Abstract

Background and Objective: Computerized tomographic angiography (CTA) is a minimally invasive modality to image the vasculature without the morbidity of direct large vessel vasculature access and its major indications in urology are assessment of the renal vasculature in preparation for donor nephrectomy, identification of extravessel in evaluation of ureteropelvic junction obstruction and for diagnosis of renal artery stenosion. This study was done to evaluate vescels of kidney donors using CTA and formal angiography and comparison with intraoperative findings. Materials and Methods: In this descriptive study, kidney vessels of 70 and 30 living kidney donor were assessed with computerized tomographic angiography and formal angiography respectively. The pattern of vessels of kidney during operation were examined. Two observers assessed the findings of preoperative CTA and formal angiography with intra operation observations. Results: In CTA group there were two patients each with two main renal veins which were observed during operation was not recorded on computerized tomographic angiography. In formal angiography group there was one patient with unrevealed two main renal veins prior to surgery. In both groups, the accuracy of anatomical diagnosis of the main kidney artery were 100%. Conclusion: This study showed that kidney vascular assessment by either the computed tomography angiography or formal angiography have similar clinical diagnostic accuracy.

Abstract

Background and Objective: Lower ureter is the most common site of stone traped causing renal colic and hydroureteronephrosis. If medical therapy is not effective , the treatment consist of extracorporeal shock wave lithotripsy (ESWL), transurethral lithotripsy (TUL) or on rare cases, open surgery. This study was done to compare the ESWL with TUL in sixty patients with lower ureteral stones which did not responed to thraputic regiment. Materials and Methods: This prospective cohort study was done on sixty patients with obstructive lower ureteral stones for more than 3 weeks, that have not been responded to the thraputic regiment in Imam Reza hospital, Mashhad, Iran during 2004-06. According to treatment indications sixty patients divided in two equal ESWL and TUL groups. Success of procedure were evaluated by ultrasonography and KUB radiography. The success rate of two different technique and the side effects in each patients was recorded. Results: In ESWL group in 14 patients (46.66%) the stone was broken and its particles were removed but in 13 patients (43.33%) the stone was not broken and they became candidates for TUL. In 3 patients (10%) the stone was broken but the particles did not pass. The only complication of ESWL was renal colic which was in 15 patients (50%) and cured by medical treatment. In TUL group, in 93.5% of patients, the stone was broken and particles were removed, but in 6.5% the procedure was not successful and the patients underwented ESWL or open surgery. 10% of patients experienced fever and colic pain, who underwented medical treatment. Conclusion: This study showed that TUL technique has higher successful rate than ESWL technique in lower uretaral stones.

Abstract

Buschke–Lowenstein Tumor (BLT) or Giant Condyloma Acuminatum (GCA) is a slow-growing, locally aggressive, cauliflower-like tumor of great size that usually arises in the perineal region. Buschke–Lowenstein Tumor is triggered by human papilloma virus (HPV), usually either genotype 6 or 11. Buschke–Lowenstein Tumor is usually preceded by condyloma acuminatum and occurs at any age after puberty, usually between the 4th and 6th decades. Invasive overgrowth and recurrence after treatment are its characteristics and malignant transformation is also possible. Here, we have reported a case of a 33 year-old man with penile Buschke–Lowenstein Tumor arising from common genital warts.

Abstract

Background and Objective: Intercostal and supracostal access tract are usual access for percoutaneous nephrolithotripsy (PCNL) for upper calices stones. But pleural complication of these tracts are high. This study was done to evalute percutaneous nephrolithotomy (PCNL) of upper calices with subcostal access. Materials and Methods: Seventeen patients (12 males, 5 females) with stones limited to upper calices with diameters of 11-27 mm and 1-5 in numbers, candidated for PCNL. Ultrasonography and intravenous urography were performed for all patients prior to surgery. In all patients PCNL performed in prone position and access is made at prolonged and deep inspiration from subcostal with fluoroscopic guidance. Following access to upper calices, guide wire inserted and dilatation of tract up to 28 or 30 Fr informed. After insertion of 28 or 30 Fr Amplatz sheat nephroscopy performed. Results: Two patients excluded and finally 15 patients were accounted. In 15 patients subcostal access performed successfully (88.2 %) . In 5 patients stones of less than 10 mm extracted with grasps. In 10 patients after pneumatic lithotripsy, particles of tones removed. 11 patients rendered stone free (73.3%). 4 patients had residual stones of greater that 5 mm in minor calices that in 3 patients after single ESWL resolved. 3 patients needed infandibular dilatation for complete stone extraction. No infection, transfusion, pneumothorax, hydrothorax, respiratory discomfort in operation and post operation period were seen. In one patient a perirenal collection of liquid with diameter of 5 cm was detected. Perirenal collection of liquid was removed with preventional treatment and antibiotics regiments. Conclusion: PCNL with subcostal access for upper calices stones is a feasible and safe with low complication and can be performed instead of supracostal access tracts.

Abstract

Background and Objective: Electromagnetic waved generated by electronic industries and the increasing use of electrical appliances have led to higher rise in chronic exposure to extremely-low-frequency electromagnetic field (ELF-EMF). This study was done to investigate the effects of low electromagnetic field on mice embryos development. Materials and Methods: In this experimental study, eighty female NMRI mice were super ovulated and coupled with male mated over the night. Next morning the female mice with a vaginal plug were identified as pregnant mice. Animals allocated into 2 groups control group was not exposed to EMF and animals in case group exposed to 50 Hz and amp 1.2 mT EMF the pregnant mice were scarified by cervical dislocation at 24, 72, 81, 96, 110 and 120 hours. Embryos were subsequently obtained from the mice by flashing the fallopian tubule and uterus horn. Data were analyzed using SPSS-13.5, ANOVA and student’s t-tests. Results: The number of 2, 3-4 cells and 5-8 of embryo cells and blastocyst decreased in case group compared to controls, but these reduction were not significant. The number of morula in cases significantly reduced in comparison with control group (P<0.05). The average number of fragmented blastocyst in experimental groups siginficantly increased compared to control group (P<0.05). The number of inner cell mass and trophoectoderm in experimental group significantly reduced in comparison with controls (P<0.05). Conclusion: The exposure of extremely-low electromagnetic field in pregnancy reduces the number of morula, inner cell mass and trophoectoderm.
