RESUMEN

We herein present a regional review of the management of renal trauma in the west of Ireland. The majority of renal injuries occur as a result of blunt trauma and are amenable to conservative management. We sought to streamline the management of renal trauma in the west of Ireland. With the current restructuring of the Irish Health Service, it is important to acknowledge the role of the urologist in the management of trauma patients.

RESUMEN

OBJECTIVE: To analyse the long-term efficacy of combined interferon-alpha (IFN-alpha) and interleukin-2 (IL-2) subcutaneously, with 5-fluorouracil (5-FU) intravenously in a general multicentre setting, as treatment for metastatic renal cell carcinoma (RCC). METHODS: Fifty-nine patients with metastatic RCC were scheduled to receive an 8-week cycle of immunotherapy. Karnofsky score ranged from 70 to 100 (median 90). Thirty-one patients at presentation had metastases of which 14 underwent nephrectomy. Metastases occurred in multiple organs (lung 74%, mediastinal lymphadenopathy 22%, bone 21%). Therapeutic response and survival were analysed. RESULTS: Nine patients died from disease progression prior to completion of one full cycle. Six cases (10%) have stable disease at a follow-up of 51 months (range 20-88 months). Currently 11 patients (19%) are alive at a mean follow-up of 45 months (range 18-88 months). Forty-eight patients (81%) died of their disease at a mean follow-up of 10 months (range 0.5-46 months). Survival rate at 1 year was 53%, at 2 years 21%, at 3 years 16% and at 5 years 5%. Overall median survival is 10 months. CONCLUSION: IL-2 and IFN-alpha with 5-FU based immunotherapy achieve durable survival rates at 3 years in a minority of patients. Addition of 5-FU does not increase survival in our group. This study population is very different to other reported series. However it reflects better the entire population with metastatic RCC though results are subsequently poorer. Identifying patients that will respond is paramount.

RESUMEN

BACKGROUND: The Fowler-Stephens orchidopexy (FSO) is a well-described treatment for high maldescended testes where the limiting factor for successful placement in the scrotum is short testicular vessels. The operation involves division of these vessels. The testicular blood supply is then dependent on collaterals from the vasal artery. AIMS: To assess the long-term outcome of patients who underwent this procedure in our institution. METHODS: The medical records of 20 patients who underwent 22 FSO from 1978 to 1999 by one urologist (HB) were reviewed. Outcome was assessed in terms of testicular position and size. RESULTS: Age at operation ranged from 2 to 14 years (mean 5.8 years). All patients had a one-stage FSO and in two of them the procedure was bilateral. In five patients, FSO was preceded by a diagnostic laparoscopy. Mean follow up was 22 months (range 0-121 months). Overall, results were considered good in 18 of 22 testes (82%). CONCLUSION: Our results for the one-stage FSO are comparable with other procedures for the management of high maldescended testis.

RESUMEN

BACKGROUND: Laparoscopy can identify patients who would benefit from further surgical intervention. Most importantly it is 100% sensitive in identifying the vanishing testicle. AIMS: To review the role of laparoscopy in the management of the undescended testis. METHODS: Thirty-one patients underwent a laparoscopy for an impalpable testicle over a nine-year period at this institution. RESULTS: There were 30 successful laparoscopies completed for 31 impalpable testes,13 of which were normal. All underwent groin exploration of which 11 were located. Seventeen had an abnormal laparoscopy. Of these, 11 were located in the abdomen and four were diagnosed as vanishing testes. DISCUSSION: Sixteen per cent of patients had an absent testicle at laparoscopy and were spared any further surgical intervention. In the remaining 84%, over half had their surgical procedure altered as a result of the laparoscopic findings. This experience, has led us to believe that laparoscopy is a safe, reliable and sensitive procedure crucial to the management of the impalpable testis.

RESUMEN

BACKGROUND AND AIMS: The Marshall-Marchetti-Krantz procedure (MMK) is a vesico-urethral suspension, for the correction of urethral hypermobility in women with stress urinary incontinence. This study aims to describe the long-term outcome of the procedure. MATERIAL AND METHODS: 40 women with stress incontinence underwent the MMK. All operations were performed by one surgeon. Analysis of patients' notes yielded the early continence rate and perioperative morbidity. Long-term outcome was measured by means of a postal questionnaire with telephone contact to ensure maximum uptake. RESULTS: The immediate continence rate was 82%. Continence rates at up to 22 years follow-up (mean 8.5 years) is 61%. All failures occurred within 2 years of the operation. CONCLUSION: Patients still continent two years after the MMK will maintain continence in the long-term.

