To determine the role of laparoscopic surgery in the treatment of urachal disorders.A case report and literature review of laparoscopic urachal cyst procedures.A 21-year-old man presented with a draining sinus at the umbilicus. A diagnosis of a urachal sinus was made. The patient underwent a laparoscopic excision of the sinus and cyst.Minimally invasive techniques such as laparoscopic surgery are...
The influence of acute appendicitis (AA) on the right kidney and urinalysis was investigated. Permanent damage of the urinary tract and abnormal urinalysis have been previously reported in AA.Appendectomy was performed in 84 patients with no previous urogenital, retroperitoneal, or pelvic disease, trauma, or operation. AA was confirmed in 66 of them. Control groups were the remaining 18 patients and...
Contrary to previous belief, the existence of a muscularis mucosa in the human urinary bladder has now been well described. Although the degree of development of this structure seems variable, it can frequently be used to differentiate two levels within the subepithelial connective tissue: the lamina propria and the submucosa. The present study evaluates whether this morphologic feature is potentially...
Artists' pigments have been used in more than 150 radical prostatectomy specimens and many other malignant surgical specimens for detecting positive surgical margins. Their advantages are rapid drying, resistance to tissue processing, and the ability to mark many planes of excision simultaneously with different colors.
There is controversy concerning the management of small unilateral renal cell carcinomas. The present study was undertaken to evaluate the relative efficacy of radial nephrectomy versus nephron-sparing surgery in such patients.Patients with a single, small (less than 4 cm), localized, unilateral, sporadic renal cell carcinoma (IRCC) were identified from an institutional registry. From 1975 to 1992,...
Digital rectal examination (DRE) is an important method of prostate cancer detection used by primary care physicians and medical specialists to identify patients in whom a prostatic biopsy is warranted. However, there is little empirical evidence assessing the degree of interexaminer variability in the use of DRE for the detection of prostate cancer. We addressed this issue within the framework of...
Report have demonstrated that African Americans diagnosed with prostate cancer have a poor survival compared with whites. We examined the impact of age, race, and stage of disease on survival for men diagnosed with prostate cancer.A retrospective analysis was madeof men diagnosed with prostate cancer utilizing the Surveillance, Epidemiology, and End Results Program (SEER) database. A total of 12,907...
Adult onset enuresis accompanied by ostructive sleep apnea has been reported rarely. A female patient was referred to our clinic with complaints of a 15-year history of loud snoring and sleep apnea as well as enuresis, which was treated successfully with imipramine and acetazolamide. The mechanism of enuresis and its relationship to upper airway obstruction area reviewed here with reference to the...
Rreport of initial clinical experience with seromuscular colocytoplasty lined with urothelium (SCLU), a new operation to increase bladder capacity and compliance without incorporating intestinal mucosa into the urinary tract. We have previously reported the technique and results of this procedure in a canine model.Sixteen patients underwent SCLU at two institutions. Their charts were reviewed retrospectivelY...
Excessive formation of reactive oxygen species (ROS) in human semen has been associated with impaired sperm function and fertility potential. The presence of ROS in semen specimens from normal fertile men emphasizes the importance of defining a normal range of ROS formation. The purpose of this study was to establish a normal range of ROS generation and to investigate the effect of sperm concentration...
We report on 3 cases of femoral neuropathy following radical surgery for urologic malignancy. The defect was bilateral in 2 patients. Compression from self-retaining retractors was the presumed mechanism of injury in all patients. Spontaneous improvement was observed in each case although the symptoms did not resolve completely. The pathophysiology contributing to this operative complication as well...
We describe a new stent made from shape memory alloy (SMA) first devleoped by our collaborative group, its structure, and a simple and easy procedure for its placement and removal without the need for a monitoring system or sedation.The stent made of SMA was placed in 5 dogs for 10 months. It was left in situ in the shape of thermal expansion while the obturator Foley catheter was removed.Placement...
Experimental evidence suggests that transparenchymal suture fixation may risk testicular damage. Even very small sutures can result in inflammation and tubular damage. An alternative to transparenchymal suture fixation of the testis is presented.
We describe teh course of acute renal infarction, without a demonstrable cause, in an otherwise healthy young male. Renal function was not compromised, and the infarct failed to progress. Literature on relevant diagnostic and therapeutic modalities is reivewed.
To examine the effects of intravesical suramin on N-methyl-N-nitrosurea (MNU)-induced bladder tumors in Fischer 344 rats.Multiple cohorts of female rats received four biweekly intravesical instillations of MNU. A control group received no other treatment, the experimental group received 25 mg/kg intravesical suramin twice a week beginning at week 6.After 18 weeks from the first instillation of MNU,...
