[Percutaneous endourologic treatment of obstructive ureteral lithiasis in renal transplant].

Donor graft lithiasis is a unusual complication of renal transplantation, however, it is associated to a high morbidity. This pathology is due to several causes such us: metabolic factors, infectious disease, drugs, foreign bodies or transferred in the donor graft. The objective of the treatment is to remove the lithiasis without damaging the renal unit. We report the successful percutaneous anterograde treatment of an ureteral obstructive hard calculi, in renal allograft.

[Clinical pathway for TUR of bladder neoplasms. Analysis of the first 2 years of its implementation].

OBJECTIVE: To analyze the results of the first two years of application of the clinical pathway for transurethral resection (TUR) of bladder tumors at La Paz University Hospital. METHODS: We developed a clinical pathway of 4 hospital stays (5 days) for TUR of the bladder that included the following: matrix-verification, treatments prescribed, verification of changes, patient information sheet and patient satisfaction questionnaire. The information for the evaluation of the results were obtained from the pathway records and data on the activities of the Urology services. To assess the results for efficiency in the use of resources, the mean duration of hospital stay of patients in the pathway were compared with that of a control group comprised of 50 randomly selected patients submitted to TUR of the bladder in 1997. RESULTS: From June 1998 to May 2000, 481 of the 494 (97.4%) treated patients entered the clinical pathway. CONCLUSIONS: In our experience, the clinical pathway for the urinary bladder is a useful instrument for developing the clinical management of this condition. It reduces the unwanted changes in patient care and hospital stay, carries a low incidence of complications and readmissions, and achieves a high degree of patient satisfaction.

[Giant chondroid syringoma of the scrotum. First reported case].

OBJECTIVE: Various tumors have been described in the scrotal area arising from skin and the underlying tissues: nevus, dermoid and epidermoid cysts, epidermoid carcinomas, lipomas, leiomyomas, angiokeratomas, lymphangiomas, granular cell tumors, granuloma, malignant tumors of the peripheral nerve tissue, and some 'pseudotumors' such as fibromatosis and nodular calcinosis. We describe for the first time a sweat gland tumor, which is also remarkable for its unusually large size. METHODS/RESULTS: A 76-year-old patient consulted for a painful left scrotal tumor that he had noted for some time and that had slowly and gradually grown. Ultrasound assessment of the GU system confirmed the presence of a 4.2 cm left, solid paratesticular mass that was removed under local anesthesia. CONCLUSIONS: Chondroid syringoma is a tumor arising from the sweat gland that is usually localized to the head and neck. It has an excellent prognosis and recurrence has only been described in patients in whom the tumor had not been completely resected.

[Treatment of erectile dysfunction with vacuum devices].

OBJECTIVE: To analyze the results achieved with vacuum devices in the treatment of erectile dysfunction. METHODS: A telephone survey was conducted on 150 patients undergoing treatment with a vacuum device. Of these, 89 responded; 79 of which were considered valid for the study. The duration and frequency of use, side effects and degree of patient and partner satisfaction were analyzed. Mean follow-up was 59.5 months. RESULTS: There were 14 dropouts early in the course of treatment. The remaining 65 patients used the device for a mean duration of 34.6 months, 3.7 times monthly. 63.3% of the patients achieved erection in more than half of the attempts. The most frequent side effects were pain (27 patients) and ecchymosis (7 patients). Forty-eight patients discontinued treatment at 10.8 months' mean follow-up. The most common causes for discontinuing treatment were lack of efficacy, refusal of the partner and pain. CONCLUSIONS: Treatment of erectile dysfunction with the vacuum constriction device should be utilized as an alternative to intracavernosal drug-induced erection therapy when oral therapy fails or is contraindicated. A male with a stable partner and impotence arising from venous leakage or mild cavernous artery insufficiency is the ideal candidate.

[Bladder leiomyoma during pregnancy].

OBJECTIVE: To describe an additional case of rapidly growing leiomyoma of the bladder in a pregnant woman. METHODS: A case of leiomyoma of the bladder in a woman at 8 months of pregnancy is presented. Transurethral resection was performed, but the tumor recurred a few weeks later. The tumor was resected by partial cystectomy after delivery. CONCLUSIONS: Leiomyoma of the bladder is an uncommon benign lesion that is successfully managed by surgical resection. The rapid recurrence of the tumor in our patient can be ascribed to the hormonal changes during pregnancy.

[Development of a clinical pathway for radical prostatectomy].

