which suggested left intermittent hydronephrosis caused by ureteral polyps. He underwent a partial ureterectomy with mobilization of the left kidney for the left ureteral disease. No recurrence of polyps has been observed in the urinary tract since this surgery.     

Leiomyoma of the urinary bladder treated by transurethral resection: a case report

A 59-year-old woman with complaints of pollakisuria and dysuria, was referred to our hospital. Magnetic resonance imageing (MRI) revealed a tumor, about 59 mm in diameter. Cystoscopy showed a submucosal tumor covered with a normal mucosa. Histological diagnosis was leiomyoma of the urinary bladder by transurethral biopsy. So we performed complete resection of the tumor. To our knowledge, 30 cases of leiomyoma of the urinary bladder by transurethral resection have been reported in the Japanese literature.     

Large pelvic schwannoma causing bilateral hydronephrosis

Schwannoma is a tumor originating from neural sheath schwann cells. We report here a case of benign retroperitoneal schwannoma that caused bilateral ureterohydronephrosis. The retroperitoneal localization in the present case is unusual. The tumor was 21 x 18 x 11 cm in dimension and reached from the prostate to the umbilical level. Even though the patient had bilateral hydronephrosis, the renal function tests results were in the normal range. Complete surgical excision was achieved by anterior laparotomy. Histological and immunohistochemical studies confirmed the diagnosis. At 6 months follow-up there was no evidence of recurrence and renal function test results were normal.     

Sjogren's syndrome with bilateral hydronephrosis caused by pseudolymphoma of bilateral renal pelves: a case report

We report a case of bilateral hydronephrosis caused by pseudolymphoma of bilateral renal pelves. A 52-year-old woman with Sjogren's syndrome and bronchial asthma was found to have bilateral hydronephrosis. Abdominal plain computerized tomography showed an irregular thickening of the bilateral renal pelves with moderate hydronephrosis. The gallium scintigraphy revealed intense tracer uptake in bilateral renal pelves. Open biopsy of the right renal pelvis was performed under the diagnosis of malignant lymphoma. The pathologic diagnosis was pseudolymphoma of the renal pelvis. Steroid therapy dramatically improved pseudolymphoma and hydronephrosis within a month. There were no signs of recurrence.     

Aortic perianeurysmal fibrosis causing bilateral ureteral obstruction: a case report

A 54-year-old male with the chief complaint of bilateral flank pain was admitted to our hospital. Blood chemistry test revealed marked azotemia and retrograde pyelogram showed bilateral hydronephrosis with median shift of narrowed ureters. Abdominal CT scan demonstrated a well-defined dense mass around the aorta implicating bilateral ureters. These findings were interpreted as aortic perianeurysmal fibrosis resulting in bilateral ureteral obstruction. On laparotomy, a large hard mass was found in the lower part of aorta, vena cava, common iliac vessels, inferior mesenteric artery and bilateral ureters. Because of the extension of the mass, ureterolysis and intraperitoneal displacement of ureters wrapped with isolated omentum was performed. Postoperative recovery from azotemia and ureteral obstruction was satisfactory. Biopsy specimen of the mass showed marked fibrosis with non-specific inflammation.     

Leiomyoma of the lung: a case report

An asymptomatic 43-year-old female was admitted to the Hospital because of an abnormal nodule in the left lung field on screening chest X-ray. Chest CT showed a tumor shadow mass (4 x 3 cm) in the left lower lobe. Bronchofiberscopy revealed an endobronchial polypoid mass obstructing the lower lobe bronchus at the orifice of left B10. Lt lower lobectomy was performed. Histopathological examination of the specimen showed the tumor (4.5 x 3.6 x 3.6 cm) developing not only within the tracheal lumen, but also in the lung tissue. Because immunohistochemical staining for desmin and alpha-smooth muscle actin was positive, we diagnosed leiomyoma. As MRI revealed multiple uterine masses after operation, we discussed the diagnostic problems in the relation to metastasizing leiomyoma of the uterus.     

