Does skip metastasis or other lymph node parameters have additional effects on survival of patients undergoing radical cystectomy for bladder cancer?

Purpose: To investigate the effects of lymph node metastasis, skip metastasis, and other factors related to lymph node status on survival in patients who underwent radical cystectomy (RC) and extended lymph node dissection (eLND).

Materials And Methods: RC and eLND were performed in 85 patients with a diagnosis of bladder cancer. Disease-free survival (DFS) and overall survival (OS) were determined by using a Cox proportional hazards model that included the number of excised lymph nodes, the presence of pathological lymph node metastasis, the anatomical level of positive nodes, the number of positive lymph nodes, lymph node density, and the presence of skip metastasis.

Materials And Methods: We used the database of our previous prospective multicenter study. A total of 118 patients underwent RC and extended PLND.

The effects of transurethral resection of the prostate on morbidity and mortality in patients with nondialysis-requiring renal insufficiency.

Objectives: To compare the prevalence of preoperative co-morbid factors and complications of transurethral resection of prostate (TUR-P) in patients with normal and non-dialysis requiring elevated serum creatinine levels.

Methods: The records of 357 consecutive patients with IPSS≥20, serum creatinine level ≤ 3 mg/dl, residual urine volume ≤ 300 ml and with no upper urinary tract dilatation or evidence of prostate cancer that underwent TUR-P were retrospectively evaluated. 60 patients who did not fulfill the inclusion criteria were excluded.

The correlation among the percentage of positive biopsy cores from the dominant side of prostate, adverse pathology, and biochemical failure after radical prostatectomy.

The aim of this study was to evaluate the correlation among various preoperative clinical variables, including certain prostate needle biopsy parameters, biochemical failure, and adverse pathology, after radical retropubic prostatectomy (RRP). We retrospectively evaluated the records of our 156 patients who underwent RRP because of localized prostate cancer. Serum prostate-specific antigen level, clinical stage, and the information obtained from biopsy [Gleason score, number of positive cores, percentage of positive cores (PPCs) from the dominant side of prostate, and overall PPC] were evaluated as predictors of adverse pathology and biochemical failure.

Methods: A total of 197 male patients of reproductive age who applied to our clinic between December 2004 and June 2005 with various scrotal complaints were included in the study. Patient complaints were of pain, swelling, smallness of the testes, and infertility.

Comparison of four different anesthesia methods for relief of all pain during transrectal ultrasound-guided prostate biopsy.

Introduction: To find the most beneficial method, we assessed patient comfort and morbidity rates during prostate biopsy procedures performed using periprostatic nerve blockade, unilateral pudendal nerve blockade, intrarectal lidocaine gel, and a combination of periprostatic nerve blockade and intrarectal lidocaine gel.

Materials And Methods: A total of 159 patients were included in this study. Pain evaluation results were retrospectively assessed and retrieved from the patient charts.

Can pain during digital rectal examination help us to decide the necessity and the method of anesthesia for transrectal ultrasound guided prostate needle biopsy?

Objective: Transrectal ultrasound (TRUS) guided prostate biopsy is well tolerated by patients but the lack of an effective marker to predict pain prevents us from determining pre-procedurally which patient group needs local anesthesia for biopsy and probe pain. Thus in this study, we investigated predictor factors for prostate biopsy and probe insertion pain.

Materials And Methods: 71 patients who were undergoing prostate biopsy without anesthesia were included in the study retrospectively.

Effects of simultaneous transurethral resection of prostate and solitary bladder tumors smaller than 3 cm on oncologic results.

Objectives: To investigate the effect on the oncologic outcomes of treatment with transurethral resection of patients with a solitary bladder tumor smaller than 3 cm with a superficial appearance and benign prostatic hyperplasia.

Methods: The follow-up data from 34 men (group 1) who had undergone transurethral bladder tumor resection alone and 31 men who had undergone both transurethral prostate resection and transurethral bladder tumor resection at the same operation (group 2) in our clinic from 1996 to 2004 were retrospectively examined. The groups were also compared with each other.

