Aims To translate and validate the Arabic version of the short form of Urogenital Distress Inventory (UDI-6) questionnaire in a sample of women with lower urinary tract symptoms (LUTS). Methods Two native Saudis independently translated the original UDI-6 into Arabic. These two translations were harmonized, and then checked by independent back translation by two English teachers. They collaborated with the clinical investigators to reach a consensus version of the questionnaire. The harmonized version was pre-tested in a pilot study on 20 patients. The final version of the UDI-6 was applied to 68 consecutive patients aged 22 years or over complaining of LUTS for at least 3 months at our tertiary care hospital. The patients were rerated after 1 week to assess test–retest reliability. To assess the capacity of the questionnaire to discriminate between women with and without LUTS, cases, and controls of healthy women sample were involved and assessed. The psychometric properties of the questionnaire, such as reliability and validity were assessed. Results The correlation co-efficient between ratings was >0.75 and the discriminate power between cases and control were confirmed. The UDI showed good internal consistency total score cronbach α = 0.71. Conclusions The Arabic version of UDI-6 is a valid and robust instrument and a reliable method to use in daily practice and clinical research. Neurourol.

Objectives To evaluate the changing management of sporadic renal angiomyolipoma and renal angiomyolipoma associated with the tuberous sclerosis complex (TSC) during the past 16 years. Methods We retrospectively reviewed the charts of 60 patients with angiomyolipoma seen at our institutions. Results The median age at presentation was 45 years (range 7-78). The presentation was pain in 30 patients and hematuria in 13; it was incidentally discovered in 17 patients. Of the 60 patients, 43 were females. TSC was present in 14 patients. The median tumor size was 4 cm (range 0.3-40, mean 6.5 ± 1.1). Of the 60 patients, 31 were followed up expectantly. Surgery or intervention was needed for 29 patients to control hemorrhage or relieve pain or because of the suspicion of malignancy. Of these 29 patients, 12 underwent nephrectomy, 11 partial nephrectomy, and 6 embolization. The patients treated for hemorrhage had a median tumor diameter of 11 cm (range 2-21). Patients were followed up for a mean of 39.3 ± 5.4 months. The lesions grew an average of 4.7 ± 3.4 cm for TSC tumors and 0.6 ± 0.2 cm for sporadic angiomyolipoma tumors. None of the patients developed renal impairment. Patients with TSC presented at a younger age, had larger and bilateral lesions, and were more symptomatic during follow-up. In the past 6 years, a significant trend was seen toward finding tumors in asymptomatic patients and toward the use of conservative or interventional (embolization) treatment. Conclusions Renal angiomyolipoma has a slow growth rate. The preservation of renal function was noted in all our patients. A recent shift was noted toward finding smaller tumors in asymptomatic patients and the use of conservative and interventional treatment.

Purpose The purpose of the study was to identify the spectrum of disease characteristics of pheochromocytoma in children. Methods Records of 21 consecutive children diagnosed with pheochromocytoma were reviewed. Patients' age, sex, presentation, associated conditions, diagnostic and imaging modalities used, preoperative preparation, operative details, outcome, and follow-up were recorded. Results The study included 21 children. Patients were diagnosed clinically and confirmed by biochemical tests. Tumors were localized by imaging studies and all were confirmed pathologically. Patients included 17 with adrenal and 4 with extra-adrenal tumors including 1 in the urinary bladder. Seventeen had sporadic and 4 had familial pheochromocytoma. Associated manifestations were the predominant features in 1 of the 4 patients with familial pheochromocytoma. The patient with bladder pheochromocytoma presented with gross hematuria. Hypertension and visual disturbances were prominent findings in the other patients with sporadic form. Two patients (1 sporadic and 1 familial) had malignant pheochromocytoma. One patient with benign pheochromocytoma had multiple recurrences in chromaffin-containing sites. All patients were treated surgically. Seventeen patients were treated preoperatively with alpha-adrenergic blockade. Two patients continued to have significant visual disturbances. One patient with malignant pheochromocytoma died of the disease, and 1 with recurrent pheochromocytoma had neurologic consequences. Conclusions Pheochromocytoma in children has unique characteristics. To our knowledge, this series is one of the largest reports of adrenal pheochromocytoma in children. It also reflects the spectrum of pheochromocytoma in this age group.

