RESUMO

BACKGROUND: In urology, a subset of patients with lifelong urine drainage are fitted with a catheter valve. Data on catheter-related quality of life (crqol) in this subset of patients are missing. AIM: Clarification of the whether there are advantages for valve-aided catheters in comparison with continuous urine drainage in catheter wearers with a lifelong indication. METHODS: In all, 357 patients with a catheter with lifelong indication of continuous urine drainage from a previous study were compared with 70 valve-aided patients. The crqol was evaluated by a validated assessment with 25 items and five domains. RESULTS: There were statistically more patients with a suprapubic catheter than with a transurethral indwelling catheter (73.4 vs. 54.4%, p = 0.005), significantly more patients with bladder voiding dysfunction (73.5 vs. 52.6%, p = 0.003) and significantly more patients with small catheter sizes (p = 0.001). Crqol was altogether slightly impaired with a median score of 4.2 (no impairment indicated by 5 points) in valve-aided patients, but crqol was more impaired in valve-aided patients compared to patients with continuous drainage (4.4 points, n. s.). Some items demonstrated more problems dealing with urinary urge in valve-aided patients, but catheter-related pain was more often worse in patients with continuous drainage. CONCLUSION: There is no clear evidence for an advantage of a catheter valve over a continuous urine drainage system. Thus, the decision regarding a catheter-valve system must be made individually according to the indication and the preferences of the patient.

RESUMO

RNA interference is required for post-transcriptional silencing, but also has additional roles in transcriptional silencing of centromeres and genome stability. However, these roles have been controversial in mammals. Strikingly, we found that Dicer-deficient embryonic stem cells have strong proliferation and chromosome segregation defects as well as increased transcription of centromeric satellite repeats, which triggers the interferon response. We conducted a CRISPR-Cas9 genetic screen to restore viability and identified transcriptional activators, histone H3K9 methyltransferases, and chromosome segregation factors as suppressors, resembling Dicer suppressors identified in independent screens in fission yeast. The strongest suppressors were mutations in the transcriptional co-activator Brd4, which reversed the strand-specific transcription of major satellite repeats suppressing the interferon response, and in the histone acetyltransferase Elp3. We show that identical mutations in the second bromodomain of Brd4 rescue Dicer-dependent silencing and chromosome segregation defects in both mammalian cells and fission yeast. This remarkable conservation demonstrates that RNA interference has an ancient role in transcriptional silencing and in particular of satellite repeats, which is essential for cell cycle progression and proper chromosome segregation. Our results have pharmacological implications for cancer and autoimmune diseases characterized by unregulated transcription of satellite repeats.

RESUMO

An investigation of the German consumer organisation "Stiftung Warentest" in 2017 confirmed significant deficiencies in the information, advice and supply of incontinence care products received by urinary incontinence patients. The German Society of Urology (DGU) thereupon drafted and later published guidelines concerning the consultation of patients in the context of incontinence care. Important aspects of the consultation process include the determination of the type of incontinence as well as its severity, clinical examination, and advice regarding possible curative treatments. However, the advice appointment takes centre stage and should ideally be conducted by a qualified person in a separate room granting sufficient privacy and time. Furthermore, repeated supply of a selection of samples for differing degrees and types of incontinence, accommodating the patient's individual preferences and anatomical features, is crucial in order to ensure optimal incontinence care. In the case of commercial health care service providers, transparency relating to the financial implications of e.g. expensive products is key, which is what has been intended by German health insurance providers. The new guidelines concerning urinary incontinence care consultation constitute a step towards the improvement and structuring of processes in the consultation regarding, and the supply of, incontinence care products.

RESUMO

INTRODUCTION: A percutaneous nephrostomy (PCN) affects the integrity of the patient due to the requirement of an external drainage bag and regular changes. The catheter-associated quality of life (QOL) was evaluated using a validated assessment and compared to similar patients with suprapubic bladder drainage. METHODS: A validated assessment analyzing catheter-related QOL for 5 domains and 25 individual items (first published by Mary Wilde) was completed during a catheter change appointment by patients who had their unilateral or bilateral PCN for a minimum of 3 months in life-long indication. RESULTS: In 66 patients (unilateral PCN: 42 patients), a moderate impairment of their catheter-related QOL was shown. The overall QOL score was median 4.0 on a scale of 0-5. This was rated lower-indicating a stronger impairment of QOL-than in patients with a suprapubic bladder catheter, who had a median score of 4.3. Significant differences were found related to the catheter type in the items "feeling of humiliation due to the PCN", "conflicts with the medical or nursing staff", "fear of painful catheter changes", "feeling ill", "being handicapped in activities of daily living" and "concern of not being able to do what one wants to do" and "fear of catheter leakages". The indication for the PCN due to a malignant or benign underlying disease was not associated with the catheter-related QOL. CONCLUSION: For the first time, the catheter-related QOL was found to be moderately impaired in patients with a PCN using a validated assessment. Affected individuals report feeling "ill" and "limited/disabled" in activities of daily living; thus, the surgical indication should be strict. Fear of painful catheter changes and of catheter leakages indicates the need of technically correct catheter changes.

