We report a case of epidermolysis bullosa simplex, Dowling-Meara type (EBS-DM), which was associated with congenital pyloric atresia (PA) and various urologic abnormalities, a diagnosis confirmed by immunofluorescence mapping and electron microscopic findings. Immunofluorescent mapping showed the serum from a patient with bullous pemphigoid faintly binding to the floor of the blister, and monoclonal antibodies against type IV and VII collagens were also stained on the floor of the blister. Electron microscopy showed epidermolytic cleavage and prominent clumping of tonofilaments in the basal and suprabasal keratinocytes. An abdominal radiograph and barium swallow showed a complete obstruction at the pyloric channel level. The widespread bullae healed without any scar formation and the bullae formation was localized on the extremities after 3 months of age without any specific treatment. Multiple urologic abnormalities such as bilateral hydronephrosis, hydroureter and a distended bladder with trabeculation were observed at 12 months of age. Currently, with the patient at 4 years of age, bullae still appear on the hands and feet and nail shedding can be observed. The patient's father, a paternal uncle and a paternal aunt had had similar bullous eruptions in infancy, all of which had improved spontaneously by the age of one.

PURPOSE: We report our experience to date with 171 patients who underwent laparoendoscopic single-site surgery for diverse urologic diseases in a single institution. MATERIALS AND METHODS: Between December 2008 and August 2010, we performed 171 consecutive laparoendoscopic single-site surgeries. These included simple nephrectomy (n=18; robotic surgeries, n=1), radical nephrectomy (n=26; robotic surgeries, n=2), partial nephrectomy (n=59; robotic surgeries, n=56), nephroureterectomy (n=20; robotic surgeries, n=12), pyeloplasty (n=4), renal cyst decortications (n=22), adrenalectomy (n=4; robotic surgeries, n=2), ureterolithotomy (n=10), partial cystectomy (n=3), ureterectomy (n=1), urachal mass excision (n=1), orchiectomy (n=1), seminal vesiculectomy (n=1), and retroperitoneal mass excision (n=1). All procedures were performed by use of a homemade single-port device with a wound retractor and surgical gloves. A prospective study was performed to evaluate outcomes in 171 cases. RESULTS: Of the 171 patients, 98 underwent conventional laparoendoscopic single-site surgery and 73 underwent robotic laparoendoscopic single-site surgery. Mean patient age was 53 years, mean operative time was 190.8 minutes, and mean estimated blood loss was 204 ml. Intraoperative complications occurred in seven cases (4.1%), and postoperative complications in nine cases (5.3%). There were no complications classified as Grade IIIb or higher (Clavien-Dindo classification for surgical complications). Conversion to mini-incision open surgery occurred in seven (4.1%) cases. Regarding oncologic outcomes, no cancer-related events occurred during follow-up other than one aggressive progression of Ewing sarcoma. CONCLUSIONS: Laparoendoscopic single-site surgery is technically feasible and safe for various urologic diseases; however, surgical experience and long-term follow-up are needed to test the superiority of laparoendoscopic single-site surgery.

PURPOSE: A retrospective review of the medical records of 168 patients who were evaluated for renal transplantation was undertaken to determine whether a voiding cystourethrography (VCUG) influenced the surgi cal care of the recipient. MATERIALS AND METHODS: Between June 1989 to May 1998, 168 patients received a transplantation at our center. These patients proceeded to transplantation, with all of them receiving a VCUG as part of their evaluation. We compared incidence of postoperative complications between normal VCUG group and abnormal group during follow up period (mean 31. 6 months). RESULTS: An urologic abnormality was identified by VCUG in 15 (8.9%) of 168 patients and all of them were vesicoureteral reflux (VUR). In 15 patients with VUR, grade of VUR were grade I in 2, grade II in 10, grade III in 2 and grade IV in 1. None of them with VUR required surgical intervention and had postoperative complications related to VUR. CONCLUSIONS: The VCUG is not essential for the preparation of potential recipients for renal transplantation and should be utilized selectively in individuals with a history of urologic disease or when urinary tract abnormalities are identified by physical examination or an abnormal urine analysis.

OBJECTIVETo evaluate the urodynamic risk factors of upper urinary tract dilatation (UUTD) secondary to spinal cord injury (SCI).
METHODSNinety-six SCI patients of Tangshan earthquake were divided into 2 groups by ultrasonography: 16 SCI patients (group A) with UUTD and 80 SCI patients (group B) without UUTD received urodynamic test. Responses were evaluated using single and multiple analysis after examination.
RESULTSThe incidence of male was significantly higher than that of female. Residual urine volume, maximum cystometric capacity, detrusor leak point pressure and the incidence of bladder low compliance in group A were significantly higher than those in group B. There were no significant differences in age, the incidence of detrusor hyperreflexia, relative safe bladder capacity, the incidence of detrusor-sphincter dyssynergia, maximum flow rate and maximum urethral closure pressure between 2 groups. Bladder low compliance was cardinal risk factors according to Logistic regression analysis.
CONCLUSIONAn early urodynamic examination and treatment for SCI patients are important to prevent from bladder low compliance and upper urinary tract damage.

