Change in Penile Length in Children: Preliminary Study

PURPOSE: Studies of penile length in children have been rarely conducted. In Korea, great improvements in height and weight have been observed because of economic development over the past 25 years. We investigated the current status of penile length in Korean children and compared the results with those of a previous Korean study conducted in 1987. MATERIALS AND METHODS: The subjects in this study were 233 boys aged 1 to 158 months, each of whom had been brought to outpatient clinics between April and October 2011. Penile length was measured according to the stretched penile length (SPL) technique; testicular size was measured (in ml) by using orchidometry. A comparison of penile lengths between the current study and the 1987 study was made by using Student's t-test. RESULTS: SPL increased significantly by 0.7 to 1.1 cm in most age groups (p<0.05). Current anthropometric measures of Korean children such as height, body weight, and testicular size have increased compared with those from 1987. CONCLUSIONS: Penile length has increased significantly over the last quarter century. Therefore, it is suggested that novel reference values for penile length in prepubertal Korean children be determined in studies with a larger community-based population in order to diagnose and treat size-related penile disorders.

A New Method of Vasovasostomy with the Prolene Stent

PURPOSE: The methods for vasovasostomy are varied, and many authors have reported various success rates. This study aimed to assess a new method for vasovasostomy with a Prolene stent. MATERIALS AND METHODS: Among 85 patients who underwent vasovasostomy with a Prolene stent, 69 patients were retrospectively reviewed at our hospital between October 2004 and December 2007. The average age at the time of vasovasostomy was 42.2 years (range: 24.0-52.0 years). The obstructive interval was 6.25 years (range: 0.7-20.0 years). The cases were divided into 2 groups according to obstructive interval: group A (above 8 years) and group B (8 years and less), with 18 (26.1%) and 51 (73.9%) cases, respectively. Patency was defined as a sperm concentration of more than 10x106/ml on semen analysis. RESULTS: The overall patency and pregnancy rates were 76.8% and 43.4%, respectively. The patency and pregnancy rates of group A were 61.1% and 33.3%. Those of group B were 82.3% and 47.0%. The mean duration to pregnancy was 10.9 months (range: 4-31 months). The mean operation time was 90.2 minutes (range: 50.0-165.0 minutes). CONCLUSIONS: The new method of vasovasostomy with the Prolene stent has good efficacy and safety. Its benefits are the maintenance of good patency, a good pregnancy rate, and a diminished operating time.

Renal Ruptures with Active Bleeding Treated with Emergency Selective Renal Arterial Embolization / 대한비뇨기과학회지

Selection of a treatment modality for traumatized renal rupture depends on the renal injury grade, hemodynamic stability, combined organ injury, and the physician's experience. Treatment for renal injury tends to be conservative to maintain renal function and lessen the morbidity of surgery. If renal injuries were well-staged and selected by radiologic evaluation, hemodynamically stable patients with significant injuries (grades II through V) can usually be managed without surgical exploration. We report 3 cases of grade 4 renal injuries successfully treated with selective renal arterial embolization.

Adenomatoid Tumor between the Epididymis and the Testis / 대한남성과학회지

Adenomatoid tumor is the most common paratesticular tumor with an anatomic distribution limited to the epididymis and it rarely invades to the tunica vaginalis, spermatic cord and ejaculatory duct. Adenomatoid tumor is a benign neoplasm that is thought to be of a mesothelial origin. The treatment of choice for adenomatoid tumor is local excision because of its benign nature and the absence of distant metastasis. We report here on a rare case of adenomatoid tumor that was found between the epididymis and the testis, and it was treated by local excision of tumor.

Solitary Fibrous Tumor as Misdiagnosed as Bladder Cancer / 대한비뇨기과학회지

Solitary fibrous tumor(SFT) was previously named localized fibrous mesothelioma, and this is a rare mesenchymal neoplasm that usually shows benign behavior. It is the most commonly recognized tumor of the pleura. These tumors have been recently reported to be found in unexpected locations. To the best of our knowledge, there have been only 2 reports of SFT arising from the urinary bladder in Koreans. We review this third case of SFT that was misdiagnosed as bladder cancer. This tumor was removed from a 40-year-old man who had a history of lower urinary tract symptoms.
