Successful pregnancy with the use of vaginal pessary in a patient with a very short cervix. A case report.

Preterm birth is one of the causes of perinatal morbidity and mortality. The traditional treatment for a short cervix has been the cerclage in addition with the progesterone administration. Recently, the idea of using vaginal pessaries as a new less invasive method of treatment for the same indication is under discussion.

DNA flow-cytometric, histological and hormonal analysis of sertoli cell only syndrome (SECOS).

Sertoli cell only syndrome (SECOS) was identified on histology in 21 cases (16,28%) among 129 testicular biopsies performed in our department for azoospermia over the last 5 years. In these patients history, clinical features, hormonal levels, and histological findings were analyzed. In addition DNA flow-cytometric analysis was performed and showed an almost complete absence of haploid cells.

Multiple transrectal ultrasound guided prostatic biopsies: morbidity and tolerance.

Objective: Early detection of prostate cancer has become a matter of vital importance in modern societies. Ultrasound guided transrectal biopsy is the current standard urological procedure to detect prostate cancer. In this study our intention was to confirm the high tolerance and low complication rate of this procedure, facts already established in urologists' minds.

Extracorporeal shock wave lithotripsy for lower pole calculi: our experience.

Introduction: This study was performed in order to evaluate the immediate and long-term outcome of patients undergoing extracorporeal shock wave lithotripsy (ESWL) for isolated lower pole calculi.

Methods: Three hundred and seventy renal units of 350 patients (240 men and 110 women; mean age 55 years) with isolated lower pole renal stones of smaller than 2 cm2 were studied. Follow up ranged from 1 to 52 months (mean, 15 months) to time of censorship, significant period of secondary urologic evaluation.

Influence of preoperative vesicle biopsy on the decision for radical prostatectomy.

Purpose: The presence of seminal vesicle invasion (SVI) by prostate cancer is difficult to detect clinically and is associated with poor prognosis. The aim of our study was to identify the efficacy of transrectal ultrasound-guided seminal vesicle biopsies in the detection of seminal vesicle invasion (SVI) in patients with prostate cancer.

Materials And Methods: One hundred transrectal ultrasound-guided seminal vesicle biopsies were performed in 50 patients with clinically localized prostate cancer.

Early repair of injury to the ureter or bladder after hysterectomy.

In the present study we investigated the effectiveness of early diagnosis, repair of injuries to the ureter and urinary bladder sustained during hysterectomy, as compared to the results of delayed intervention. There were 46 ureteral injuries and 20 vesicovaginal fistulas in 55 patients. In 14 cases of ureteral injury an endoscopic approach management was employed.

The value of prostatic specific antigen density in the early diagnosis of prostate cancer.

In order to differentiate benign from malignant prostatic lesions, 42 patients were evaluated using the prostate specific antigen density (PSAD) test. All patients were evaluated with PSA determination, digital rectal examination (DRE), transrectal ultrasonography (TRUS) and ultrasound-guided prostatic biopsies. PSA was analyzed by the I-MX ABBOT assay.

Evaluation of needle biopsy in the diagnosis of prostatic carcinoma in men with prostatic intraepithelial neoplasia.

Prostatic intraepithelial neoplasia (PIN) is considered a premalignant lesion of the prostate. It is often encountered in prostate needle biopsy in cases where no cancer is identified. In order to evaluate its importance 25 patients with PIN in a former prostate needle biopsy underwent a second ultrasound guided needle biopsy.

Experience in 3,500 patients with urinary stones treated with the Dornier HM-4 bath-free lithotriptor.

During a 3-year period, hundreds of patients underwent ESWL treatment with the Dornier HM-3 and HM-4 lithotriptors operating at our institution. Our experience in 3,500 patients treated with the HM-4 bath-free lithotriptor is reported. Patients with radiolucent or cystine stones, stones larger than 3 cm or staghorn calculi, multiple stones with a total burden of more than 3 cm and those not amenable to follow-up were excluded from the study.

Extracorporeal shock wave lithotripsy of radiolucent urinary calculi using the Dornier HM-3 and HM-4 lithotriptors.

Between September 1992 and June 1995, 33 patients with radiolucent urinary calculi were treated in our hospital using Dornier HM-3 and HM-4 lithotriptors. There were 11 caliceal stones, 13 in the renal pelvis, and 9 in the ureter. Stone localization was achieved in only 30 patients using intravenous urography or retrograde urography through a ureteric catheter during the procedure.

Does free to total ratio of prostate-specific antigen alter decision-making on prostatic biopsy?

Objectives: For patients with prostate specific antigen (PSA) values of 4-10 ng/mL, some urologists perform prostatic biopsies depending upon the findings of digital rectal examination (DRE) and transrectal ultrasonography (TRUS), and others perform biopsies on most of these men regardless of the findings of DRE and TRUS. The purpose of this study was to examine whether the information given by the measurement of the ratio of free to total (F/T) PSA can alter decision-making on prostatic biopsy.

Methods: One hundred and two (102) men with PSA values between 4 and 10 ng/mL, were included in this study.

Double-pigtail stents for distal ureteral calculi: an alternative form of definitive treatment.

In this study, we treated patients with a solitary distal ureteral stone of less than 10 mm in maximum diameter by placing a double-pigtail stent and subsequently removing it allowing the calculus to pass spontaneously. A total of 40 patients were enrolled in the study with a mean stone size of 5.1 x 3.