We present our experience of two cases with genitourinary manifestations of Klippel-Trenaunay syndrome. A MEDLINE search for the period 2001-2004 was done using the keywords "Klippel-Trenaunay syndrome", "vascular malformation" and "genitourinary". Only three cases with genitourinary manifestations of this syndrome were reported during this period. Genitourinary problems are rare in Klippel-Trenaunay syndrome; however, their management may be a challenge for the urologist. In one of our patients who failed to respond to endoscopic laser coagulation and partial cystectomy we used systemic alpha-interferon, with a good short-term response.

We report a case of a symptomatic giant (18 x 10 x 8-cm) renal cyst in a 40-year-old woman that was marsupialized laparoscopically and excised. The surgical technique, based on progressive decompression of the cyst, is fully described. Excellent results were achieved. The recent application of laparoscopic ablation of different types of renal cysts is reviewed. This minimally invasive technique, when properly mastered, is highly effective and offers results similar to those of open surgery. It is associated with definitive postoperative advantages and is the treatment of choice for very large renal cysts, especially those located anteriorly, when sclerotherapy is ineffective or is contraindicated.

Purpose: Idiopathic retroperitoneal fibrosis is an uncommon disease of unknown etiology that may involve the ureters and other retroperitoneal structures. Surgical ureterolysis as well as medical treatment with steroids have been used to treat these patients. However, there is no agreement as to the dose and duration of steroid. We adopted a regimen of long-term steroid use in this prospective study.Materials and Methods: We treated 12 patients with idiopathic retroperitoneal fibrosis with a regimen of steroids during a 10-year period. Tissue diagnosis was established by biopsy of all lesions and ureteral obstruction was managed with insertion of a nephrostomy tube or a ureteral stent. The initial dose of prednisolone was 60 mg. on alternate days for 2 months and was tapered during the following 2 months to a daily dose of 5 mg. The total duration of prednisolone use was 2 years.Results: Of the 12 patients 11 who completed this treatment regimen have been followed for a duration of 26 to 132 months (media...

Background and Objective Evaluate the efficacy and toxicity of alternating intravesical instillation of Bacillus Calmette-Guerin(BCG) and Interferon alpha2-b (IFN) in the treatment and prevention of recurrence of superficial transitional cell carcinoma (TCC) of the urinary bladder. Methods Patients with Ta, T1 tumors and carcinoma in situ, either recurrent (TaG1, T1G1) or primary/recurrent TaG2 TaG3, T1G2, T1G3 and Tis (T: Tumor stage, G: grade) are eligible. All patients received intravesical BCG 81 mg on Weeks 1, 3, 5 and 7 and IFN 100 million units on Weeks 2, 4, 6 and 8. Cystoscopy performed 4 weeks after completion of therapy, and every 3 months thereafter. Results There was a total of 37 patients. Thirteen had TaG2, 13 T1G2, 1 T1G1, 4 TaG1, 1 TaG3, 3 T1G3 and 7 Tis (5 concurrent with other above tumors). Index lesion cleared in 7/10 patients. With a median follow-up of 26.2 month, 22 patients (59%) failed above therapy. Median time to treatment failure was 7 months. Seven, 6 and 9 patients recurred at a higher, lower and same stage or grade respectively. No grade 3 or 4 toxicity was encountered. Conclusions Alternating intravesical BCG and IFN is effective and well tolerated therapy for superficial TCC of urinary bladder. J. Surg. Oncol. 2000;74:181–184. © 2000 Wiley-Liss, Inc.

To identify disease characteristics, operative outcome, and prognosis in patients with familial pheochromocytoma.Records of 29 patients with familial pheochromocytoma were retrospectively analyzed. Patients' age, gender, presenting symptoms and clinical signs, chemical and radiologic findings, and associated conditions were recorded.Of the 29 patients, 25 were adults and 4 were children. Age ranged from 18 to 52 years (mean age 30.8 years). Twenty patients were females. Of the 29 patients, 26 had adrenal tumors, 2 had extra-adrenal tumors, and 1 had a combined adrenal and extra-adrenal tumor. The patients included 17 with multiple endocrine neoplasia (MEN), 8 with von Hippel Lindeau disease (vHLD), and 4 with Von Recklinghausen disease (vRD). Two patients had malignant pheochromocytoma. All except one patient with MEN had thyroid carcinoma. The two patients with malignant pheochromocytoma had MEN II. All patients were managed by either open or laparoscopic adrenalectomy or excision of extra-adrenal tumors. There was no perioperative mortality.Associated conditions in patients with familial varieties are often the dominant or initial presentation. Presence of other manifestations of familial pheochromocytoma significantly influenced the clinical course and prognosis. However, it had no bearing on operative outcome of these patients.

