    Eosinophilic cystitis associated with Glanzmann's thromboasthenia : a case report
    (Health & Medical Publishing Group, 1987) Botma, J. P.; Burger, E. G.; De Kock, M. L. S.
    Eosinophilic cystitis is a rare condition, only 41 cases having been recorded in the literature. Glanzmann's thrombasthenia has been documented more than 100 times. The presence of these two conditions in one patient has, to our knowledge, not yet been reported in the English-language literature.

    Epidemiology of urethral stricture at Tygerberg Hospital
    (Health & Medical Publishing Group, 1994) Steenkamp, J. W.; De Kock, M. L. S.
    Over a 12-month period, 120 consecutive male patients with confirmed urethral stricture were prospectively studied with regard to the epidemiology of the disease. Specific urethritis is the main aetiological factor (45%) and internal and external trauma account for an alarming 38,3% of cases. The prevalence is highest among 40 - 50-year-old coloured men who have had little schooling, multiple sexual partners and who have a low annual income. The incidence can be reduced by upliftment of moral and educational standards of the local population, and by emphasising the potential dangers of catheterisation and instrumentation to medical personnel.

    Extra-adrenal phaeochromocytoma. A case report
    (Health & Medical Publishing Group, 1986-01) Botma, J. P.; De Kock, M. L. S.
    ENGLISH ABSTRACT: A case of hypertension in a young woman caused by an extra-adrenal phaeochromocytoma (EAP) situated in the hilum of the left kidney is reported. Surgical removal of the EAP resulted in control of the patient's hypertension without further drug treatment. The clinical features, diagnostic work-up and management of EAP are briefly discussed.

    Genito-urinary tuberculosis : experience with 52 urology inpatients
    (Health & Medical Publishing Group, 1993) Allen, F. J.; De Kock, M. L. S.
    The current trend in South African health services is toward primary care. Pulmonary tuberculosis is well understood by the majority of primary care doctors and nurses, whereas genito-urinary tuberculosis may not be as easy to diagnose and treat. We reviewed our experience with this condition in 52 patients, who represented 0,74% of urology admissions between 1986 and 1991. There was a 3:2 male/female ratio, the age range was 7-76 years (mean 43 years), and the disease was more common among blacks and coloureds than among whites. Multiple sites of involvement were fairly common. Seventy-five per cent of patients had renal involvement and 17% epididymal involvement. The commonest presenting complaints were urinary frequency and haematuria, although flank and scrotal pain were also reported by a number of patients. Physical examination seldom helped to suggest the diagnosis. On microscopic examination and culture of the urine, sterile pyuria was present in only 50% of our patients and 29% had positive cultures for a 'normal' coliform organism. Fifty patients underwent excretory urography and the findings were very varied. Patients were treated primarily with antituberculosis drugs, but 58% also required some form of surgery; nephrectomy was the commonest operation. Ureteral strictures developed in over 50% of cases with renal involvement. We conclude that the diagnosis of genito-urinary tuberculosis is not simple, and that treatment must include regular follow-up at a specialist institution.

    Intravesikale BCG as behandeling van herhalende oppervlakkige en in situ oorgangselkarsinoom van die blaas
    (Health & Medical Publishing Group, 1990) Schmidt, A. C.; De Kock, M. L. S.; De Klerk, D. P.
    Intravesical BCG is already established as effective therapy in the management of superficial bladder cancer. However, varying results have been obtained with different BCG strains; these are ascribed to variations in their immunogenicity. The locally available BCG strain which contains approximately 1.2 x 109colony-forming units per 120 mg was used for intravesical instillation in 27 patients with recurrent superficial transitional cancer of the bladder. Ten of the 13 patients who received BCG prophilactically to reduce or stop recurrencies completed therapy and 7 (70%) were in remission after 1 or 2 courses with a mean follow-up of 2 years. Fourteen patients received BCG therapeutically for in situ carcinoma. Thirteen of these patients completed therapy and 9 (69%) responded favourably after 1 or 2 courses of BCG for a mean follow-up period of 23 months. Adverse effects of the treatment were mild and well tolerated except in a patient who received radiotherapy. Although 21 patients experienced irritable bladder symptoms only 1 discontinued treatment as a direct result. The only other patient in whom treatment had to be stopped, developed severe polyarthritis after 3 instillations. A statistically significant reduction in the number of recurrences (P < 0.001) was experienced by the patients who received BCG prophylactically. Although this is a very limited study, the locally available BCG strain exhibited therapeutic activity. It is cost-effective and warrants further study.

    Malignant fibrous histiocytoma of the spermatic cord: A case report
    (Health & Medical Publishing Group, 1987-03) Botma, J. P.; De Kock, M. L. S.; Laubscher, W. M. L.
    A case of malignant fibrous histiocytoma of the spermatic cord treated by primary local excision, followed 5 days later by radical inguinal orchidectomy and hemi-scrotectomy is reported. At 30 months' follow-up the patient is free from local recurrence.

    Nieroorplanting by die Tygerberg-hospitaal : 'n oorsig van chirurgiese komplikasies
    (Health & Medical Publishing Group, 1982) De Kock, M. L. S.; Schmidt, A. C.; De Klerk, J. N.
    From May 1976 until January 1981 74 patients received 76 renal transplants at Tygerberg Hospital. Forty-one patients (55%) developed at least one surgical complication. Four patients (5.4%) died from widespread sepsis. In this article we review the possible causes of and preventive measures against surgical complications after renal transplantation.

    Percutaneous nephrolithotomy : experience with renal and proximal ureteral calculi at Tygerberg Hospital
    (Health & Medical Publishing Group, 1988) Van Niekerk, L. R.; De Klerk, D. P.; De Kock, M. L. S.; Schmidt, A. C.; Stockland, B.
    Percutaneous nephrolithotomy (PCN) enables the urologist to remove upper urinary tract stones through a percutaneous nephrostomy tract. The principal advantages of PCN are the low morbidity, shortened hospital stay and rapid recovery. Percutaneous puncture failed in 5 (11%) of the first 44 patients with upper tract urolithiasis treated by PCN at Tygerberg Hospital. In 35 patients (80%) PCN cleared the kidney of stones but in 4 patients (9%) all stone fragments were not removed during the procedure. If the puncture and dilatation was successful, then 90% of patients were stone-free after PCN. Complications were minimal except for a diabetic who died of septicaemia. PCN is an alternative to open renal surgery in the management of most upper urinary tract stones. The technique is readily mastered by any urologist experienced in endoscopic surgery.

    The suprapubic approach in the surgical treatment of female stress incontinence
    (Health & Medical Publishing Group, 1982) De Kock, M. L. S.; De Klerk, J. N.
    Stress incontinence in women is a frequent and humilating complaint, the aetiology and pathogenesis of which are not always apparent. Routine investigation followed by standard vaginal or abdominal surgical procedures will cure most uncomplicated cases. However, in complicated cases a more sophisticated pre-operative evaluation and a more versatile surgical approach are indicated in order to restore the changed anatomy and function.

    Transurethral prostatectomy - studies with different intravesical pressures
    (Health and Medical Publishing Group -- HMPG, 1982-05) Rabe, H. B.; De Kock, M. L. S.
    In an attempt to study the safety of transurethral prostatectomy in our unit, the use of a low-pressure continuous-flow water irrigation system was compared with our routine method of intermittent bladder emptying during transurethral prostatectomy in 14 patients. The products of haemolysis and parameters of haemodilution were studied, and no significant differences were noted. However, a simple suprapubic shunt provided significant surgical advantages.