7.Clinical Observation on 101 Cases of Epididymitis.
Korean Journal of Urology 1979;20(2):191-198
Epididymitis is the most common of all the intrascrotal inflammations. It is mainly a disease of adults, and only rarely affects the prepubertal child. 107 cases of epididymitis seen during the period from January 1975 to June 1978 were studied. Clinically and the following results were obtained. 1. Incidence of epididymitis is 14.72% of all urological diseases of all in patients. 2. Lateralization shows 35.5% in the Right, 43% in the Left and 21.5% in the both. 3. The site of invasions is the most popular in the tail(50.7%). 4. The etiologic factors are observed the infection(non-specific 37.7%. Tuberculosis 20.8%) trauma (post-surgical 13.8%, injury 10.8%), and idiopathic(16.9%). 5. The surgical procedure followed by epididymitis is the most common in the hydrocelectomy (22.2%), next in the vasectomy(16.7%). Of presenting symptom, painful epididymal swelling is observed in 37.1%, painless epididymal swelling 16.7 %, inguinal dragging pain 258 and fever 6.8%. 6. The operation indicated in the epididymal mass(35.5%), scrotal fistular and abscess formation(22.6%), severe scrotal pain(19.4%), recurrent infection(16.1%) and epididymorchitis(6.4%). 7. In 76 cases of them conservative management are performed and in 31 cases of them surgical management are performed. The surhical procedure is the most common in partial epididymectomy(19.4%). 8. The epididymal open biopsy for differential diagnosis on the scrotal swelling are performed in 26 cases of the outpatients. The tuberculous epididymitis is the most common(26.9%), 9. The postoperative complication is noted the further increased epididymal induration in 16.1%, oligospermia in 9.7%, persistent inguinal dragging pain in 6.6% and wound infection in 3.2%. 10. The duration of hospitalization are average 15 days but on the surgical cases, within 2-3weeks are noted in 38.7%. On the conservative management cases, more than 4 weeks are noted in 28.9%.

Chinese Journal of Surgery 2002;40(6):441-444
OBJECTIVESTo improve the diagnosis of patients with neurogenic lower urinary tract dysfunction and to provide a basis for proper selection of rehabilitation methods.
METHODSThe urodynamics was tested with Assend Urodynamic Instrument in 220 patients with spinal cord injury. Of these patients, 100 received regular cystometrograrhy (CMG) and urethal pressure profile (UPP) test, and the remaining patients were measured by bladder/ external sphincter pressure profile. The detrusor pressure, maximum detrusor voiding pressure, and maximum urethral pressure were recorded. The date from the tests were processed with SPSS 8.0 (independent samples T test).
RESULTSThe maximum urethal pressure (83 +/- 39) cm H(2)O (1 cm H(2)O = 0.098 kPa) and maximum voiding detrusor pressure (12 +/- 10) cm H(2)O were lower in coda-equina group than in other groups (t = 2.096,P < 0.05). The group with different spinal cord injury had almost an equal ratio of low bladder compliance (51.2%, 52.4% and 50% separately). Statistical differences were found between complete injury and incomplete injury in each group(t = 1.023, P > 0.05). In bladder/external sphincter cystometry, urethral pressure profile could be classified into four types.
CONCLUSIONSThe maximum urethral pressure and maximum pressure of detrusor contractile were lower in the cauda-equina injury group than in other groups. The cauda-equina injury group showed a lower incidence of detrusor sphincter because most of these patients were incompletely injured. The features of urethral pressure profile in bladder/external sphincter cystometry resulted from the abnormal contraction of external sphincter and periurethral striated muscles.

Journal of Korean Medical Science 2005;20(1):75-78
The pre-transplantation goal of the urologist is the optimization of urinary tract condition. Therefore, urologic surgery may be needed before or after renal transplantation. We analyzed the results of urologic surgery performed because of de novo urologic diseases. Between January 1986 and January 2001, 281 patients underwent renal transplantation, and 23 urologic surgical procedures were performed on 21 transplant recipients before or after renal transplantation because of de novo urologic diseases. By review the major reasons for urologic surgery in recipients were polycystic kidney diseases, vesicoureteral reflux, and dysfunctional voiding disorders. Nineteen surgical corrective procedures were done average 2.9 months before transplantation. The mortality rate was 10.5%. Four patients underwent urologic surgery at an average 57.5 months after transplantation. We highlight the fact that patients with uremia are vulnerable to surgical complications, and conclude that more intensive longterm urologic follow-ups should be conducted on recipients.

BACKGROUNDThe research of cancer in patients on hemodialysis (HD) in China has not been reported. The aim of this study was to investigate the clinical and histological features and outcomes of cancer in Chinese HD patients.
METHODSThe study subjects were 49 cancer patients (1.4%) out of 3448 end stage renal disease (ESRD) patients maintained on HD at China-Japan Friendship Hospital from October 1997 to July 2011.
RESULTSUrinary tract cancer (74%) was the most common followed by gastrointestinal tract cancer (12%), breast cancer (6%), lung cancer (4%), thyroid cancer (2%), and hematologic cancer (2%). Thirty-three patients (67%) had urinary tract transitional cell carcinoma (TCC) and 29 of them had aristolochic acid nephropathy (AAN) as underlying disease. Death occurred in eight patients out of 49, and the survival rate of HD patients with cancer was similar to those without cancer (P = 0.120).
CONCLUSIONThe urinary tract TCC is the most common cancer in HD patients with AAN in one of the centers of northern China.
