PURPOSE: Laparoscopic nephroureterectomy (LNUx) has recently been done to treat patients with upper tract transitional cell carcinoma. We retrospectively evaluated the efficacy and safety of LNUx in comparison with open nephroureterectomy (ONUx). MATERIALS AND METHODS: Between May 2001 and March 2006, a total of 51 patients underwent radical nephroureterectomy for upper tract transitional cell carcinoma, including 22 LNUx and 29 ONUx. LNUx was performed transperitoneally and the ureteral end with a bladder cuff was transected through a 5-7cm modified Gibson incision. All the specimens were extracted intact. The patients' characteristics and the perioperative and followup data were analyzed retrospectively. RESULTS: LNUx was successfully performed in all the patients without open conversion. The analgesic requirement was lower, and the average time to oral intake and the length of hospitalization were shorter for LNUx than for ONUx. The average operative time, estimated blood loss and complications were not statistically different between the LNUx and ONUx. The mean follow-up periods of the LNUx and ONUx were 13.7 and 30.0 months, respectively. Both groups were similar in regard to bladder recurrence, local recurrence and distant metastasis. There was no sign of the trocar site or peritoneal seeding after LNUx. CONCLUSIONS: Our results suggest that LNUx is an acceptable alternative to ONUx for treating upper urinary tract transitional cell carcinoma. However, a longer follow-up period and comparative studies to the standard open techniques will be required.

Sebaceous hyperplasia can occur on the face during middle age, particularly in men. The risk of sebaceous hyperplasia is significantly increased in adult transplant patients, particularly males, following renal transplantation, and this is related to therapy with cyclosporine. We report on 2 cases of sebaceous hyperplasia in renal transplant patients who were treated with cyclosporine. The condition was improved, without scarring, by treatment with carbon dioxide laser or cryotherapy.

BACKGROUND: Vibrio (V.) vulnificus is a pathogenic marine bacterium that can cause rapid progression of a life-threatening infection. Although V. vulnificus sepsis is well-known to Koreans and was designated as a legal communicable disease in August 2000, many people still become infected each year. OBJECTIVE: The purpose of this study was to investigate the clinical features of V. vulnificus sepsis, in order to offer basic data for the treatment and prevention of this disease. METHODS: We reviewed the available data of 141 patients with V. vulnificus sepsis, which were obtained from 105 patients admitted to hospital and 36 case reports published in the Korean medical journals between 1982 and 2004. RESULTS: Eighty-five percent of patients were 40 to 60 years old. Men were affected 10.5 times more often than women. Patients with underlying chronic diseases (94%) such as alcohol abuse and liver diseases displayed primary sepsis starting with fever, chills, and/or diarrhea, often within 2.3 days of consumption of various kinds of raw seafood. Skin lesions appeared initially as a painful, localized swelling like a bee-sting, followed by edema, blisters, purpura, necrosis and, less commonly, maculopatch, cyanosis, papules, wheals, pustules or erythema multiforme-like lesions. The cutaneous lesions that were present in 91.5% of patients on admission, appeared on the lower extremities in 88.9% of the cases. Of the 141 patients, 88 patients (62.4%) died. The mortality rate increased as initiation of treatment was delayed. Laboratory findings revealed thrombocytopenia and elevated levels of liver enzymes in many tested cases. V. vulnificus was cultivated more easily from the skin lesion (95%) than blood (69%). There were significant differences in systolic blood pressure, leukocyte count and creatinine between survivors and nonsurvivors (p<0.05). V. vulnificus was highly susceptible to several kinds of antibiotics such as ampicillin, ciprofloxacin, and 3rd generation cephalosporins. Mortality rate increased as the delay from the onset of illness to the initiation of treatment was prolonged. CONCLUSION: Clinicians should promptly initiate appropriate therapy for patients with underlying chronic disease if they exhibit unexplained fever and diarrhea after ingesting raw seafood.

PURPOSE: The purpose of this study was to examine whether urethroplasty with a turnover flap, as an alternative method of distal hypospadias repair in adolescents, improves the outcome of surgery. MATERIALS AND METHODS: Between January 2004 and December 2013, a total of 38 adolescents (aged 11-17 years) underwent distal hypospadias repair with either the tubularized incised plate (TIP) procedure (n=25) or the turnover flap procedure (n=13). The turnover flap procedure was performed with a proximal, ventral penile flap that was turned over to cover the urethral plate. Patient demographics, perioperative outcomes, complications, and postoperative uroflowmetry in each surgical group were analyzed retrospectively. RESULTS: The patient demographics were similar in the two groups. There were no significant differences in perioperative outcomes between the groups, including mean operative time, duration of hospital stay, and urethral catheterization. The number of patients with at least one complication, including wound dehiscence, urethrocutaneous fistula, meatal stenosis, and urethral stricture, was lower in the turnover flap group (1/13, 7.7%) than in the TIP group (11/25, 44%, p=0.030). The incidence of meatal stenosis was lower in the turnover flap group (0/12, 0%) than in the TIP group (6/25, 24%). In postoperative uroflowmetry, the plateau-shaped curve rate was lower in the turnover flap group (1/12, 8.3%) than in the TIP group (5/19, 26.3%); the peak flow was higher (p=0.030). CONCLUSIONS: The turnover flap procedure is clinically useful for repairing adolescent distal hypospadias because it offers lower complication rates and better functional outcomes than TIP.

