Gluteal Necrosis and Lumbosacral Plexopathy in a Diabetic Patient after Renal Transplantation.

A 34-year-old diabetic patient underwent a renal transplant which was complicated by right side lower extremity paresis and numbness with gluteal necrosis. The main reason was ligation of internal iliac artery of the same side as a result of extensive microvascular obstruction due to severe atheromatous plaque. This is a rare complication which is mostly reported in aneurysmal patients after bypass surgery. The gluteal necrosis is a serious complication which, as in our patient, resulted in patient's death in most of the reported cases. Because of catastrophic nature of this condition, identifying preventive measures is extremely important.

Quality of life after radical cystectomy for bladder cancer in men with an ileal conduit or continent urinary diversion: A comparative study.

AIM: To investigate quality of life (QoL) domains with three forms of urinary diversions, including ileal conduit, MAINZ pouch, and orthotopic ileal neobladder after radical cystectomy in men with muscle-invasive bladder cancer. MATERIALS AND METHODS: In a prospective study, 149 men underwent radical cystectomy and urinary diversion (70 ileal conduit, 16 MAINZ pouch, and 63 orthotopic ileal neobladder). Different domains of QoL, including general and physical conditions, psychological status, social status, sexual life, diversion-related symptoms, and satisfaction with the treatment were assessed using an author constructed questionnaire. Assessment was performed at three months postoperatively. RESULTS: In questions addressing psychological status, social status, and sexual life, patients with continent diversion had a more favorable outcome (P = 0.002, P = 0.01, and P = 0.002, respectively). The rate of erectile dysfunction did not differ significantly between the three groups (P = 0.21). The rate and global satisfaction was higher with the MAINZ pouch (68.7%) and ileal neobladder (76.2%) as compared with the ileal conduit group (52.8%) (P = 0.002). CONCLUSION: Continent urinary diversion after radical cystectomy provides better results in terms of QoL as compared with ileal conduit diversion.

Sexual function after non-nerve-sparing radical cystoprostatectomy: a comparison between ileal conduit urinary diversion and orthotopic ileal neobladder substitution.

OBJECTIVE: To compare the erectile function (EF) and sexual desire (SD) in men after radical cystoprostatectomy (RCP) who had either an ileal conduit urinary diversion or orthotropic ileal neobladder substitution. MATERIALS AND METHODS: Eighty one sexually active men with bladder cancer were enrolled in this prospective study. After RCP according to patients' preferences they underwent either ileal conduit urinary diversion (n = 41) or orthotropic ileal neobladder substitution (n = 40). EF and SD were assessed using International Index of Erectile Function (IIEF) questionnaire. Patients were assessed at 4-week before surgery and were followed up at 1, 6, and 12-month postoperatively using the same questionnaire. RESULTS: Postoperatively the EF and SD domains deteriorated significantly in both groups, but in a small proportion of the patients submitted to ileal neobladder they gradually improved with time (P = 0.006). At 12-month postoperative period, 4 (9.8 %) and 14 (35.0 %) patients in ileal conduit and ileal neobladder groups were able to achieve erections hard enough for vaginal penetration and maintained their erection to completion of intercourse, respectively (P = 0.006). Among patients in the ileal conduit and ileal neobladder groups, additional 4 (9.8 %) and 7 (17.1 %) patients were able to get some erection, but were unable to maintain their erection to completion of intercourse (P = 0.02). At 12-month follow up period 24.4 % of the ileal conduit and 45.0 % of the ileal neobladder patients rated their sexual desire very high or high (P = 0.01). CONCLUSION: When performed properly, orthotopic ileal neobladder substitution after RCP offers better long-term results in terms of EF and SD.

Atorvastatin improves the response to sildenafil in hypercholesterolemic men with erectile dysfunction not initially responsive to sildenafil.

