Prostate cryosurgery has been increasingly used for the management of localized prostate cancer since its introduction in a minimally invasive form in the early 1990s. We performed a retrospective study of the largest and most mature patient group treated with cryosurgery reported thus far.We retrospectively analyzed the data from 370 patients treated consecutively from 1991 to 1996 with a focus on...
The issue of prostate cancer screening and management is likely to assume greater importance with progressive aging of the population. Because there are no currently established guidelines for screening and management of prostate cancer in elderly men (older than 75 years), a multidisciplinary panel was convened to develop consensus recommendations.The panel consisted of experts in urology, internal...
To detect citrate levels in fresh tomato juice, to reveal whether it can be studied for prevention of recurrent hypocitraturic nephrolithiasis.Juices of tomato, orange, lemon, and mandarin were extracted and blended with a hand blender, and 10 samples of 100 mL were taken from each. Citrate, oxalate, calcium, phosphorus, magnesium, sodium, potassium, chloride, and pH levels were examined in these...
Metastatic small cell carcinoma of the prostate portends a poor prognosis. Survival expectancy is generally estimated in months with few reports in the literature of patients surviving more than 2 years. We report a case of one of the longest known surviving patients in continuous complete remission with metastatic small cell carcinoma of the prostate and review the available literature reporting...
Conformal radiotherapy with adjuvant androgen suppression is used in our center to treat localized prostate cancer. We compare Phoenix as an alternative to American Society of Therapeutic Radiology and Oncology (ASTRO) for defining biochemical failure. Our primary aim was to assess the Phoenix and ASTRO definitions of biochemical failure in a population of mainly Asian men with early localized prostate...
To determine whether physician-diagnosed prostatitis was associated with later development of benign prostatic hyperplasia (BPH)-associated events in a longitudinal, population-based sample of 2447 men residing in Olmsted County, Minnesota.Medical records were reviewed for physician diagnosis of prostatitis and subsequent diagnoses of BPH, enlarged prostate, prostatism, and acute urinary retention...
To compare different tools for evaluate prostate-specific antigen (PSA) kinetics before prostate biopsy, such as PSA velocity, PSA slope, natural logarithm PSA slope (lnPSA slope), and PSA doubling time (PSADT).This study was conducted involving 325 male patients evaluated with transrectal ultrasound-guided biopsy of prostate. Patients with at least three consecutive PSA measurements taken in at least...
Perineal apocrine carcinoma is a rare malignant tumor that has its origin in the apocrine sudoriparous glands of the genital and perianal regions. It often progresses quietly and metastasizes in the superficial inguinal and retrorectal lymph nodes. We report a case of a genital apocrine carcinoma located at the penile basis. To our knowledge our report represents the first case of a pathologically...
To further evaluate the mechanism of action of phosphodiesterase (PDE) inhibitors on the human prostate, the effects of PDE4 and PDE5 inhibitors on the tension induced by norepinephrine (NE) and on the intracellular levels of cyclic nucleotides in isolated human prostatic tissue were investigated.Using the organ bath technique, the effects of increasing concentrations (1 nM to 10 μM) of the PDE5 inhibitors...
Transverse testicular ectopia (TTE) is an extremely rare congenital anomaly in which both testes descend through the same inguinal canal. We report an 8-month-old male with TTE and hypospadias. To help manage the patient, we conducted laparoscopy to elucidate the anatomy of the spermatic cord of the ectopic testis. On laparoscopy, we clearly identified the spermatic cord of the right ectopic testis...