Leiomyoma of the hand: a case report

We report a case of leiomyoma of the finger in the right hand of a 12-year-old boy: a rare site for localization and unusual for age. This is a benign tumor originating from non-striated muscle that is very uncommon in the hand. The uterus is considered the most common location for leiomyoma and when it occurs in the extremities, it is more common in the leg, ankle and foot. It usually occurs in the third and fourth decades of life and it is rarely diagnosed before surgery as the diagnosis can only be confirmed histologically.     

Bilharzial hydronephrosis causing renal failure in a child. A case report

The clinical presentation and management of a young child with renal failure caused by bilharzial obstructive uropathy is discussed. Children from areas in which bilharzia is endemic have a high incidence of urological disease. Ureteric obstruction from inflammatory reaction will respond to medical treatment, whereas true mechanical obstruction from fibrosis will require surgical intervention.     

Giant hydronephrosis causing contralateral ureteric obstruction. A case report

Giant hydronephrosis is a rare condition that occurs predominantly in children. A young girl in whom a massive hydronephrosis compromised contralateral ureteric drainage is reported and the incidence, aetiology and presentation are discussed; guidelines for management are reviewed.     

A case of combination with proliferative cystitis and pelvic lipomatosis causing bilateral hydronephrosis

A 70-year-old man consulted our hospital complaining of gross hematuria and bilateral hydronephrosis. Cystoscopic findings suggested non-papillary sessile tumor at the bladder neck. CT findings revealed bilateral hydronephrosis caused by the stricture of lower ureters. Tumorous structure existed between bladder and prostate. Abundant fatty tissue was observed around bladder and rectum, the shape of the bladder was distorted to inverted tear-drop and the bladder was transferred anteriorly, showing findings of pelvic lipomatosis. Urethrocystography revealed elongation of prostatic urethra and anterior displacement of the bladder. Transurethral tumor resection was performed under spinal anesthesia. Pathological diagnosis was proliferative cystitis and no malignant cells were observed. Transperineal tumor biopsy also revealed no malignant cells. The patient was followed under administration of "Saireitou" (chinese medicine) and cetirizine hydrochloride, followed by antibiotics and anti-inflammatory enzyme preparations.     

Leiomyoma of the scrotum: a case report]

A case of intrascrotal leiomyoma is reported. A 62-year-old male was admitted to our hospital with the chief complaint of a painless intrascrotal mass, which had been gradually increasing in size during the past 25 years. Physical examination revealed impervious to light and elastic firm mass of 5 cm in diameter in the left scrotum. Although the serum level of some tumor markers such as alpha fetoprotein and human chorionic gonadotropin-beta were normal, since the border on the left testis was unclear on the ultrasonogram of the scrotum, a testicular tumor was suspected, and radical orchiectomy was performed. The tumor was 6 x 4 x 4 cm, 55 g, and well-defined with testis, epididymis and tunica dartos. It was histopathologically diagnosed as leiomyoma arising from the tunica vaginalis. The post operative course has been uneventful for 9 months after the surgery, and no recurrence has been recognized. An intrascrotal tumor is relatively rare, and is generally defined as one arising between tunica dartos and tunica vaginalis testis, which is independent of testis, epididymis, and funiculus spermaticus. This is the 25th case of intrascrotal leiomyoma reported in the literature in Japan.     

Leiomyoma of duodenum: report of a case

A case of a large leiomyoma of the duodenum and how it presented is reported. Difficulties in making a preoperative diagnosis and the surgical approaches to its treatment are discussed.     

Bilateral hydroureter and hydronephrosis causing renal failure due to a procidentia uteri: a case report

We report a case of complete uterine prolapse that resulted in bilateral hydroureter, hydronephrosis, and renal dysfunction. The nonoperative reduction of the prolapse with a vaginal pessary reversed the obstructive uropathy and ameliorated renal function. The lower urinary tract should be imaged in patients with complete uterine prolapse. If present, obstructive uropathy should be relieved by the reduction of the prolapse before irreversible renal damage occurs.     

Leiomyoma of the bladder. Report of a case

Benign bladder tumors of mesenchymal origin have a very low appearance incidence, being the most frequent the leiomyoma. We report new case, making a discussion about the complementary tests needed for the diagnose.
