Role of penile vascular insufficiency in erectile dysfunction in renal transplant recipients.

The objectives of this study were to define the role and haemodynamic features of penile vascular insufficiency in impotent renal transplant recipients (RTR) as well as to establish the possible vascular risk factors for impotence in these patients. A total of 54 RTR (35 impotent and 19 potent) and 21 potent healthy subjects were included in this study. All patients were assessed clinically and by measurement of serum creatinine, serum bilirubin, cyclosporine blood levels, haemoglobin and total serum cholesterol. All subjects were subjected to intracavernous injection of 20 microg prostaglandin E1 followed by colour Duplex sonographic examination. Our results showed that impotent RTR were significantly more likely than potent RTR to have hypertension, diabetes and hypercholesterolaemia (P<0.05). Arterial occlusive disease was identified in 42.9% of impotent RTR. Findings suggestive of veno-occlusive dysfunction were found in 68.6% and 26.3% of impotent and potent RTR, respectively (P=0.003). Unilateral ligation of the internal iliac artery has a negative role on haemodynamic parameters compared to unilateral end-to-side anastomosis to external iliac artery in impotent RTR (P<0.05). Impotent RTR receiving more than one antihypertensive drug showed significant decrease in basal peak systolic velocity (PSV), dynamic PSV, erectile angle and cavernosal artery diameter compared to those receiving one drug (P<0.05). In conclusion, penile vascular insufficiency appears to play a substantial role in the pathogenesis of impotence in transplant patients. Anastomosis of the graft to external iliac artery could preserve the potency to some degree. Antihypertensives should be reduced as much as possible to avoid their negative effects on erectile function.

Rapid diagnosis of genitourinary tuberculosis by polymerase chain reaction and non-radioactive DNA hybridization.

OBJECTIVE: To establish a polymerase chain reaction (PCR) assay for the rapid detection and identification of mycobacteria in urine, and to assess the value of such assay in routine laboratory diagnosis of genitourinary tuberculosis. MATERIALS AND METHODS: Urine specimens from 1000 patients with clinical suspicion of urinary tuberculosis were examined. Two assays for the detection and identification of Mycobacterium tuberculosis (M. tuberculosis) complex and mycobacteria other than tuberculosis (MOTT) by non-radioactive DNA hybridization of PCR-product were applied. The first assay used PCR primers and probe derived from M. tuberculosis species-specific DNA insertion sequence, IS6110. The second utilized mycobacterium genus-specific sequence encoding ribosomal ribonucleic acid (16S rRNA). The results obtained by PCR were compared with those obtained by standard microbiological methods, acid-fast bacilli (AFB) stain and culture. RESULTS: Compared with cultures, the sensitivity of AFB staining was 52.07% and the specificity was 96.7%. In comparison to the results of culture, the overall sensitivity and specificity of the IS6110-PCR assay was 95.59% and 98.12% respectively. While the corresponding results for the 16S rRNA gene-PCR were 87.05% and 98. 9%. CONCLUSION: The high sensitivity and specificity in addition to the potential for rapid detection of mycobacteria, makes this test a useful tool in the clinical management of mycobacterial infection in urine. Urine specimens may contain M. tuberculosis and/or other mycobacteria; therefore, there are advantages in using genus-specific primers in parallel with species-specific primers in PCR assay.

Human ochratoxicosis and nephropathy in Egypt: a preliminary study.

