Perirenal candidial abscess [Case Report]

Provet J; Gluck R; Golimbu M
Perirenal candidial abscesses are rare, with few well-documented cases in the literature. We describe a case of a perinephric abscess treated with amphotericin B and nephrectomy

Anastomotic strictures following radical prostatectomy: risk factors and management

Surya, B V; Provet, J; Johanson, K E; Brown, J
Stricture of the anastomosis between the bladder neck and membranous urethra after radical prostatectomy can cause significant voiding dysfunction. Of 156 patients undergoing radical prostatectomy for localized prostatic carcinoma 18 had anastomotic stricture for an over-all incidence of 11.5%. The risk factors for anastomotic stricture and the treatment outcome in these patients were analyzed. Excessive intraoperative blood loss, extravasation of urine at the anastomotic site and a prior transurethral prostatic operation significantly contributed to the development of stricture. More than half of the patients did not respond to simple dilation alone. Cold knife incision of the stricture by itself was effective in only 62% of the patients. The remaining patients required periodic dilation to maintain an adequate urine flow. Incision of the stricture with electrocautery resulted in urinary incontinence in all patients

Scrotal island flap urethroplasty in the management of bulbar urethral strictures

Provet, J A; Surya, B V; Grunberger, I; Johanson, K E; Brown, J
We describe our experience with 20 patients undergoing 1-stage scrotal island flap urethroplasty for severe bulbomembranous stricture disease. While 16 patients achieved satisfactory results, 4 required revision for recurrent stricture, diverticulum or fistula. Use of hairless skin and aggressive tailoring of the flap are stressed to avoid the common complications of diverticulum, hair ball and stone formation. This highly vascularized pedicle represents a reasonable alternative to staged repair when local tissue scarring is great and free full thickness skin graft viability is questionable

Primary amyloidosis of urethra [Case Report]

Provet, J A; Mennen, J; Sabatini, M; Rakhman, J; Golimbu, M
Primary localized amyloidosis of the urethra is rare; only 17 cases reported to date. Its clinical importance is significant, however, in that its presentation mimics carcinoma and treatment should be conservative. We describe an additional case and briefly review the literature

Simultaneous repair of bilateral ureteropelvic junction obstruction

Provet JA; Hanna MK
Fifteen children with bilateral ureteropelvic junction obstruction underwent simultaneous repair as a single procedure. Dismembered pyeloplasty and ureterocalycostomy were the two procedures used. Ten were performed through anterior subcostal incisions. Posterior lumbotomy provided adequate exposure in 5 children and further contributed to shortened hospitalizations. The functional and anatomic results were excellent. Simultaneous bilateral pyeloplasty through posterior lumbotomy is a safe and cost-effective alternative to staged procedures for bilateral ureteropelvic junction obstruction

Intravesical bacillus Calmette-Guerin therapy for in situ transitional cell carcinoma involving the prostatic urethra

Bretton, P R; Herr, H W; Whitmore, W F Jr; Badalament, R A; Kimmel, M; Provet, J; Oettgen, H F; Melamed, M R; Fair, W R
A total of 23 patients presenting with multifocal superficial bladder cancer and concomitant in situ transitional cell carcinoma of the prostatic urethra (mucosal in 19 and ductal in 4) underwent transurethral resection and intravesical bacillus Calmette-Guerin therapy. Median followup was 51.6 months (range 6 to 105 months). Of the 23 patients 13 (48 per cent) had a complete response with a median followup of 43.7 months without recurrence. Progression of some type (local, muscle invasion or metastasis) occurred in 10 patients (44 per cent); none occurred in the prostatic urethra. Median interval free of progression was 55.7 months; 7 of 10 patients required cystectomy for progression or refractory disease in the bladder (prostate negative for transitional cell carcinoma). A trial of complete transurethral resection plus intravesical bacillus Calmette-Guerin is a viable alternative to immediate radical cystectomy for patients with mucosal and/or ductal involvement of the prostatic urethra with in situ transitional cell carcinoma

Experience with potency preservation during radical prostatectomy. Significance of learning curve

Surya, B V; Provet, J; Dalbagni, G; Johanson, K E; Brown, J
Potency preservation after radical prostatectomy is relatively new. The efficacy of this procedure has not been widely documented. Twenty-four patients with full potency underwent nerve-sparing radical prostatectomy. A total of 12 patients retained potency after surgery. Analysis of data reveals there is a learning curve in doing this procedure, and once the initial learning phase is over good results can be obtained in a select group of patients

Radical prostatectomy for stage D1 prostate cancer. Prognostic variables and results of treatment

Golimbu M; Provet J; Al-Askari S; Morales P
Surgical extirpation of the primary tumor together with the involved regional nodes has been considered ineffective treatment for locally disseminated prostatic carcinoma. We retrospectively reviewed our experience with 42 patients with Stage D1 disease who underwent radical prostatectomy and bilateral pelvic lymphadenectomy and who had a follow-up of one to thirteen years (mean 5 years). The following variables affecting survival and tumor progression were analyzed: (1) tumor grade and local extent; (2) number of positive lymph nodes, and (3) adjuvant therapy. The overall five- and ten-year survival was 79.5 per cent and 28 per cent compared with the expected survival of an age-matched control group of 88 per cent and 28 per cent, respectively. The degree of tumor differentiation had no effect on prognosis, but local tumor bulk and the number of involved lymph nodes significantly changed the disease progression and survival rate. Patients with low local tumor bulk and one positive node survived as long as the age-matched male population group. Our data suggest that radical prostatectomy may represent a valuable treatment in selected patients with Stage D1 prostate carcinoma

Prognosis of patients with pathologic stage II cutaneous malignant melanoma

Roses DF; Provet JA; Harris MN; Gumport SL; Dubin N
The prognostic relevance of the extent of nodal metastases, lesion thickness, level of invasion, site of lesion, satellitosis, age, sex, and year of diagnosis and treatment were assessed in 213 consecutive patients with pathologic Stage II malignant melanoma (157 with clinical Stage I disease and 56 with clinical Stage II disease). Of these factors, only three were significant: 1) clinical status of the lymph nodes (p less than 0.0001); 2) thickness of the primary lesion in the ranges of less than 2.0 mm, 2.0 to 4.9 mm, and 5.0 mm or greater (p = 0.002); and 3) level of invasion (p = 0.0002). The extent of nodal metastases in those patients with clinical Stage I disease was not significant. The difference in survival between patients with clinically negative/histologically positive nodes (clinical Stage I) and clinically positive/histologically positive nodes (clinical Stage II) was apparent throughout the follow-up period. The 5- and 10-year survival rates for the clinical Stage I patients were 44% and 28%, respectively, and for the clinical Stage II patients 21% and 12%, respectively (p less than 0.0001). A 5-year cumulative survival rate of 65% was achieved for clinical Stage I patients having primary lesions of less than 2.0 mm in thickness, while it was 19% for patients having primary lesions of 5.0 mm or more in thickness. For pathologic Stage II malignant melanoma patients, prognosis is most dependent on the clinical status of the lymph nodes, not on the number of lymph nodes with micrometastases
