Is It Possible to Predict Sepsis, the Most Serious Complication in Prostate Biopsy?

Objective: Prostate biopsy for the diagnosis of prostate cancer by transrectal ultrasonography (TRUS) is a common procedure used in daily urology practice with a low complication rate and easy applicability. In this study, the precipitating factors and prophylaxis for sepsis, the worst complication of the procedure, were assessed. Patients and Methods: 2,023 patients with suspected prostate cancer who underwent biopsy by TRUS in one center were assessed retrospectively. The relationship between sepsis and age, serum total prostate-specific antigen (PSA) level, PSA density, prostate volume, number of biopsies, number of repeated biopsies, accompanying diagnosis of prostatitis, presence of urethral catheter, and presence of diabetes mellitus was assessed. Data were analyzed using the t test and logistic regression analysis. Results: Of the 2,023 patients, 62 (3.06%) developed sepsis within 5 days after biopsy. There was no significant relationship between the biopsy and the above parameters using the logistic regression analysis. Using the t test, it was found that the number of biopsy cores (p < 0.001), presence of urethral catheter (p < 0.0001), and presence of diabetes mellitus (p < 0.0001) were predictive factors for sepsis. Conclusion: Sepsis is a rare but life-threatening complication after prostate biopsy by TRUS. Although preoperative prophylactic oral antibiotics and enema before biopsy have proven to be effective in decreasing urinary tract infection rates, patients with urethral catheter, diabetes mellitus or those to undergo biopsy from more sites than ten cores should be closely monitored after biopsy.

A comparison of p21 and p27 immunoexpression in benign glands, prostatic intraepithelial neoplasia and prostate adenocarcinoma

To assess the immunoexpression of p21 and p27 proteins in consecutive areas of benign glands, prostatic intraepithelial neoplasia (PIN) and prostate adenocarcinoma.

Amyloidosis of seminal vesicles; incidence and pathologic characteristics.

OBJECTIVE Amyloidosis is a rare disease with various etiologies with extracellular amyloid protein depositions. At present, at least 26 distinctive amyloid forms have been detected with different clinical importance and treatment. They have characteristic staning fetaures with Congo red. Amyloid may be detected in 2-10% of prostates that have been removed because of hyperplasia or carcinoma. Amyloidosis of seminal vesicles is accepted as senil amyloidosis and it is not accompanied by systemic amyloidosis or clinical symptoms. This condition is the most common form of localized amyloidosis. In this study we aimed to investigate incidence and histologic characteristics of amyloidosis of seminal vesicles in radical prostatectomy materials of the patients whose prostate carcinomas were treated surgically. MATERIAL AND METHOD Amyloid depositions in seminal vesicles of 207 radical prostatectomy materials that prostates had been removed due to localized prostate carcinoma. Amyloid depositions were confirmed with Congo red staining and polarization microscope. RESULTS Amyloidosis of seminal vesicles was detected in 10 (4.8%) of cases. Mean age of the patients is 66.2 years. Amyloid depositions tend to be nodular and bilateral in subepithelial region of affected seminal vesicles. Amyloid depositions were not detected in blood vessels in seminal vesicles or prostate parenchyma. CONCLUSION Localized amyloidosis of seminal vesicles is not an unusual finding. amyloidosis of seminal vesicles incidence in Turkish patients included in this study and histopathologic characteristics of these patients are not different from the other studies. Systemic AA amyloidosis is the most common form of amyloidosis in our country. To be aware of amyloidosis of seminal vesicles is of importance in discrimination from the other forms of amyloidosis.

Giant Ectopic Ureter Mimicking Pelvic Organ Prolapse: A Case Report

Ectopic ureter is one of the most common urinary tract anomalies. We, herein, present a case of a giant ureter with ectopic orifice, mimicking pelvic organ prolapse, which is the first in the literature. A 59-year-old female patient presenting with frequently recurrent urinary tract infection had grade 3 pelvic organ prolapse. On examination, the organ producing the appearance of prolapse was found to be a right ureter of giant size and was obstructed by a large stone at the distal segment. The proximal end of the ureter ended blindly. After exploration, the stone was removed, the ureter was detached from the urethra, and the lumen was tied off and cut 5 cm proximally. At 6 months postoperatively, the patient is being followed up without any clinical problems. In such cases with nonfunctioning renal segment draining proximally, the chance of cure can be obtained without a need for a comprehensive intervention such as total abdominal ureterectomy.

Acinar adenocarcinoma of prostate with predominant ttf-1 positive intraductal component

Intraductal carcinoma of prostate has been previously described in radical prostatectomies. Its rarely encountered in needle biopsies in the absence of infiltrative carcinoma. But, both histogenesis and nomenclature of the lesion is still controversial. Among the pure intraductal carcinoma of prostate cases, a different solid patern was described with smaller nuclei at the center of the ducts. However, there is a lack of information about the association of those cases with acinar prostate adenocarcinoma. Herein, we describe a case of acinar adenocarcinoma with predominant non-neuroendocrine TTF-1 positive small cell intraductal component.

Congenital adrenal hyperplasia: a rare cause of renal failure and a successful renal transplantation.

Congenital adrenal hyperplasia belongs to a group of autosomal recessive disorders affecting steroid biosynthesis; a rare disease with a prevalence of 1 case per 16,000 population. A 30-year-old phenotypically male patient had been diagnosed with 11-β hydroxylase deficiency at the age of 16; presenting with ambiguous genitalia, growth retardation, presence of menstrual cycles, severe hypertension, hypokalemia and renal dysfunction. He developed endstage renal disease due to hypertension and was treated with hemodialysis for 3 y. After careful evaluation, he was approved to undergo renal transplantation. The patient has now finished 6th month after transplantation and is currently under follow-up at our outpatient clinic, having no problems related to the transplant. While early treatment to prevent hypertension is mandatory in patients with congenital adrenal hyperplasia, once renal failure occurs, renal transplantation may the best choice of treatment. In this study, we describe the first report of a successful renal transplantation in an adrenal hyperplasia.

Biochemical Recurrence After Radical Prostatectomy: is the Disease or the Surgeon to Blame?

PURPOSE The PSA recurrence develops in 27 to 53% within ten years after radical prostatectomy (RP). We investigated the factors (disease grade and stage or the surgeons expertise,) more likely to influence biochemical recurrence in men post-radical prostatectomy for organ-confined prostate cancer by different surgeons in the same institution. MATERIALS AND METHODS A total of 510 patients that underwent radical prostatectomy were investigated retrospectively. Biochemical recurrence was defined as detection of a PSA level of ≥ 0.20 ng/mL by two subsequent measurements. The causes, which are likely to influence the development of PSA recurrence, were separated into two groups as those related to the disease and those related to the surgical technique. RESULTS Biochemical recurrence was detected in 23.5% (120 cases) of 510 cases. The parameters most likely to influence biochemical recurrence were: PSA level (p < 0.0001), T stage (p < 0.0001), the presence of extracapsular invasion prostate (p < 0.0001), Gleason scores (p = 0.042, p < 0.0001) and the presence of biopsy with perineural invasion (p = 0.03). The only surgical factor that demonstrated relevance was inadvertent capsular incision during the surgery that influenced the PSA recurrence (p < 0.0001). CONCLUSION The PSA recurrence was detected in 21.6% of patients who had been treated with radical prostatectomy within 5 years, which indicates that the parameters related to the disease and the patient have a pivotal role in the PSA recurrence.