This preliminary study was designed in a trial to delineate the size of the problem of ochratoxicosis and its relation to genesis of lesions mounting to end stage renal disease (ESRD) or urothelial tumors in Egypt. This study comprised five groups of patients having renal diseases of different presentations; they are: patients with (ESRD) under conservative medical treatment (group 1), patients with (ESRD) under treatment with regular hemodialysis (group 2), renal allograft recipients (group 3), patients with nephrotic syndrome (group 4) and patients with urothelial tumors (group 5). In addition, two reference groups: potential related donors for renal transplantation (group 6) and healthy control with negative family history of renal disease (group 7). For all groups, laboratory, radiological and histopathological evaluation of kidney status were carried out coupled with determination of ochratoxin A level in serum, in urine and in biopsy specimens of patients with urothelial tumors. High ochratoxin serum levels were found in patients with ESRD (groups 1 and 2) (P < 0.01), higher serum levels were detected in the group without dialysis (group 1) in comparison with the reference groups possibly due to ochratoxin. A clearance by dialysis. Ochratoxin A was detected in serum and urine of renal transplant recipients (group 3) (P < 0.01) and especially higher levels were found in patients with nephrotic syndrome (group 4) (P < 0.001). For the group with urothelial tumor (group 5), positive serum, urine and tissue biopsy specimens for ochratoxin levels were found (P < 0.01). The results could lead to the conclusion that ochratoxin A could be correlated to the genesis of renal disease leading to (ESRD) or causing urothelial cancer. A thorough and in depth study of the problem of ochratoxicosis and renal disease causation in Egypt is now recommended.

Laparoscopic nephrectomy: Mansoura experience with 106 cases.

OBJECTIVE: To describe the technique and report our experience of laparoscopic nephrectomy. PATIENTS AND METHODS: Between August 1992 and December 1993, 106 patients underwent laparoscopic nephrectomy at the Mansoura Urology and Nephrology Center. RESULTS: Of the 106 patients, laparoscopic nephrectomy was performed successfully in 97 cases. Conversion to an open procedure was necessary in the remaining nine patients. CONCLUSION: For a selected group of patients, laparoscopic nephrectomy is a feasible and safe technique. The length of hospital stay and convalescence is short and return to work is rapid.

Accidental division of the transplanted ureter during laparoscopic drainage of lymphocele.

We report on the accidental division of the ureter of a transplanted kidney during laparoscopic marsupialization of a symptomatic lymphocele into the peritoneal cavity. Identification of the lymphocele was difficult because of a thick layer of overlying periperitoneal fibrolipomatous tissue. The complication was identified intraoperatively and stented reanastomosis of the divided ureter was performed. Postoperative course was uneventful. To avoid accidental injury to the transplanted ureter during laparoscopic drainage of lymphocele, we recommend that a ureteral catheter be inserted.

Tetracycline sclerotherapy for testicular hydroceles in renal transplant recipients.

OBJECTIVES: To study the efficacy of tetracycline sclerotherapy in renal transplant recipients with symptomatic hydroceles. METHODS: A total of 21 patients with symptomatic hydroceles following renal transplantation underwent aspiration of hydrocele and injection of tetracycline hydrochloride. Sclerosant solution was prepared by dissolving 1 g tetracycline hydrochloride powder in 10 mL 1% lidocaine. The amount of sclerosant used depended on the volume of the sac: 5 mL for a sac containing up to 100 mL and 2.5 mL of sclerosant was added for each increase of 100 mL in sac volume. RESULTS: Twelve patients (57%) required only one treatment and 9 patients (43%) had up to 3 injections. The larger the hydrocele, the more treatments were required. The resolution of hydrocele was complete in 12 patients (57%) and partial in 7 (33%) with 2 (10%) failures. Pain at injection was observed in one third of the patients. No major complications (fever, hematoma, infections, abscess, or scrotal necrosis) occurred in any patient. No changes in the structure or size of the testicles were found by ultrasound during an average follow-up period of 35 months. CONCLUSIONS: Tetracycline sclerotherapy is a safe, effective, and economical form of out-patient therapy that can be recommended as primary treatment for hydroceles in patients who have undergone renal transplantation.

Laparoscopic nephrectomy: an established routine procedure.

Between August 1992 and April 1993, 60 patients underwent laparoscopic nephrectomy in our institution for benign disease (35 hydronephrosis, 20 chronic pyelonephritis, 4 end-stage kidney, 1 renal hypoplasia). Conversion to open surgery was needed in six cases to overcome intraoperative bleeding or perirenal adhesions. The mean operative time was 3.5 +/- 1.3 hours, and the mean hospital stay was 3.2 +/- 2.1 days. No deaths occurred, but significant complications were encountered in four cases in the form of pulmonary embolism, a large hematoma, postoperative bleeding, and colonic perforation. Laparoscopic nephrectomy is a safe and effective alternative to open nephrectomy for benign renal conditions.