Purpose: Goal oriented therapy for erectile dysfunction, based on a complete education of the couple, was offered to 460 patients. The short-term and long-term results of the first and second treatments selected were compared.Materials and Methods: From September 1991 to March 1995, 460 patients with erectile dysfunction were evaluated and treated prospectively. The success of treatment, selected by the patient or couple, was defined as the ability to achieve and maintain good erections for successful coitus for at least 1 year after the start of therapy. Sexual satisfaction of the couple was required to confirm a successful outcome.Results: The preferred first line of treatment by 322 patients was pharmacotherapy, with intracavernous injections being the second most selected therapy (80% success rate). However, there was a high long-term dropout rate for intracavernous injections. Approximately 70% of the patients were lost to followup or refused further treatment.Conclusions: Overall, this prosp...

Background: Ureterovesical and vesicovaginal fistulae usually are easily diagnosed with standard techniques, including radiology, double-dye test, cystoscopy, and vaginal examination. In a few complex cases, however, the localization of the fistulous orifice may be extremely difficult. Method: We describe a novel technique of retrograde vaginal methylene blue testing that may assist in the proper localization of the fistulous opening. Results: Our experience with one case each of ureterovesical and vesicovaginal fistula easily diagnosed with this method proves its efficacy, simplicity, and safety. Conclusion: This technique should be reserved for cases of urinary fistulae when all standard diagnostic methods have failed.

Prostate adenocarcinoma often presents at a late stage, due to a lack of early clinical symptoms and lack of accurate objective markers. This study aimed to identify and validate proteomics-based biomarkers useful for prostate cancer diagnosis and to establish a marker-panel for prostate cancer and benign prostate hyperplasia (BPH). Global protein expression patterns in fresh tissue specimens from 8 patients with prostate carcinoma and 16 with BPH were analyzed by two-dimensional gel electrophoresis. Differentially expressed proteins were identified by MALDI-TOF mass spectrometry. We compared our results with those of published studies and defined a set of common biomarkers. We identified 22 differentially expressed proteins between BPH and prostate carcinomas. The up-regulated proteins in cancer compared to BPH included protein disulfide-isomerase, 14-3-3-protein, Enoyl CoA-hydrase, prohibitin and B-tubulin β-2. Keratin-II, desmin, HSP71, ATP-synthase-β-chain and creatine kinase-β-chain were down-regulated. Survey of the literature showed that 15 of our 22 identified proteins have been previously reported to differ in their expression levels between BPH and prostate cancer by other laboratories. The expression patterns of these biomarkers could successfully cluster BPH and adeno-carcinomas as well as prostate cancer of low and high Gleason scores. This study validates protein-biomarkers that can be useful for accurate diagnosis and prognostic monitoring of prostate adenocarcinoma. Despite varied prevalence of the disease between different ethnic populations (i.e., high in Sweden, low in Saudi Arabia); the biomarkers indicate that BPH and prostate cancers are biologically 'homogeneous' in their protein expression patterns across wide geographical regions.

The incidence of prostate cancer in Saudi Arabia has been reported to be low at 1.4 to 2.1/100,000 person-years. We prospectively evaluated the true incidence of this disease and its association with dietary factors.From 1994 to 1997 inclusive Saudi men older than 50 years treated at our institution for various presenting symptoms and diseases were randomly selected from various departments. They were examined prospectively with digital rectal examination, and total and free prostate specific antigen measurement. Transrectal ultrasound and prostatic biopsy were performed when either test was abnormal. Nutrition questionnaires and detailed interviews with a nutritionist were completed to assess the type of diet, and amount of saturated and polyunsaturated fat consumption of patients with prostatic carcinoma and controls.For the 2,270 Saudi men screened we noted an incidence of 3.1/100,000 person-years. Our nutritional survey revealed that recent fat consumption was greater than 120 gm. per person daily, of which about 40% was from meat and dairy products. Saturated fat comprised about 50% of the total fat intake. There was no difference in the amount of fat in the diet of men with and without prostatic carcinoma.The incidence of prostatic carcinoma in the Kingdom of Saudi Arabia is low despite a high saturated fat diet in recent years. This finding contradicts most western clinical studies, which indicate a positive association of a high fat diet with prostatic carcinoma.