RESUMEN

OBJECTIVE: To analyse the toxicity and efficacy of combined interferon-alpha and interleukin-2, administered subcutaneously in a general multicentre setting, as treatment for metastatic renal cell carcinoma. METHODS: Thirty-three patients with metastatic renal cell carcinoma were scheduled to receive 2 cyclical doses of subcutaneous interferon-alpha (week 1: 5 MU x 3 days) and interleukin-2 (week 2: 36 MU x 2 days, 9 MU x 3 days; weeks 3-5: 9 MU daily). Karnofsky scores ranged from 80 to 100 (median 90). Metastases occurred in multiple organs (lung 63%, retroperitoneal 39%, liver 24%). Patients were categorised according to the risk of disease progression. Treatment toxicity, therapeutic response and actuarial survival were analysed. RESULTS: All patients received recommended doses of treatment, but 6 received less than 2 cycles. Most were treated as outpatients, although hospitalisation was usual during the 1st week of a cycle. All complained of mild flu-like symptoms. Severe side effects developed in 13 patients (39%), and treatment was discontinued in 3 of these patients. No deaths occurred as a result of treatment. The overall median survival was 10 months. The overall actuarial survival rate at 3 years was 22%. On statistical analysis, actuarial survival rates were not influenced by either response to treatment or risk group category. CONCLUSION: Subcutaneously administered, combined interferon-alpha and interleukin-2 therapy achieves durable survival rates in a minority of patients with renal cell carcinoma. Toxicity is remedial, and not fatal, when subcutaneous therapy is administered by multiple medical disciplines at a variety of centres.

RESUMEN

Carcinoma of the prostate is the commonest malignancy of the genitourinary tract in the male and is frequently associated with metastatic bone disease. Serial isotope bone scans for screening secondary deposits are not cost-effective. We have evaluated the serum prostate markers prostate-specific antigen (PSA) and prostatic acid phosphatase (PAP) as an alternative to conventional serial bone scanning in 129 patients with newly diagnosed prostate cancer over a period of 3 years. Although serum PSA did not reflect local tumour burden at presentation, it was significantly elevated in those who presented with stage D disease (p < 0.01). 45 patients presented de novo with metastatic bone deposits and a further 18 patients developed metastases during the study period. The sensitivity of PSA in detecting secondary deposits at presentation for levels in excess of 100 micrograms/l was 93.75%, the positive predictive value 95.7% and the negative predictive value for levels less than 5 micrograms/l was 90.6%. During the follow-up period the sensitivity was 94.4%, the positive predictive value 100% and the negative predictive value 100%, with a median lead time of 3 months in predicting metastases in the 18 patients with progressive disease. When compared with PAP, PSA was found to be a statistically superior marker of bone metastases both at presentation and follow-up (p < 0.05). We recommend that PAP measurements are no longer necessary and should be replaced by PSA, and that serial serum PSA estimations should determine the need for future isotope bone scans in the patient with established prostate cancer.

RESUMEN

We have analysed the accuracy of cytological examination of voided urine in a population of 265 patients presenting with suspected bladder lesions. Bladder carcinoma was confirmed by tissue histopathology in 51 patients. Of these, 42 were identified correctly by urinary cytology examination. Overall 34 patients were labelled as frankly malignant on cytology, of whom 2 were negative on final histology. 13 patients had been designated as suspicious however with 3 benign on final histological diagnosis. These data give a sensitivity for diagnosis of bladder cancer by urinary cytology of 82%, a specificity of 97%, a positive predictive value of 94%, and a negative predictive value of 96%.

RESUMEN

Fournier's gangrene or synergistic gengrene of scrotum and penis is a relatively rare but serious condition which can occur in any general or hospital practice. Early diagnosis with prompt aggressive treatment including antibiotics and surgical debridement are necessary to achieve patient survival. We report our clinical experience with three cases which occurred in three different hospitals in the Irish Republic. In two of these cases diabetes mellitus was an important predisposing factor. All three patients underwent surgery as well as antibiotic treatment in spite of which one patient failed to survive.

RESUMEN

An analysis of cystectomies performed between September 1, 1969 and December 31, 1974 was conducted to determine the rates of morbidity (59 per cent) and operative mortality (4.1 per cent). Comparison of these figures for single operations with data published form other sources concerning staging of the therapeutic procedures suggests that there is no benefit for the patient relative to surgical morbidity or mortality if the latter course is followed. Conversely, prolongation of hospital experience, multiple operations, absence from productive activity and increased health care cost are associated with the staged procedures. Application of cost-benefit analysis suggests that this experience may act as a model to evaluate competing forms of therapy involving other disorders. When costs are not equivalent and benefits are the same the more expensive form of therapy should not be offered except for unusual circumstances.

RESUMEN

Of 1,120 cases of ileal loop urinary diversion reviewed from our hospital 21 postoperative loop leaks were noted (1.87 per cent). Definite indications for diagnostic studies of urinary extravasation include persistent postoperative azotemia, sepsis and/or urinary leakage via the drains. In this series 2 types of loop leaks were noted--an early postoperative leak within the first 24 hours and a leakage 6 to 12 days postoperatively. More aggressive management of postoperatively urinary extravasation is urged, especially in patients who had been irradiated and suffered leakage later on in the postoperative course.
