Bladder stone in a woman after cesarean section: a case report.

Urinary bladder calculi are rarely seen in women and any history of previous pelvic surgery must, therefore, raise suspicion of an iatrogenic etiology. According to the literature, fewer than 2% of all bladder calculi occur in female subjects and, thus, their presence should provoke careful assessment of the etiology. There have been a number of reports on bladder calculi in women with a history of gynecologic procedures. We report a case of bladder calculus after cesarean section that was treated successfully by open surgery.

Double J stent forgotten for 7 years: a case report.

Ureteral stents are an integral part of urologic practices. Nonetheless, stents that migrate, fragment, or are forgotten pose management and legal dilemmas. We report the case of a "forgotten" stent, which migrated upward into the right renal pelvis, concomitant with a ureteral stone. The "forgotten" stent was placed 7 years previously during right ureteral stone treatment. The patient finally underwent nephroscopic stent retrieval and ureteroscopic ureteral stone removal. The final plain X-ray demonstrated no stone fragment or residual double J stent fragment. The patient withstood the procedure well and was free of symptoms thereafter.

Kallmann syndrome--a case report.

Kallmann syndrome is a very rare hereditary disease. It is characterized by hypogonadotropic hypogonadism in association with anosmia ot hyposmia, both of which occur as a result of the failure of neuronal migration of the luteinizing hormone releasing hormone (LHRH)--secreting neurons and the neurons of the vemeronasal nerve. It can be autosomal dominant, autosomal recessive, or X-linked mode of inheritance. We report a case of Kallmann syndrome that presented with delay puberty, color blindness, gynecomastia, and absence of smell. Plasma levels of LH, FSH and testosterone were very low. The patient's adrenal and thyroid hormone levels were normal. Chromosome analysis showed 46, XY karyotype without deletion in KAL gene (Xp22.3) from FISH. After 9 months of treatment by HCG and HMG, the amount of pubic hair and the volume of bilateral testes, as well as the level of testosterone had increased. Most importantly, motile sperm count be found in semen.

Adrenal tumors: 10-year experience at Kaohsiung Medical University Hospital and literature review.

We report our 10-year experience of managing adrenal tumors at Kaohsiung Medical University Hospital (KMUH) between January 1992 and January 2002. In total, 53 patients with adrenal tumors were analyzed, including 19 men (mean age +/- standard deviation, SD, 41.8 +/- 12.9 yr; range, 24-66 yr) and 34 women (mean age +/- SD, 42.3 +/- 12.4 yr; range, 19-74 yr), with an overall mean age +/- SD of 42.6 +/- 12.5 years. All 53 adrenal tumors were confirmed by surgery and pathology. In our series, 41 (77.4%) tumors were functional, of which 39 (95%) were benign; 12 (22.6%) tumors were nonfunctional, of which two (16.7%) were malignant. Overall, women were more common than men in our series, especially in Cushing's syndrome and primary aldosteronism (female:male ratio, 4 and 1.9, respectively). Of the 41 functional adrenal tumors, 20 were primary aldosteronism, 10 were Cushing's syndrome, 10 were pheochromocytoma, and one was an androgen-producing tumor. Of the 12 nonfunctional adrenal tumors, all of which presented as adrenal incidentalomas, four were cortical adenoma, three were myelolipoma, two were ganglioneuroma, one was an adrenal cyst, one was an adrenocortical carcinoma, and one was a metastatic carcinoma. Overall, 48 patients underwent adrenalectomy, three underwent partial adrenalectomy for small and well-circumscribed tumors, and two were explored. The diagnosis and management of adrenal tumors is discussed and the literature reviewed.

Hand-assisted laparoscopic live donor nephrectomy: a case report.

Live donor renal transplantation offers significant advantages over cadaveric renal transplantation. It yields significantly better patient and graft survival on both short-term and long-term follow-up. Laparoscopic donor nephrectomy minimizes the morbidities associated with the surgical procedure and allows a speedy return to normal daily activities. The operation also provides an atraumatic kidney subjected to minimal warm ischemia time and with adequate length of artery and vein, resulting in immediate functioning of the kidney after transplantation with a low rate of ureteral complications. A 37-year-old man was referred as a kidney donor for his brother. Both donor and recipient were hepatitis-B surface antigen carriers. Cross-matching and human leukocyte antigen test showed good compatibility. Left donor nephrectomy was performed successfully by hand-assisted laparoscopy. The warm ischemic time was 4.5 minutes and the graft kidney functioned immediately after transplantation. The donor was discharged from the hospital on postoperative Day 3 with good recovery.

Matrix stone.

Matrix stone is a rare form of renal calculi, and it is often difficult to make an exact preoperative diagnosis. To our knowledge, we reported the first case of matrix stones which received magnetic resonance imaging (MRI) for image study. They showed hypointense signal in T1-weighted images and slight hyperintense signal in T2-weighted images. No obvious contrast enhancement was found after gadolinium administration in T1-weighted images. Besides, postoperative study of computerized tomography (CT) for matrix stones also showed the characteristic of soft tissue densities by measuring the Hounsfield units. We think our experiences may provide some help for the diagnosis of matrix stones when someone encounters the same situation and may prevent overtreatment due to misdiagnosis as malignancy.