OBJECTIVE To analyse the presentation, manifestations and outcome in consecutive patients with phaeochromocytoma, as this disease has a wide range of pathological and clinical expressions. PATIENTS AND METHODS The records of 115 patients with phaeochromocytoma were analysed retrospectively, recording the patients’ age, sex, presenting symptoms and clinical signs, chemical, radiological and pathological findings and associated conditions. RESULTS Of the 115 patients, 90 had adrenal tumours, 18 extra-adrenal and seven combined adrenal and extra-adrenal tumours. Ten patients had malignant and 105 had benign phaeochromocytoma. Eighty-six patients had sporadic and 29 had familial phaeochromocytoma, comprising eight with von Hippel-Lindau (VHL) disease, 17 with multiple endocrine neoplasia type II (MEN II) and four with von Recklinghausen disease. Two patients with sporadic phaeochromocytoma had Grave’s disease. Ten patients (8.7%) had malignant phaeochromocytoma, of whom two had MEN II. A pregnant woman required prolonged intensive-care management before adrenalectomy and lost a fetus. CONCLUSION Phaeochromocytoma is an interesting clinical entity with a wide spectrum of pathological and clinical manifestations. The diagnosis of phaeochromocytoma is confirmed by chemical methods, and located using imaging techniques, with computed tomography, magnetic resonance imaging and 131I-meta-iodobenzyl guanidine radioisotope scanning being the most common. This series reflects the pathological and clinical spectrum of phaeochromocytoma. The presence of other manifestations of familial phaeochromocytoma influenced the presentation and prognosis of these patients.

Introduction Correction of penile deformity caused by Peyronie's disease by a variety of grafts varies in success. A long-term follow-up shows a significant number of graft scarring and erectile dysfunction. The clinical success of autologous crural tunica albuginea graft (TAG) has not resulted in wide application. Aim To identify in healthy baboons the limitations and merits of autologous crural TAG over 1 year in a way difficult to pursue in humans. Methods Under general anesthesia, eight sexually active adult baboons underwent pharmacological cavernosometry (CM) and cavernosography. TAG from crus was implanted in the distal penile shaft. After 6 months, six animals were reevaluated and two were sacrificed, and the penises were excised. After 1 year, the remaining six animals were evaluated and sacrificed. The TAG and underlying corpus cavernosum (CC) were examined histologically and by Western blot analysis for nitric oxide synthase (NOS), neuronal (nNOS), endothelial (eNOS) and inducible (iNOS) isoforms, and transforming growth factor-β 1 (TGF-β 1 ). Main Outcome Measures Sexual activity, CM, cavernosography, histopathology, and Western blot analysis. Results All animals resumed normal sexual activity 1 month postsurgery. Cavernous pressure was comparable before, at 6 months, and 1 year after surgery. A cavernovenous insufficiency developed in four animals at 6 months, and ceased in two at 1 year. Penile angulation ( 1 levels. In TAG, there was no significant change in TGF-β 1 and eNOS levels, but there was a significant decrease in iNOS at 1 year. Conclusions Autologous free TAG is associated with normal sexual activity, minimal hemodynamic changes, excellent histological outcome, and no rise in iNOS or TGF-β 1 . However, cavernovenous insufficiency, mild penile angulation, and decreased nNOS persisted at 1 year. Seyam RM, Mokhtar AA, Chishti MA, Ahmed M, Mourad WA, El-Sayed R, and Hanash KA.

Objectives. To evaluate the justification of routine removal of ipsilateral adrenal gland as part of radical nephrectomy for renal cell carcinoma (RCC). Methods. The medical records, pathologic specimens, and computed tomographic (CT) scans of 77 patients who underwent radical nephrectomy and ipsilateral adrenalectomy for RCC were reviewed. Comparison was made between radiologic analysis and pathologic findings regarding involvement of the adrenal gland. Results. The size of the renal tumor varied between 3.5 and 19 cm (mean 8.5). The upper pole was involved in 45%, the lower pole in 28%, and the midpole in 18% of the patients, and in 9% the whole kidney was involved by the tumor. Histologic findings showed that 72 (94%) of the 77 adrenal glands were normal and 70 of these were normal on CT as well. Two adrenal glands involved by metastases showed heterogeneous contrast entrancement on CT. The benign lesions of three adrenal glands were also picked up as abnormal on CT. In 2 patients adrenal glands could not be visualized on CT because of a paucity of retroperitoneal fat. Conclusions. Adrenalectomy with nephrectomy may not be performed in patients with RCC in whom CT demonstrates normal adrenal glands. In patients with adrenal abnormality on CT, magnetic resonance imaging can separate metastases from incidental benign adrenal adenoma, further reducing the number of patients requiring removal of the adrenal gland.

