Objectives. To evaluate the efficacy of a 7F tail stent with an 18F Councill nephrostomy tube and compare it to a 24F re-entry Malecot nephrostomy tube after percutaneous nephrolithotomy.Methods. Forty patients were prospectively randomized to receive either a 24F re-entry Malecot nephrostomy tube (group A, n = 20) or a 7F tail stent with an 18F Councill nephrostomy tube (group B, n = 20) for postoperative...
Objectives. To evaluate whether the dilated renal pelvis can be used as an autologous source for the surgical reconstruction of upper ureteral defects or strictures.Methods. In 7 female pigs, the renal pelvis was expanded by a percutaneously placed Council balloon catheter. Every other day for 4 weeks, the renal pelvis was progressively dilated with a bolus injection of saline and contrast medium,...
Objectives. The purpose of this study was to evaluate whether repair of the ureteropelvic junction (UPJ) obstruction reduces the incidence of stones in stone-forming patients with concurrent UPJ obstruction.Methods. We performed a retrospective study evaluating 90 patients with UPJ obstruction who underwent endopyelotomy and simultaneous stone extraction (group A) and 80 patients without UPJ obstruction...
Objectives. During the past 10 years, numerous reports around the world have documented the safety and success rate of antegrade endopyelotomy. We describe the classic endopyelotomy in conjunction with some new alternatives for making the incision.Technical Considerations. Antegrade endopyelotomy is performed through the 0.5-in. incision of the percutaneous nephrostomy created by way of an upper or...
Objectives. To evaluate the erectile function (EF) domain of the International Index of Erectile Function (IIEF) as a diagnostic tool to discriminate between men with and without erectile dysfunction (ED) and to develop a clinically meaningful gradient of severity for ED.Methods. One thousand one hundred fifty-one men (1035 with and 116 without ED) who reported attempting sexual activity were evaluated...
Objectives. To evaluate the efficacy, safety, and tolerability of sildenafil in men with broad-spectrum erectile dysfunction (ED), with reference to age-matched healthy control subjects.Methods. One hundred eleven patients were enrolled in a randomized, double-blind, placebo-controlled, parallel-group, 12-week, flexible-dose study. Efficacy assessments included the International Index of Erectile...
Objectives. We investigated the in vitro nonthermal effects of microwaves delivered from Prostatron 2.0 on Escherichia coli and Enterobacter cloacae.Methods. The fingers of powder-free, sterile gloves were ligated, and bacterial solutions were transferred into the remaining area of the glove. The gloves were then sealed using silk ligatures. One set of gloves was subjected to the microwave treatment...
Objectives. This is the first and largest single institution retrospective study in the United States to examine the effects of transurethral microwave thermotherapy (TUMT) for the treatment of benign prostatic hyperplasia (BPH).Methods. From September 1996 to June 1997, 78 men with moderate to severe symptomatic BPH were treated with the Prostatron at our institution. Patient age ranged from 52 to...
Objective. Lymphocele formation has been infrequently reported as a complication of laparoscopic pelvic lymph node dissection (LPLND). We determined the incidence of clinical and subclinical lymphocele formation in patients undergoing transperitoneal LPLND.Methods. Charts and radiological records of 111 patients undergoing transperitoneal LPLND at this institution between January 1991 and December...
Objectives. A Phase I trial of photodynamic therapy (PDT) in the treatment of superficial transitional cell carcinoma (TCC) of the bladder was performed.Methods. Twenty patients with recurrent superficial TCC of the bladder after receiving a mean of 2.6 (range 1 to 6) courses of intravesical therapy were treated with PDT. The photosensitizer Photofrin II dose was 1.5 or 2.0 mg/kg. A 630-nm intravesical...
Objectives. To evaluate the long-term results of the UroLume endourethral prosthesis for the treatment of recurrent bulbar urethral strictures.Methods. In a multicenter, prospective study 175 patients with recurrent bulbar urethral strictures were enrolled in a Food and Drug Administration (FDA) trial of the UroLume endourethral prosthesis. One hundred thirty-nine patients were available for follow-up...
Objectives. To determine the incidence of negative hematuria in patients with acute urinary lithiasis presenting to the emergency room with flank pain.Methods. We retrospectively reviewed all 140 patients who presented with flank pain to the Long Island Jewish Medical Center emergency department from January 1, 1992, through December 31, 1992, and underwent intravenous urogram (IVU). We then calculated...
We present an interesting application of laparoscopy in a man who was otherwise not a candidate for radiotherapy because of an adherent loop of small bowel in the proposed treatment field. Laparoscopic enterolysis was performed and the involved segment was displaced out of the pelvis; a synthetic mesh was placed to serve as a sling to prevent caudal migration back into the pelvis. The patient had...