OBJECTIVE: To describe the clinical care path for retropubic radical prostatectomy of the La Paz teaching hospital and the results achieved after the first 6 months. METHODS: We have developed a clinical care path for radical prostatectomy with a hospital stay of 6 days. Thirty-one patients submitted to retropubic radical prostatectomy from June to November 1998 were included in the program. The mean length of total, preoperative and postoperative stay were analyzed and compared with those of 31 patients who had undergone radical prostatectomy before the program was developed. Readmissions, adverse effects and patient satisfaction were also analyzed. RESULTS: Of the 31 patients included in the clinical care path, 22 (71%) had a stay equal to or less than the program's length of stay. The mean total, pre and postoperative stay for the group of patients included in the clinical care path were 6.0 days (SD = 1.1), 1 day (SD = 0.0) and 4.9 days (SD = 1.1), respectively. The length of stay was significantly longer before the program was developed [mean total 10.2 days (SD = 4.9), mean preoperative 2.6 days (SD = 2.6) and mean postoperative 7.6 days (SD = 3.6)] (p < 0.001). Twenty-four patients (77.4%) completed the questionnaire on patient satisfaction, which was highly positive, the overall patient satisfaction rate being higher than the 90% standard. There were no readmissions or significant events ascribable to the program. CONCLUSIONS: In our experience, the clinical care path for radical prostatectomy is a useful tool to reduce the unwanted variability. Its design is based on the best possible evidence, therefore the scientific and technical quality, patient satisfaction and efficiency are enhanced. In our view, our results are attainable and feasible in any health care setting.

[Recurrent nonparasitic chyluria].

OBJECTIVE: To describe a case of recurrent chyluria and review the diagnostic and therapeutic methods. METHODS/RESULTS: A case of non parasitic recurrent chyluria is presented. Retrograde pyelography demonstrated pyelolymphatic reflux. The patient presented chemical pyelitis secondary to the contrast medium which caused remission of the condition. CONCLUSIONS: Chyluria is uncommon in our setting. Postprandial cystoscopy permits identification of the compromised renoureteral unit and perform pyelic instillation of sclerosing agents. Surgery should be reserved for those cases in whom conservative management has failed.

[Granulomatous prostatitis. Analysis of 15 cases and review of the literature].

OBJECTIVES: The present study describes our experience with granulomatous prostatitis, an uncommon disease entity, with special reference to the etiological factors and the clinical and pathological features. METHODS: 15 cases of granulomatous prostatitis seen at our department over a 2-year period were retrospectively analyzed. RESULTS: The most frequent etiological factor was surgery (TUR) or prostatic needle biopsy (53%). Prostate cancer was suspected in 8 patients based on the findings of DRE. CONCLUSIONS: The diagnosis of granulomatous prostatitis is based on the histological findings. Despite its low incidence, it is currently diagnosed more frequently due to the increase in TURP and prostatic biopsy procedures and the widespread use of intravesical BCG therapy for some superficial bladder tumors.

[Use of intrarectal lidocaine gel in ultrasound-guided transrectal biopsies of the prostate].

OBJECTIVE: To know in a quantitative manner the degree of discomfort and pain of the biopsies of the prostate and to evaluate the effectiveness of the transrectal lidocaine. MATERIAL AND METHOD: We performed 140 transrectal biopsies of the prostate, Patients were included on a random basis into two arms: one of them received intrarectal lidocaine, 20 mg (group 1, n = 71) and the other group received placebo (group 2, n = 28) both of them ten minutes prior the proceeding. RESULTS: The global pain mean was 3.7 (0 no pain, 10 highest pain) and the global discomfort mean was 3.5. The group 1 patients showed a trend to feel less pain and discomfort although it did not reach the necessary statistic significance (p = 0.7 y p = 0.5 respectively). CONCLUSIONS: We do not achieve the good results obtained by other groups in order to decrease the degree of pain and discomfort with the use of intrarectal lidocaine. We did not find relationship between the PSA level, previous biopsies, intrarectal lidocaina and degree of information received and the degree of pain and discomfort.

[Prognostic value of inverted papilloma of the lower urinary tract].

OBJECTIVE: Inverted papilloma of the urothelium accounts for 2.2% of urothelial neoplasms. Its oncologic significance is unclear; its potential for recurrence and/or progression is not well-known. Our experience from 1976 to 1999 is reviewed. METHODS: From 1976 to 1999, 31 patients with urothelial inverted papilloma of the lower urinary tract have been treated in our service: 17 presented previous and/or synchronous association with urothelial carcinoma (group I) and 14 had primary inverted papilloma (group II). The recurrence and progression rates for each group were determined and compared. The overall recurrence and progression rates were also determined. Two patients (one from each group) were lost to follow-up. The remaining 29 patients had a mean follow-up of 51.3 months (range 3-125). RESULTS: 12 patients (41.4%) showed recurrence in the form of bladder carcinoma; 10 from group I (10/16; 62.3%) and 2 from group II (2/13; 15.4%) (p < 0.05). Mean time to recurrence was 17.9 months (range 3-58). Disease free interval was higher in group II (p < 0.05). Progression to infiltrating tumor was observed in three patients; all three had associated superficial bladder carcinoma (group I). The mean time to progression was 30.7 months (range 18-38). No statistically significant differences were found in the percentage of progression between both groups. CONCLUSIONS: Inverted papilloma of the lower urinary tract showed a high incidence of association with urothelial carcinoma and a high recurrence rate, even in primary tumors. Therefore it should be considered a tumor of low grade malignancy that should be followed regularly.