We previously reported on a group of patients with post-circumcision carcinoma of the penis. We now study the long-term outcome of these patients.We retrospectively reviewed the available charts of 22 patients presenting between October 1979 and May 2000.Of 22 patients 18 underwent ritual circumcision with extensive scar development. Median age at diagnosis was 62.4 years. The penile lesion was dorsal and proximally located in 15 patients. Median delay before diagnosis was 12 months. Clinically 14 patients had stage T1-T2 disease, with 13 having no lymph node involvement and none with distant metastasis, 8 patients had stage T3-T4 disease. A total of 15 patients were treated surgically with total penectomy (10) or conservative local excision (5), inguinal lymph node dissection (9) and subsequent penile reconstruction (3). Pathological staging in 15 patients revealed 10 patients with stage T1 and in 8 patients with lymph node dissection none had nodal metastasis. Histopathological classification was 20 squamous cell carcinoma, 1 sarcoma and 1 verrucous carcinoma. Six patients refused surgery and 1 was referred for palliation. Median followup was 14.5 months and median survival was 14.5 months. The 3-year survival was 42% for stage T1-T2 and 13% for T3-T4 (p = 0.0052). Median survival for the surgical group was 34 months whereas for nonsurgical group was 3 months (p = 0.0016). Recurrence-free survival in the surgical group was 50%.Penile carcinoma in circumcised men is a distinct disease commonly following nonclassic vigorous circumcision. Delayed diagnosis and deferring surgical treatment are associated with increased mortality.

Between January 1977 and June 1985, 63 patients requiring supravesical diversion underwent ureterosigmoidostomy with an antireflux technique. Of the patients 49 had bladder cancer and 14 had other conditions. Two patients died in the postoperative period. Postoperatively, all patients were instructed to empty the rectum frequently, and received bicarbonate and potassium supplementation.Median followup was 41 months (range 3 to 70). Renal function remained stable in 92 percent of the patients. Radiographic deterioration occurred in 23 percent of the renal units, which was severe in 7 percent. These results indicate that the short and intermediate followup results with ureterosigmoidostomy are comparable to those of an ileal conduit. The method has the added advantage of being a form of continent diversion. We believe that ureterosigmoidostomy remains a viable and convenient alternative in select patients with bladder cancer who are not suitable for other forms of continent diversion or bladder subs...

Invasive squamous cell carcinoma of the penis occurs on the glans, prepuce, glans and prepuce, coronal sulcus and shaft. Penile squamous cell carcinoma subsequently invades local structures, corpora cavernosa and the urethra, and metastasizes to the inguinal lymph nodes. Invasive squamous cell carcinoma of the penis usually requires total or partial penectomy. We studied the effect of primary tumor resections tailored to the anatomical extent of the cancer with preservation of uninvolved structures in select patients with invasive penile squamous cell carcinoma.A total of 30 patients between 39 and 82 years old were treated with unconventional conservative surgical excision of the primary penile lesion. More than 130 patients were excluded from the study because they were treated with partial or total penectomy, Mohs' surgery or more extensive surgery. The 30 patients underwent preoperative biopsy with careful mapping of the extent of the disease. Patient age, tumor extent and grade, operative details, outcome and length of followup were analyzed.Tumor size ranged from 1.5 to 8 cm. in diameter. Tumors were well differentiated in 19 patients, moderately differentiated in 5 and poorly differentiated in 6. A total of 17 patients underwent ilioinguinal lymphadenectomy, 12 of whom had pathologically positive lymph nodes. Inguinal radiation was used in 2 patients. Chemotherapy was given to 7 patients with extensive inguinal lymphadenopathy and to 2 of 5 with pathologically positive lymph nodes. Followup ranged from 12 to 360 months. A total of 21 patients had no evidence of disease at last followup. Tumor resection with no sacrifice of function was performed in 2 patients in whom 3 small recurrences developed. One patient with numerous tumors had 2 small recurrences, which were completely excised with no further recurrence. Of the 7 patients with advanced lymphadenopathy 5 and of 5 patients with pathologically positive lymph nodes at presentation 1 died of the cancer but had no local recurrence in the penis.In a minority of patients with anatomically suitable penile cancer conservative surgical techniques are safe and provide equal tumor control compared to conventional resections. The anatomical situation and tumor characteristics should dictate the choice of treatment for the primary penile lesion. Inguinal lymph nodes should be managed by appropriately established guidelines but should not influence the extent of primary penile lesion resection.

