[Diagnosis of non-palpable testis in childhood: laparoscopy or magnetic resonance tomography?].

Laparoscopy and magnetic resonance imaging (MRI) are competetive tools in the diagnostic of non-palpable testis. Advantages and disadvantages of this methods will be demonstrate. 29 boys investigated for this indication with MRI. In case MRI failed to locate the testis laparoscopy was performed with a new miniaturized set of pediatric instruments (1.9 mm optic). The aim of laparoscopy was the identification of the spermatic duct and vessels and their topographic relation to the internal inguinal ring. All findings were verified by open surgical procedures. MRI revealed 10 inguinal and 7 abdominal testis. There was no false positive finding. In 12 boys MRI showed no testis. 4 cases were correct negative, 8 cases were false negative (32%). In these 8 MRI-negative patients laparoscopy revealed 7 inguinal and 1 abdominal testis. The optical quality of the mini-telescope was sufficient for a 100% correct diagnosis. Laparoscopy related complications did not occur. Laparoscopy proved to be a powerful low risk diagnostic method in non-palpable testis with high sensitivity and specifity (100% correct positive, 0% false negative). Therefore lapraroscopy is recommended as primary diagnostic access for this indication. In the same anesthesia a optimal therapy is possible. Nevertheless a positive MRI-finding locates the testis reliably, whereas a negative finding always needs further exploration because testis might have been missed.

[Diagnosis of non-palpable testis: value of a new miniaturized laparoscope].

Laparoscopy and magnetic resonance imaging (MRI) are competitive tools in the diagnosis of nonpalpable testis. We investigated 29 boys for this indication with MRI. If MRI failed to locate the testis, laparoscopy was performed with a new, miniaturized set of pediatric instruments (1.9-mm optic). MRI revealed 10 inguinal and 7 abdominal testes. There was no false-positive finding. In 12 boys MRI showed no testis. Four cases were true negative, 8 false negative (32%). In these 8 MRI-negative patients, laparoscopy revealed 7 inguinal and 1 abdominal testis. The optical quality of the mini-telescope was sufficient for a 100% correct diagnosis. Laparoscopy-related complications did not occur. In summary, laparoscopic evaluation is the preferred method in pediatric cases of nonpalpable testes.

[Increased incidence of mumps orchitis in adolescence and adulthood--sequelae of low vaccination rate?].

In recent years, mumps orchitis has become a rarely reported disease. However, since October 1994 a clear increase in the incidence of this disease has been observed. At four hospitals in the Saarland, Germany, 45 cases of mumps orchitis in adolescents and adults were diagnosed in this period. In addition to the case history and clinical findings, the diagnosis was confirmed by an increased IgM titer. None of the patients had been previously vaccinated. The main reason for this was a lack of parental knowledge of the necessity for this vaccination, one which has almost no side effects. The goal of this study is to describe the disease, present our own results, and indicate the need for vaccination. In addition to providing information, a further aim of the study is to increase the motivation of adolescents and adults for vaccination. Although many treatments for mumps have been published in recent years, the most successful therapy is still prophylactic vaccination.

[Retroperitoneal cystic lymphangioma in a child].

Cystic lymphangiomas are rare, benign tumors, which are mainly located in the neck or axilla. The fourteenth reported case in the literature of a pediatric retroperitoneal cystic lymphangioma is described. Symptoms, diagnostic procedure and therapy are reported and discussed.

[Congenital cysts of the seminal vesicles with ipsilateral kidney agenesis. Clinical aspects of 7 cases].

Seminal vesicle cysts with ureteral ectopy and ipsilateral renal agenesis or dysplasia are rare congenital malformations. This study reports 7 consecutive cases in a single center and, for the first time in the literature, reports long-term results on 5 cases. Patients were between the age of 15 and 57 years. The malformation was diagnosed in all cases with excretory urography, computed tomography, magnetic resonance imaging and cystoscopy. 5 patients were followed after diagnosis for 26 to 119 months (mean 52 months). Only 2 of 7 patients primarily presented with nonspecific lower urinary tract symptoms. One patient (15 years old) showed significant enlargement of the cysts with compression of the urinary bladder and signs of urinary incontinence 10 years after primary diagnosis. The other 4 patients had no changes of their malformation. In conclusion, seminal vesicle cysts with ipsilateral renal agenesis are now more frequently diagnosed because of the increasing use of sectional imaging procedures. They are mostly asymptomatic and their morphology does not change with time. These data support the concept of only treating symptomatic patients.
