[A Case of Upper Urinary Tract Stone in an Infant].

A 238-day-old female infant (122 days of age corrected for prematurity, weight 4,847 g) presented with macrohematuria. She was born at 23 weeks and3 days of pregnancy. Her birth weight was 492 g.

[A Case of Testicular Tumor with Multiple Metastasis Leading to Complete Response after Treatment Interruption].

A 39-year-old man experiencing cranial nerve symptoms was referred to our neurosurgery department after a brain tumor was detected on computed tomography (CT) scans at a local hospital. Due to convulsive symptoms, the patient was admitted to our hospital for detailed examination. The patient was diagnosed with right testicular tumor, multiple brain metastases, multiple lung metastases and right kidney metastases, and was transferred to our urology department.

Familial testicular germ cell tumors in two brothers.

Introduction: Two percent of testicular germ cell tumors occur in family clusters. Here, we report metachronous testicular germ cell tumors in two brothers.

Case Presentation: An elder brother was diagnosed at the age of 30 years old and the pathological diagnosis was mixed testicular germ cell tumor.

Newly Identified t(2;17)(p15;q24.2) Chromosomal Translocation Is Associated with Dysgenetic Gonads and Multiple Somatic Anomalies.

Campomelic dysplasia (CD) is a skeletal dysplasia characterized by shortened and bowed long bones, airway instability, the potential for disorders of sexual differentiation (DSD), and Pierre Robin Sequence (PRS) with cleft palate, midface hypoplasia and laryngotrachemomalacia. CD is caused by alterations in the Sex-determining region of the Y chromosome (SRY)-related-box 9 (SOX9), which has important roles in tissue and sexual differentiation. The SOX9 gene and the enhancer regions of SOX9 are located at chromosome 17q24.

Evaluating estimated glomerular filtration rates of creatinine and cystatin C for male patients with chronic spinal cord injury.

Study Design: Retrospective study OBJECTIVES: To compare the accuracy of estimated serum creatinine (Cre)-based glomerular filtration rates (eGFRcre) and serum cystatin C (CysC)-based eGFR (eGFRcys) for determining renal function in patients with spinal cord injury (SCI).

Setting: Department of Urology, Tohoku Rosai Hospital, Japan METHODS: Male patients with SCI for longer than 5 years after injury were eligible for inclusion in this study. eGFRcre and eGFRcys were calculated using the following formulas: eGFRcre = 194 × Cre × age; eGFRcys = (104 × CysC × 0.

Surgical indication and outcome in patients with postoperative retethered cord syndrome.

Object: After untethering of spinal dysraphism, some patients present with neurological deterioration, defined as retethered cord syndrome. It is known that surgical untethering is an option for improving the symptoms of retethered cord syndrome. Previous reports have shown that postoperative improvement in retethered cord syndrome was noted in the majority of patients presenting with pain, and in more patients with motor weakness than in those with urological symptoms.

A case of large bladder hemangioma successfully treated with endoscopic yttrium aluminium garnet laser irradiation.

Bladder hemangioma is a rare benign tumor. While partial cystectomy remains an effective treatment option for large bladder hemangioma, the combined method of neodymium:yttrium aluminium garnet and holmium:yttrium aluminium garnet laser irradiation is an effective and less invasive treatment option. We report a case of large bladder hemangioma in an otherwise healthy 4-year-old boy, successfully treated with serial endoscopic yttrium aluminium garnet laser irradiation.

Potentiation of potassium currents by beta-adrenoceptor agonists in human urinary bladder smooth muscle cells: a possible electrical mechanism of relaxation.

We examined the effects of beta-adrenoceptor agonists on the membrane currents of smooth muscle cells from the human urinary bladder using a whole-cell patch clamp to investigate the involvement of Ca(2+)-activated K(+) (K(Ca)) channels in relaxation by beta-adrenergic agonists. With 0.05 mmol/l EGTA in the patch pipette, depolarizing pulses evoked outward rectifying currents.

[A case of schwannoma in psoas muscle].

We report a case of schwannoma in psoas muscle, difficult to make a preoperative differential diagnosis from multilocular renal cyst in a 44-year-old woman. She complained of epigastric discomfort, and abdominal computerized tomography revealed a left multi-cystic renal tumor. Drip infusion pyelography showed the tumor displacing the left kidney superiorly, and pushing the left ureter medially.

[Bilateral partial nephrectomy in a case of bilateral synchronous renal cell carcinoma].

We report a case of bilateral synchronous renal cell carcinoma in a 66-year-old-man, who underwent bilateral partial nephrectomy. He visited our hospital, complaining of left flank pain. Drip infusion pyelography showed a left ureteral stone and left hydroureteronephrosis.

Clinical features of prostate cancer patients younger than 50 years: report of seven cases.

Background: The incidence of prostate cancer increases with age and latent cancer is common in older men. But clinical prostate cancer is rare in men aged < 50 years.

Methods: Between 1988 and 2000, we studied seven cases of prostate cancer in men aged under 50 years.