We describe our experience with a surgical technique using the multiple fire Endo-GIA-30-3.5 stapler to control the vascular pedicles during radical cystectomy. This technique was performed in 16 radical cystectomies, including three pelvic anterior exenterations for female invasive bladder carcinoma, and compared with 23 cases treated with the conventional method. It was associated with a significant decrease in the intraoperative and postoperative blood loss and a shorter operative time.

Sixty female patients with acquired urinary fistulas are reviewed. These include ureterovaginal, urethrovaginal, vesicovaginal, and vesicouterine fistulas; many patients had more than one ...

Urinary calcium excretion was measured in 100 consecutive normocalcemic patients with calcium urolithiasis and 12 Saudi Arabian controls while the patients and the controls were eating their usual diet of unknown calcium content. Only 16 patients were hypercalciuric using the definition of twenty-four-hour urinary calcium of more than 300 mg for males and more than 250 mg for females, and one of these patients was subsequently found to have hyperparathyroidism. The twenty-four-hour urine calcium was less than 200 mg in 60 per cent of male patients and in all the male controls. Since the dietary intake of calcium during the twenty-four-hour urinary collection was unknown, a 1,000-mg calcium loading test was performed in an attempt to differentiate various patterns of abnormal calcium excretion. Of the twenty-four-hour normocalciuric patients 10 (18%) had "absorptive hypercalciuria" and 16 patients (29%) demonstrated a "renal hypercalciuria" pattern. Thirty-nine patients (57%) and all 12 controls had normocalciuria before and after calcium loading.

The first case is reported of several common and rare late complications of an ileal conduit in a child, including a conduit-cecal fistula. The initial and final surgical management, including undiversion, is described.

A case is reported of a twenty-two-year-old man who had sustained partial amputation of the penis at circumcision. This had resulted in a scarred and deformed micropenis with sexual inadequacy. A method of successful plastic penile reconstruction using split thickness skin graft is illustrated.

The findings are described in 2 children with obstructive urethral diverticula. The causation, presentation, diagnosis, and management are discussed.

Five Saudi Arabian children, 2 to 6 years of age, presented with far advanced Wilms' tumors impairing staging and treatment according to the recommendations of the American National Wilms'...

A 36-year-old Saudi underwent a total penectomy for cancer involving the penile shaft with no corporeal invasion or distant metastases. One year postoperatively and in the absence of tumor recurrence or metastasis, a penile reconstruction using a right myocutaneous gracilis flap was performed. The result two years later was satisfactory, with preservation of deep penile sensation and successful weekly sexual intercourse. To our knowledge, no similar case has been reported previously.

Definite progress has been made in the treatment of bilateral Wilms' tumors with marked improvement in the prognosis. This is confirmed in our series of 6 consecutive patients with synchronous tumors. The recent trend toward more conservative surgery, double or triple drug chemotherapy, and avoidance of high-dose radiation therapy has yielded good results.

The role of ultrasonography, computed tomography (CT), and radioisotopic scanning in the staging of bilharzial bladder cancer has not been reported previously. Forty patients with invasive bladder cancer seen at the King Faisal Specialist Hospital and Research Centre between January 1978 and June 1981 underwent complete preoperative workup for staging of their tumors prior to radical cystectomy. The preoperative radiologic investigations included excretory urography (IVP), ultrasonography (US), CT of the pelvis, and liver and bone scans. The results of these investigations were compared with the operative and pathologic staging. Ninety-three percent of the patients with bilharzial cancer had evidence of ureteric obstruction on IVP compared with 22% of the nonbilharzial cancer patients. The presence of ureteric obstruction in these patients did not correlate with the stage of the disease with 83% of the patients with superficial tumors (T1 and T2) having hydroureteronephrosis. Ultrasonography and CT had an 83% accuracy in the staging of superficial tumors. Stage T3 tumors were understaged in 14% of the cases. Ultrasonography did not differentiate Stages T3 and T4 tumors while CT scan differentiated these two stages in 57% of the cases. Bone scan failed to reveal evidence of metastatic disease in any of the bilharzial cancer patients. Liver scan was suspicious for liver metastases in two patients with bilharzial cancers in whom open liver biopsy revealed only hepatic bilharziasis. Of all the radiographic studies, US or preferably CT scan seem to be of some value in the staging of bilharzial tumors localized to the bladder. Bone and liver scans are probably of no cost effective benefit.