Embryonal paratesticular rhabdomyosarcoma: a case of young adult patient who has inguinal relapse.

Scrotal rhabdomyosarcomas originating from paratesticular tissue are most frequently seen in childhood and young adulthood. These are rarely seen malignant tumors. We present a young male with inguinal relapse in the early period that we had achieved a good clinical outcome with chemotherapy and radiotherapy protocols.

Reliability of frozen section examination of external iliac, hypogastric, and obturator lymph nodes during radical cystectomy: a multicenter study.

Objectives: To evaluate the accuracy of frozen section examination (FSE) for detecting lymph node (LN) metastasis in patients with bladder cancer undergoing radical cystectomy and pelvic LN dissection. To our knowledge, the accuracy of FSE to identify LN metastases in patients with bladder cancer is still undetermined.

Methods: The clinical data of 360 patients who had undergone radical cystectomy with pelvic lymphadenectomy for bladder cancer in six urologic institutions were retrospectively analyzed.

A large seminal vesicle cyst with contralateral renal agenesis.

Seminal vesicle cysts (SVC) are rather rare disorders. Our case is the first in literature where contralateral renal agenesis was seen together with SVC and surgically managed. We believe that the occurrence of these two coinciding abnormalities is incidental.

Value of frozen sections of lymph nodes in pelvic lymphadenectomy in patients with invasive bladder tumor.

Aim: We examined the reliability of classical lymph node evaluation methods. We compared the results of preoperative computed tomography (CT) and perioperative frozen section examination of lymph nodes in patients on whom radical cystectomy was performed because of invasive bladder tumors.

Methods: A total of 142 patients, in whom radical cystectomy was performed because of invasive bladder tumors between the years 1994 and 2005 in our clinic, and 284 pelvic lymph node regions were evaluated retrospectively.

How do patients with familial benign prostatic hyperplasia differ clinically from those with sporadic benign prostatic hyperplasia?

Introduction: The aim of this study was to compare age, prostatic volume, International Prostate Symptom Score (IPSS), maximal flow rate, serum total prostate-specific antigen (PSA), serum free PSA, free/total PSA ratio and PSA density values of familial and sporadic benign prostatic hyperplasia (BPH) patients suffering moderate or severe lower urinary tract symptoms.

Materials And Methods: Between September 1999 and August 2004, 511 patients with moderate or severe lower urinary tract symptoms (IPSS > or =8) due to BPH were included in the study. Patients with at least 2 first-degree relatives who had undergone surgery or received medication for BPH were classified as having the familial form of the disease, while the remaining patients were taken as sporadic cases.

Unilateral pudendal nerve blockade for relief of all pain during transrectal ultrasound-guided biopsy of the prostate: a randomized, double-blind, placebo-controlled study.

Objectives: To investigate the efficacy of unilateral pudendal nerve block for the relief of all pain during transrectal ultrasound (TRUS)-guided prostate biopsy. TRUS-guided prostate biopsy is the standard procedure to diagnose or rule out prostate cancer. The pain, attributed to ultrasound probe insertion and the needle punctures into the prostate, inflicted by TRUS-guided prostate biopsy limits its effectiveness.

Effects of forced diuresis achieved by oral hydration and oral diuretic administration on uroflowmetric parameters and clinical waiting time of patients with lower urinary tract symptoms.

Introduction: We studied the impact of diuresis forced by oral hydration or single-dose oral diuretic administration on uroflowmetric parameters and clinical waiting time of patients with lower urinary tract symptoms.

Patients And Methods: A total of 58 patients with a mean age of 59 (range 41-77) years who presented with lower urinary tract symptoms were included in the study. The patients were grouped with respect to their International Prostate Symptom Scores as having mild, moderate, or severe symptoms.

The early effects of partial outflow obstruction on contractile properties of diabetic and non-diabetic rat bladder.
