PURPOSE: Patients requiring urethral reconstruction due to failed hypospadias repairs present a considerable technical challenge. Herein we report the experience of redo urethroplasties for complicated recurrent hypospadias. MATERIALS AND METHODS: From 1987 to 1997, we performed redo urethroplasty in 11 cases with complicated recurrent hypospadias. Types of recurrent hypospadias were coronal (1 case), distal shaft (4 cases), mid-shaft (1 case), and penoscrotal (5 cases) hypospadias. The interval between the last operation and redo operation was distributed from 8 months to 5 years. We analysed preoperative status, operative methods and their complications retrospectively. RESULTS: We performed urethroplasties using scrotal skin flap or buccal mucosal graft in only 2 cases. In spite of a paucity of usable penile skin, we performed urethroplasties with maximal use of remaining penile skin. Mathieu method was used in one case with coronal type. Mustarde operation was used in 4 cases with distal shaft hypospadias. And in 5 cases with penoscrotal type, we used Thiersch-Duplay method. Six of 11 patients had complications such as urethrocutaneous fistulas (4 cases) or recurrent hypospadias (2 cases) which were managed successfully later. CONCLUSIONS: Urethroplasty using penile skin maximally such as Mathieu, Mustarde, or Thiersch-Duplay methods appears to achieve success in patient with recurrent hypospadias subsequent to previous failed repairs.

A rare case of intramedullary Cysticercosis, at the thoracic cord is introduced which was misdiagnosed as intramedullary tumor and was confirmed after operation. After myelogram developed progressive paraplegia, which was not improved after operation. The myelographic finding of intramedullary Cysticercosis can't differenciate from intramedullary tumor and we have to consider this condition making diagnosis of intramedullary tumor.

Tethered cord syndrome is one of the spinal dysraphism with low-lying conus medullaris frequently associated with spinal lipoma, diastematomyelia and thick filum. The clinical manifestation is variable from no overt symptoms for a long time to back pain, scoliosis, progressive neurological deficit of legs and incontinence. Therefore the diagnosis requires a strong clinical suspicion and aggressive investigation. We experienced a case of 1 day-old male infant who was presented with small soft mass on sacral area. Spinal ultrasonography and spine MRI revealed tethered cord associated with intradural lipoma. We reported a case of tethered cord syndrome with brief review of literatures.

Renal cell carcinoma takes up 85 per cent of primary malignant renal tumors. It frequently metastasizes to the adrenal gland, lung, bone, liver and nephrectomy site but rarely to the head and neck area. When metastasizes to head and neck area, it involves the gingiva, tongue, palate, parotid gland, uvula, mandible, and lip. When tumors are found in the salivary gland consisting of clear cells, it is impartant to carry out differential diagnosis of various primary tumors with clear cell and metastatic renal cell carcinoma. Patients' medical history, review of system, and pathologic findings would be helpful factors in the differential diagnosis. In this paper, we report on a case of renal cell carcinoma which had metastasized to the psubmandibular gland after a radical nephrectomy.

Plate fixation is being regarded as one of the reliahle fixation method in the management of tibial fractures. But this technique may leave many complications including infection. However, delayed local infection which developed several weeks after open reduction on the tibia has been rarely described as a complication in the literatures. The purpose of this study is to evaluate the contributing factors to the delayed locaI infection in tibial fracture treated with plate fixation. Authors reviewed and analyzed the 60 cases of tihial fracture that were treated with plate and screws from 1989 to 1996. Analyses dealt with fracture classification, laboratory and radiographic findings and the site of plate application. We defined a delayed local infection as a condition in which patient has infection signs on Jaboratory and physical examination at or over 8 week post-operation without any evidence of osteomyelitis on plain radiographs. We found 7 cases of delayed local infection out of 60 tibial fractures from 8 to 21 weeks postoperatively with an average of 14.1 weeks. All the 7 cases that had been treated with plate on medial aspect of tibia were treated by administration of antibiotics without surgery such as debridement or removal of hardwares. Authors concluded that the medial plating was the most important factor of the development of delayed local infection(Z=1.78).

Torsades de pointes is a polymorphic ventricular tachycardia associated with prolonged QT interval and increased U wave amplitude. It has been found to be induced by various drugs, electrolyte imbalances, and so on, but the mechanism of torsades de pointes has not been completely documented. Two hypotheses, early afterdepolarization and dispersion of repolarization have been known to be the possible mechanism. Terfenadine and astemizole are the antihistamines, known to be one of the etiologic agents of torsades de pointes, and factors associated with increased risk are significant liver disease, drug overdose, and concomitant administration of imidazole and macrolide antimicrobial drugs. There has been only one case reported that torsades de pointes had been induced by first-generation antihistamine, piprinhydrinate. We experienced a case of 43 year old male patient with torsades de pointes induced by first-generation antihistamine, hydroxyzine and treated successfully with drug cessation, MgSO

OBJECTIVE: On the basis of preoperative computed tomography (CT) scans, we studied the change of the size of anterior primary division (APD) of the L5 spinal root in the presence of foraminal/extraforaminal entrapment of the L5 spinal root. METHODS: Two independent radiologists retrospectively reviewed the preoperative CT scans of 27 patients treated surgically and compared the sizes of the APDs on bilateral L5 spinal roots. If one side APD size was larger than the other side APD size, it was described as left or right "dominancy" and regarded this as "consensus (C)" in case that there was a consensus between the larger APD and the location of sciatica, and regarded as "non-consensus (NC)" in case that there was not a consensus. Oswestry Disability Index (ODI) scores were used for preoperative and postoperative evaluation. RESULTS: On CT scans, twenty-one (77%) of 27 patients were the consensus group (APD swelling) and 6 (22%) were a non-consensus group (APD no swelling). In 9 patients with acute foraminal disc herniations, asymmetric enlargement of the APD on L5 spinal root was detected in all cases (100%) and detected in 11 (64%) of 17 patients with stenosis. Preoperative ODI score was 75-93 (mean 83) and postoperative ODI scores were improved to 13-36 (mean 21). The mean follow-up period was 6 months (range, 3-11 months). CONCLUSION: An asymmetric enlargement of the APD on L5 spinal root on CT scans is meaningfully associated with a foraminal or extraforaminal entrapment of the L5 spinal root on the lumbosacral junction.
