We report five patients who presented with seminoma of an undescended testis to highlight the importance of dealing with adult cryptorchidism. On the basis of the literature review and our experience, we advocate orchidectomy for post-pubertal cryptorchid patients of any age because follow-up may be difficult, and treatment for the tumour may be unsuccessful.
A patient who was troubled by the persistent passage of prostatic calculi following transurethral prostatectomy is reported. The pathogenesis of these calculi is postulated.
We report a rare case of suppurative epididymo-orchitis caused by Pseudomonas pseudomallei in a 56-year-old male. This is a gram negative bacillus found mainly in tropical zones. Diagnosis was reached by culture of the organisms after drainage of the scrotal abscess, and the patient was treated by a course of oral chloramphenicol 500 mg qid for 6 months.
Xanthogranulomatous pyelonephritis is a clinico-pathological entity that is gaining awareness amongst urologists worldwide. It is an unusual chronic inflammatory lesion involving the kidney that destroys renal parenchyma and may mimic renal carcinoma. It is usually seen in middle-aged women and is associated with urinary tract infections and urinary calculi. Most reports and reviews of this condition come from the West; this study reviews the incidence and presentation of the condition in a Malaysian population.
Angiomyolipomas are rare tumours of the kidney which have a tendency to bleed. We studied the clinical and radiological features of 11 patients from our institution to identify features which may be predictive of a massive haemorrhage. Tumours more than 6 cm in diameter were found to bleed and the demonstration of pseudoaneurysms on contrast CT scanning was associated with massive haemorrhage. We conclude that large angiomyolipomas should be treated to avoid haemorrhage and the detection of pseudoaneurysms should prompt urgent treatment.
A retrospective review of 80 patients who underwent scrotal exploration for presumed testicular torsion is presented. Of these, 67 patients were found to have torsion, and the testicular loss rate was 51%. Patients who experienced delays in scrotal exploration of more than 24 h from onset of symptoms had a testicular loss rate of 71%. These delays arose from both hesitation in seeking medical treatment and misdiagnoses. It is emphasized that an acute scrotum in a child or in an adolescent should be explored early to exclude torsion.
A retrospective review of 107 patients operated on for multinodular goitre was carried out to determine the incidence of carcinoma. Of the group 7.5 per cent harboured incidental carcinomas with papillary carcinoma being the most common variety. The indications for removal of multinodular goitre should be compressive symptoms, suspicion of malignancy and cosmesis.
The treatment of perforated duodenal ulcer is controversial. Since the advent of H2 antagonists, the number of ulcer operations has declined tremendously. We wanted to find out if the addition of a H2 antagonist after simple closure of a perforated duodenal ulcer would change the outcome and therefore reviewed 46 patients treated in this fashion. Our results show that this is a safe and effective way of treating patients with perforated duodenal ulcer.
Four cases of emphysematous pyelonephritis are reported and the pathogenesis, surgical implications and preferred mode of management are discussed. We have not found percutaneous drainage to be useful, but feel there is an important place for surgical drainage alone because of the potential for renal recovery and the risks of emergency nephrectomy.
Recto-prostatic fistula is a rare complication of prostatic surgery, occurring usually because surgical planes are not appreciated. We describe a combined abdomino-perineal approach for the repair of a large recto-prostatic fistula with the interposition of omentum and gracilis without formally closing the fistula in layers.
Five cases of renal angiomyolipoma which underwent spontaneous rupture are described. These patients presented as an "acute abdomen" for which the diagnosis was not initially apparent. A high index of suspicion is required to make the diagnosis even with modern imaging techniques. The treatment of these tumours is discussed.
Primary germinomas of the central nervous system carry a good prognosis because of their radiosensitivity. Recurrences are rare and extraneural metastases are even more unusual. One of the possible routes of extraneural spread is via ventriculo-peritoneal shunts which may be required to reduce intracranial pressure. One such case of germinoma metastasizing via a ventriculo-peritoneal shunt is reported. Patients with intracranial germinomas and ventriculo-peritoneal shunts should have close surveillance of their abdomens and may require systemic chemotherapy.
Spinal involvement in alkaptonuria is common. Patients usually present in the third or fourth decade with spondylosis or acute intervertebral disc prolapse. Alkaptonuria with root canal stenosis has however hitherto not been reported. We wish to report one such patient.