Despite the initial enthusiasm, the significant number of patients in whom sildenafil is contraindicated or ineffective is a major challenge to all urologists. Our aim was to determine the safety and efficacy of adjunctive atorvastatin in restoring normal erectile function in hypercholesterolemic (low-density lipoprotein (LDL) cholesterol >120 mg per 100 ml) sildenafil nonresponders. The study comprised 131 men with ED not responding to sildenafil citrate. They were randomized either to 40 mg atorvastatin daily (n=66, group 1) or matching placebo (n=65, group 2) for 12 weeks while they were taking on-demand 100 mg sildenafil. Erectile function was subjectively assessed using the 5-item version of the International Index of Erectile Function (IIEF-5) questionnaire and response to the global efficacy question (GEQ). Serum biochemical and lipid profile (total cholesterol, triglycerides, LDL cholesterol and high-density lipoprotein cholesterol) analyses were performed at baseline and repeated at post-treatment weeks 6 and 12. Compared with the placebo group (59 patients, mean age+/-s.d. 61.9+/-6.1, mean years ED 3.9+/-1.8), the atorvastatin group (59 patients, mean age+/-s.d. 63.9+/-6.9, mean years ED 3.7+/-1.6) had significantly greater improvements in all IIEF-5 questions (P=0.01) and GEQ (P=0.001). Subgroup analyses did reveal trends in the atorvastatin group to indicate that a change in the IIEF-5 score is affected by age, severity of ED and baseline serum levels of LDL. Patients with moderate (r=0.28, P=0.01) and severe (r=0.20, P=0.01) ED had better positive response rates to adjunctive atorvastatin than patients with mild to moderate ED. None of the patients taking atorvastatin achieved a response of 5 to the IIEF-5 questions and none of the patients regained normal erectile function as defined by the IIEF-5 score >21. Subjects experienced a statistically significant but modest improvement in erectile function. Further investigation is needed to test the usefulness of long-term atorvastatin administration to restore erectile function in sildenafil nonresponders.

Extracorporeal shock wave lithotripsy of renal calculi during early pregnancy.

OBJECTIVE: To evaluate the safety of renal stone treatment by extracorporeal shock wave lithotripsy (ESWL) during pregnancy. PATIENTS AND METHODS: Data from 824 women of reproductive age who were treated by ESWL were analysed and the patients surveyed using a questionnaire about pregnancies, to which 636 (76%) responded. Of these patients, six had inadvertently undergone ESWL for renal stones during the first month of pregnancy. The stones were detected and located during ESWL using ultrasonography. RESULTS: The six patients gave birth to six children who had no detectable malformations or chromosomal anomalies. CONCLUSION: Although these results suggest that there were no adverse effects of ESWL during early pregnancy, a larger series should be assessed to confirm the safety and long-term effects of ultrasound-guided ESWL in the treatment of renal calculi during pregnancy. We do not advocate lithotripsy as a treatment for renal calculi in pregnancy, but inadvertent lithotripsy in a pregnant woman is not a cause for concern.

Accuracy of residual urine measurement in men: comparison between real-time ultrasonography and catheterization.

PURPOSE: The practical value of ultrasonography as a rapid means to determine accurately residual urine volume was assessed. MATERIALS AND METHODS: Transverse and sagittal bladder diameters, as well as areas from longitudinal and transverse images, were measured with real-time ultrasonography in 324 men immediately after voiding. Calculated bladder volumes using measured diameters and areas for each of 11 formulas in the literature were compared to the corresponding measured total residual urine volumes. RESULTS: The lower limit of ultrasonographic visualization of urine in the bladder was approximately 48 ml. No correlation existed between ultrasound calculated bladder volumes and measured residual urine for any of the 11 formulas. CONCLUSIONS: Ultrasonography cannot rapidly measure bladder volumes accurately to date. Catheterization remains the most accurate method of assessing post-void residuals but in many cases it may not be the best approach to patient care.

Penile fractures: evaluation, therapeutic approaches and long-term results.

PURPOSE: Traumatic rupture of the corpus cavernosum of the penis is rare and has been reported infrequently. We demonstrated the moderate frequency and most common etiologies of this condition. MATERIALS AND METHODS: Between February 1990 and June 1993, 68 patients underwent an emergency operation 3 hours to 4 days after penile fracture. RESULTS: Among 32 patients who completed a questionnaire functional results were excellent except for 3 with penile curvature and pain during coitus who underwent surgery more than 48 hours after injury. CONCLUSIONS: Fracture of the penis is a common urological problem. In our series the most common cause was manipulation. To avoid serious complications immediate surgical intervention is recommended.