A gastrointestinal stromal tumor is the most common mesenchymal tumor of the gastrointestinal tract, and is diagnosed on the basis of the combined expression of CD34 and CD117 (C-kit protein). An extragastrointestinal stromal tumor of the urinary bladder is a very rare neoplasm. In this report, we describe a case of an extragastrointestinal stromal tumor originating from the inner surface of the urinary bladder. A 46-year-old man presented with an incident bladder mass, and he was diagnosed with an extragastrointestinal stromal tumor after transurethral resection of the bladder tumor. A tumor on the inner urinary bladder wall is an unusual presentation of an extragastrointestinal stromal tumor. The patient is doing well with no recurrence at 18 months after surgery.

Reed's syndrome is a rare, autosomal dominant disease with incomplete penetrance that is characterized by uterine and cutaneous leiomyomas. We report a case of Reed's syndrome in a 50-year-old woman. The patient underwent removal of the uterine leiomyoma at the age of 36. Following this the patient noticed development of multiple, cutaneous nodules on both arms at the age of 45. These nodules progressively increased in both number and size, while appearing in other sites. The histopathologic finding of an isolated, single skin lesion showed typical leiomyoma arising from arrector pilorum muscle. Familial history revealed that her father had been affected with similar cutaneous lesions.

Duplication of the vas deferens is a very rare congenital anomaly in which two vasa deferentia coexist within the spermatic cord. Duplication of the vas deferens can be found during herniorrhaphy, vasectomy, and varicocelectomy performed on the spermatic cord or around the spermatic cord. However, it is estimated that the incidence of duplication of the vas deferens is under-reported and under-recognized. Unless anomalies of the vas deferens such as duplication of the vas deferens are recognized by surgeons, it will be difficult to reduce vas deferens injuries and achieve a satisfactory surgical outcome. In addition, care should be taken in cases of duplication of the vas deferens because it can be complicated by non-testicular genitourinary anomalies. We report a case of duplication of the vas deferens discovered during routine varicocelectomy.

OBJECTIVE: Few data exist regarding adjuvant hysterectomy (AH) in locally advanced cervical cancer (LACC) patients treated with chemoradiotherapy. We investigated the effect of AH on prognosis in LACC patients, through meta-analysis. METHODS: EMBASE and MEDLINE databases and the Cochrane Library were searched for published studies comparing LACC patients who received AH after chemoradiotherapy with those who did not, through April 2016. Endpoints were mortality and recurrence rates. For pooled estimates of the effect of AH on mortality/recurrence, random- or fixed-effects meta-analytical models were used. RESULTS: Two randomized trials and six observational studies (AH following chemoradiotherapy, 630 patients; chemoradiotherapy, 585 patients) met our search criteria. Fixed-effects model-based meta-analysis indicated no significant difference in mortality between the groups (odds ratio [OR]=1.01; 95% confidence interval [CI]=0.58–1.78; p=0.968) with low cross-study heterogeneity (p=0.73 and I2=0.0). This pattern was observed in subgroup analysis for study design, radiation type, response after chemoradiotherapy, and hysterectomy type. The pooled OR for AH and recurrence was 0.59 (95% CI=0.44–0.79; p < 0.05) with low cross-study heterogeneity (p=0.29 and I2=17.8), favoring the AH group. However, this pattern was not observed in the subgroup analysis for the randomized trials. There was no evidence of publication bias. CONCLUSION: In this meta-analysis, AH following chemoradiotherapy did not improve survival in patients with LACC, although it seemed to reduce the risk of recurrence. Concerning the significant morbidity of AH after chemoradiotherapy, routine use of AH should be avoided.

Kleefstra syndrome is a rare genetic disease characterized by mental retardation, hypotonia, and a characteristic facial appearance. Furthermore, in some cases, Kleefstra syndrome is associated with various anorectal and genitourinary complications, including imperforated anus, vesicoureteral reflux, hydronephrosis, and chronic kidney disease. Herein, we present a case of Kleefstra syndrome with recurrent urinary tract infections associated with vesicoureteral reflux and rectourethral fistula, which was treated by a multidisciplinary approach.
