Surveillance strategy for intratesticular cysts: preliminary report.

We treated 15 patients with all sonographic criteria of a simple testicular cyst. Of the patients 6 were operated on and the diagnosis was confirmed histologically, while 9 did not undergo an operation but are under close observation (mean surveillance 11 months). All patients are without any detectable malignancy. The possibility of a surveillance strategy in simple intratesticular cysts is discussed.

Has ultrasound influenced the therapy concept of blunt scrotal trauma?

We present the ultrasonic diagnoses and treatment of 44 patients with blunt scrotal trauma (rupture of the testis, hematocele, intratesticular hematoma and hematoma of the scrotal layers). Purely intratesticular hematoma without any other accompanying injury also can be detected sonographically. When massive scrotal swelling is present ultrasound is valuable to determine the status of the underlying testis even if discrete fracture planes of the tunica cannot always be detected. To achieve best long-term results early surgical intervention should be performed in cases of rupture of the testicle and hematocele, while hematoma of the scrotal layers and purely intratesticular hematoma can be treated conservatively.

Impact of sonography on diagnosis of scrotal diseases: a multicenter study.

Scrotal ultrasound was carried out since 1980 in five centers. 1,971 cases presenting with pathological conditions of scrotal content were reviewed to asses limitations and possibilities of the method. Scrotal sonography was found to be a highly reliable method to distinguish between intra- and extratesticular lesions. The data presented reveal that sonography is not capable of differentiating reliably between benign and malignant lesions. In the decision-making process ultrasound is sometimes of great help to the urologist but surely no substitution for careful examination and history taking.

Sonographic appearance of benign intratesticular lesions.

58 patients with a purely intratesticular lesion were investigated with scrotal ultrasound. A pathognomonic echo pattern could be found for simple parenchymal cysts and hemangiomas only. The nature of all other lesions (chronic orchitis, hematoma, epidemoid cyst, testicular necrosis, abscess and tuberculosis) could not be defined solely on sonographic grounds.

[Complications of preoperative arterial vascular embolization in malignant kidney tumors].

In 66 patients with renal tumours on 30 patients a preoperative transfemoral embolisation of the renal artery of the tumour-bearing kidney was performed. The complications were established and compared with the 36 patients without occlusion. On account of the considerable side effects a preoperative occlusion seems to be reasonable only in selected cases.

[Long-term observations following urinary drainage into the intact large intestine].

A report is given on 21 patients who have survived for at least 5 years after drainage of urine into the non-eliminated large intestine (Coffey-Mayo). Uretero-intestinal anastomosis was performed in 19 children, because of extrophy of the bladder, and in 2 women, following a malignant primary disease. In around half the patients there have been no complications during the post-operative observation period (on average 16.5 years), while new drainages had to be performed in the other half because of structures of the anastomoses. The patients have to adapt their daily lives to the "Coffey" and know the symptoms of an imminent electrolyte disturbance. Post-operative care must be arranged with the patient. Coffey's operation may be indicated when life expectancy is short; otherwise an antirefluxive ureterocolic anastomosis is recommended.
