Introduction: High grade, non-muscle invasive bladder cancer (NMIBC) is usually treated with intravesical Bacillus Calmette-Guérin. Chemohyperthermia therapy (CHT) may be a novel alternative therapy for the treatment of NMIBC.

Objective: To evaluate the recurrence-free survival (RFS) of patients treated with CHT using the Combat bladder recirculation system (BRS) for NMIBC.

Article Synopsis
  • 1. Background: The study explores the effectiveness of hyperthermic intravesical chemotherapy (HIVEC) using mitomycin-C (MMC) as an alternative treatment for non-muscle invasive bladder cancer (NMIBC), especially during a shortage of BCG therapy.
  • 2. Methods: Researchers conducted an observational trial (HIVEC-E) on NMIBC patients in Spain from 2012 to 2020, evaluating treatment outcomes like recurrence, progression, and overall mortality, while monitoring safety and adverse effects.
  • 3. Results: 502 patients received a median of 8.78 HIVEC MMC treatments over a follow-up of about 24.5 months,

Unlabelled: Neoadjuvant chemohyperthermia (QHT) with MMC has demonstrated its efficacy in NMIBC both in the level of complete response at the time of TURBT and reduction of recurrences after several years of follow up. We present our experience with this treatment.

Methods: We performed a case control study in a group of 104 patients with middle-high risk NMIBC.

Objectives: The treatment of non muscle invasive bladder cancer (NMIBC) continues to be a challenge. Hyperthermia (HT) combined with intravesical chemotherapy is used to enhance the effects of chemotherapy.

Methods: A review of the publications was carried out to synthesize the adverse effects (AE) reported by the use of chemohyperthermia (QHT) with Mitomycin-C (MMC).

The urinary bladder is a fluid-filled organ. This makes, on the one hand, the internal surface of the bladder wall relatively easy to heat and ensures in most cases a relatively homogeneous temperature distribution; on the other hand the variable volume, organ motion, and moving fluid cause artefacts for most non-invasive thermometry methods, and require additional efforts in planning accurate thermal treatment of bladder cancer. We give an overview of the thermometry methods currently used and investigated for hyperthermia treatments of bladder cancer, and discuss their advantages and disadvantages within the context of the specific disease (muscle-invasive or non-muscle-invasive bladder cancer) and the heating technique used.

Objective: To evaluate the effectiveness of a readjustable sling for the treatment of male stress urinary incontinence (SUI).

Materials And Methods: Between October 2002 and August 2005, 51 male patients with mild to severe SUI were prospectively operated with the use of a readjustable sling (MRS) at seven different European hospitals: Spain (2), Italy (2), Greece (1), Germany (1), and Portugal (1). The origin of incontinence was radical prostatectomy in 43 cases, TUR in 4, and open prostatectomy in another 4.

Objectives: Due to the absence of randomized studies, the Spanish Reemex Working Group started a registry to analyze and review the results of a large group of patients with mid-term and long-term follow-up to obtain conclusions based on clinical experience.

Methods: A registry of 715 patients who underwent surgical intervention for insertion of the SUI readjustable prosthesis Reemex TRT (tension free readjustable tape) in 15 Spanish hospitals (40% urology departments, 60% gynecology departments). The registry was established to evaluate the safety and efficacy of the sling adjustability concept in the surgical treatment of female SUI.

Background And Purpose: Slings have been successful in the treatment of male stress urinary incontinence (SUI). However, in many situations, the sling may have either an excess of or inadequate tension, producing voiding difficulties or urinary leakage, respectively. The effectiveness of a readjustable sling for the treatment of male SUI has been evaluated.

Only seven cases of malignant renal or perirenal schwannomas have previously been reported in the literature. Herein we report the case of a 74-year-old female with a previous history of malignant subcutaneous schwannoma and breast ductal adenocarcinoma who presented with a renal mass that was preoperatively diagnosed as a metastatic schwannoma. This is the first case of malignant perirenal schwannoma of metastatic origin.

Background And Purpose: Slings, especially those called "tension free," have low complication rates and good long-term success rates. However, they still have problems with either an excess or a lack of tension, which produces voiding difficulties or urinary leakage persistence, respectively. The effectiveness of a new adjustable sling for the treatment of stress urinary incontinence (SUI) has been evaluated.

Background: A phase II multicentric trial of paclitaxel and cisplatin was conducted in previously untreated patients, with locally advanced transitional-cell carcinoma (TCC) of the bladder, to assess its toxicity and efficiency in preserving the bladder.

Methods: Forty-four patients with locally advanced TCC of the bladder (seven with T3a, 27 with T3b, and eight with T4a) were treated with paclitaxel 175 mg/m(2) over 3 h, and cisplatin 75 mg/m(2) over 30 min, on the first day of each 21-day treatment cycle. Therapy was continued for three cycles.

Objective: To report a case of testicular tumor, classified as seminoma, with a very uncommon form of presentation since it presented as acute scrotum.

Methods: The clinical features, treatment and outcome of this uncommon condition are presented.

Results: A review of the literature showed that this form of presentation is rare although in the present case it is impossible to determine if testicular inflammation was due to tumor necrosis or infection from the associated hydrocele.
