Xanthogranulomatous pyelonephritis: Analysis of 18 cases.

OBJECTIVE: To review and evaluate patients with a clinicopathological diagnosis of xanthogranulomatous pyelonephritis (XGP) with emphasis on the diagnostic methods and the effect of socioeconomic status on disease severity. METHODS: Data compiled from the previous history of the patients, clinical, laboratory, radioimaging findings, preoperative, operative, histopathological diagnosis and postoperative follow-up period were analysed. On the basis of presentation, XGP was classified as complicated and simple. RESULTS: There were 18 cases of XGP. The clinical characteristics included: calculi or obstruction in the urinary tract, and damage to the kidney, complication of urinary tract infection, anaemia, increased erythrocyte sedimentation rate and liver dysfunction. All patients had diffuse XGP. Associated pathological findings such as psoas abscess, nephrocutaneous fistula, renocolonic fistula and paranephric abscess were found in 33.3% of cases. Eleven of 14 patients (78.6%) who were evaluated by computed tomography (CT) had the correct diagnosis made prior to nephrectomy. Urine culture was positive in 88.9% of patients and Proteus mirabilis was the most common organism. CONCLUSION: Our experience with a small number of patients demonstrates that low socioeconomic status could be a risk factor in the development of complicated cases of XGP. CT is considered to be the best radiological test for correct preoperative diagnosis and evaluation of XGP. Nephrectomy and removal of all surrounding affected tissue proved to be curative for XGP.

A prospective randomized trial comparing transurethral prostatic resection and clean intermittent self-catheterization in men with chronic urinary retention.

OBJECTIVE: To determine whether a preliminary period of clean intermittent self-catheterization (CISC) before transurethral resection of the prostate (TURP) improves bladder contractility and surgical outcome in men with chronic urinary retention (CUR), and whether pressure-flow studies (PFS) before TURP predict the outcome. PATIENTS AND METHODS: The study was a two-centre, pragmatic and randomized trial. Included were 41 men scheduled for TURP with lower urinary tract symptoms (LUTS), an International Prostate Symptom Score (IPSS) of > 7, benign prostatic enlargement and a persistent postvoid residual urine volume (PVR) of > 300 mL. They had conventional PFS using unphysiological filling. The patients then gave consent and were randomized into two treatment groups; the first had TURP after stabilizing renal function by indwelling catheterization if indicated, and the second was taught CISC. Men in both groups were reviewed at 3 and 6 months after surgery or the start of CISC, by the IPSS, urine culture and assay of plasma creatinine, and upper tract imaging and repeat PFS at 6 months. The primary outcome variables were IPSS, maximum urinary flow rate, voiding and end-filling pressures, and mean PVR; secondary variables included treatment failure, complications and other urodynamic measures. RESULTS: Of the 41 patients, 17 (mean age 67 years, range 52-84) were randomized to immediate TURP and 24 (mean age 69 years, range 55-85) to CISC. There was a significant improvement in IPSS and quality of life at 6 months in both groups (P < 0.001). In the CISC group there was a significant improvement in voiding and end-filling pressures, indicating recovery of bladder function (P < 0.001 for each). Of the 41 men, nine (22%) with voiding pressures of < or = 45 cmH2O had no significant improvement in symptoms or urodynamic variables. Detrusor overactivity was found in 17 (41%) patients, of whom six had upper tract dilatation which resolved after treatment. CONCLUSION: The present results emphasize the usefulness of CISC in ensuring the recovery of bladder function in men with CUR. Measuring the voiding pressure before TURP can predict the surgical outcome. Both CISC and immediate TURP are effective for relieving LUTS and result in a better quality of life. A preliminary period of CISC before TURP for men with CUR and low voiding pressure may be valuable. The presence of upper tract dilatation is associated with high end-void and end-fill bladder pressures, and such men have a good outcome from surgery.

Ultrasound-guided transrectal extended prostate biopsy: a prospective study.

AIM: To evaluate the diagnostic value of the 10 systematic transrectal ultrasound-guided (TRUS) prostate biopsy compared with the sextant biopsy technique for patients with suspected prostate cancer. METHODS: One hundred and fifty-two patients with suspected prostate cancer were included in the study. Patients were entered in the study because they presented with high levels of prostate specific antigen (PSA) (over 4 ng/mL) and/or had undergone an abnormal digital rectal examination (DRE). In addition to sextant prostate biopsy cores, four more biopsies were obtained from the lateral peripheral zone with additional cores from each suspicious area revealed by transrectal ultrasound. Sextant, lateral peripheral zone and suspicious area biopsy cores were submitted separately to the pathological department. RESULTS: Cancer detection rates were 27.6% (42/152) and 19.7% (30/152) for the 10-core and sextant core biopsy protocols, respectively. Adding the lateral peripheral zone (PZ) to the sextant prostate biopsy showed a 28.6% (12/42) increase in the cancer detection rate in patients with positive prostate cancer (P < 0.01). The cancer detection rate in patients who presented with elevated PSA was 29.3% (34/116). When serum PSA was 4-10 ng/mL TRUS-guided biopsy detected cancer in 20.6%, while the detection rate was 32.4% and 47.0% when serum PSA was 10-20 ng/mL and above 20 ng/mL, respectively. CONCLUSION: The 10 systematic TRUS-guided prostate biopsy improves the detection rate of prostate cancer by 28.6% when compared with the sextant biopsy technique alone, without increase in the morbidity. We therefore recommend the 10-core biopsy protocol to be the preferred method for early detection of prostate cancer.

Pathological spectrum of nephrectomies in a general hospital.

OBJECTIVES: To first categorize a series of nephrectomies according to underlying pathology, as practised in a major general hospital in the north of Jordan, and then compare the results with published figures for Western countries. Also, to create standards for future evaluation of nephrectomies performed by laparoscopy. METHODS: The hospital and pathological records of 423 consecutive nephrectomies performed at Princess Basma Teaching Hospital in the north of Jordan during the period of 1991 to 2000 were reviewed. RESULTS: Benign disease led to surgery in 298 cases, of which 161 were secondary to infection-related conditions. Malignancy resulted in the removal of 125 kidneys. The rate of nephrectomy for benign conditions has declined during the last few years in comparison with that for malignant conditions. Patients operated on for benign diseases were younger [mean age, 38.4 years] than those with malignant tumours [mean age, 46.7 years]. CONCLUSIONS: The mean age of patients undergoing surgery for benign and malignant disease was lower than in publications from Western countries. The frequency of nephrectomy performed for tuberculosis, hydatid disease, and xanthogranulomatous pyelonephritis is still higher than the rates published in Western countries. There is a remarkably low frequency of upper urothelial carcinoma compared with Western countries, probably due to environmental differences and genetic susceptibilities. Malignant renal tumours tend to affect people at a remarkably young age in Jordan, which is thought to be a reflection of the high proportion of young people. Nephrectomy for malignant disease had a higher rate of complications (16.8%) than for benign conditions [9.4%; p less than 0.0228]. The re-operation rate was 3.1% for all patients who underwent nephrectomy. The overall 30-day mortality rate was 0.9%. Both screening and education programmes are needed to decrease the rate of nephrectomy for preventable conditions.