RESUMO

BACKGROUND: The insertion of a Foley catheter (FC) or a suprapubic catheter (SPC) in lifelong intent is an intervention with significant complications, comorbidities and impact on the further life that has not yet been analyzed. METHODOLOGY: The analysis was based on a validated assessment of catheter-related QoL with 25 items in 5 domains and applied to patients with a Foley or suprapubic catheter in lifelong indication and with the catheter in place for at least 3 months. Assessment data were enriched with information on the type and diameter of the catheter as well as demographic data. RESULTS: Questionnaires from 357 patients (260 male, 97 female, 193 with suprapubic catheter, 162 with Foley catheter, 2 no information) were included in the study. Patients with a Foley catheter were significantly older than patients with a suprapubic catheter (78.9 ± 11.1 years vs. 74.4. ± 12.6 years, p < 0.001). The average QoL score was 4.1 points on a scale from 1 (maximum impairment of QoL) to 5 (no impairment of QoL) indicating a moderately negative impact on QoL. Scores below the average were mainly driven and accompanied by a fear of urine leakage, urine odor, painful catheter changes and urinary infections increasing with age. Additionally, patients were worried about negative effects on their daily life activities due to the catheter. These worries seemed to be more pronounced in females with urinary incontinence, patients with a catheter size ≥ 18 Ch. and with an age of < 70 years. The type of catheter showed a greater impact on the QoL in females with suprapubic catheters when compared with males in contrast to patients with transurethral catheters. CONCLUSION: The results of the study provide further information for the medical clarification for patients and caregivers, having to decide between a lifelong catheter drainage or alternatives, such as provision of an aid or surgical recanalization.

RESUMO

BACKGROUND AND AIMS: The aim of this randomized trial in the acute porcine model was to compare the quality of transgastric peritoneoscopy with the use of low-pressure versus standard-pressure pneumoperitoneum and to evaluate the respective associated cardiopulmonary changes. METHODS: For transgastric peritoneoscopy, carbon dioxide was insufflated via the endoscope for a constant intraperitoneal pressure of 6 mmHg or 12 mmHg in 9 pigs each. The quality of transgastric peritoneoscopy was rated on a visual analog scale (0 mm, min.; 100 mm, max.) by the endoscopist, who was blinded to the intraperitoneal pressure. The cardiac index and global end-diastolic volume index (GEDVI, reflecting preload) were measured every 3 minutes by transpulmonary thermodilution. The following were also recorded: heart rate, mean arterial pressure (MAP), systemic vascular resistance index (SVRI, reflecting afterload), peak inspiratory pressure (PIP), pH, PCO (2), and PO (2). RESULTS: The quality of transgastric peritoneoscopy with the use of low-pressure pneumoperitoneum was not inferior to that obtained using standard-pressure pneumoperitoneum (87.0 mm vs. 87.3 mm; P<0.05). In both groups we observed a statistically significant rise in MAP and SVRI. The increase in SVRI was less pronounced during low-pressure peritoneum ( P=0.042), indicating a reduced stress response in comparison to standard-pressure peritoneum. There were no relevant differences between the groups in relation to cardiac index, GEDVI, and heart rate. An intra-abdominal pressure of 6 mmHg also led to better oxygenation ( P=0.031 for difference in PO (2) between the two groups) due to lower peak inspiratory pressure ( P<0.001 for difference). There were only slight differences between the groups with regard to pH and PCO (2). CONCLUSIONS: Pneumoperitoneum of 12-16 mmHg is used for standard laparoscopy. For NOTES, low-pressure pneumoperitoneum is sufficient and is associated with an improved cardiopulmonary response compared to standard-pressure pneumoperitoneum.

RESUMO

OBJECTIVE: The aim of this study was to determine the predictive value of the anatomical location of positive prostate biopsies for the nodal status of patients with localized prostate cancer. METHODS: A total of 130 patients were included in this analysis. Prior to surgery, all patients underwent digital rectal examination (DRE), prostate-specific antigen (PSA) analysis and transrectal ultrasonography with systematic sextant biopsies. Each biopsy core was analyzed separately. Subsequently, all patients underwent pelvic lymphadenectomy and radical retropubic prostatectomy. The final pathological stage was correlated with the number of anatomical location of positive prostate biopsies. RESULTS: Eighteen patients (13.8%) had positive lymph nodes. Based on clinical stage, serum PSA and the anatomical location of positive prostate biopsies, a staging model was developed with particular emphasis on the nodal status. In group I (n = 33; 25.4%), defined by negative basal biopsies and clinical stage T2 (irrespective of PSA), all patients had negative lymph nodes. Similarly, all but 1 patient were lymph node negative in group II (n = 36; 27.7%), which included cases of positive basal biopsy, PSA < 10 ng/ml clinical T2. Finally, group III (n = 61; 46.9%), defined by a positive basal biopsy and/or PSA > 10 ng/ml and/or clinical T3 included 17/18 (94.4%) node-positive patients. CONCLUSION: Based on these data we consider it safe not to perform lymphadenectomy in group I and group II patients as only 1/69 patients (1.4%) was node positive. Patients meeting the group III criteria, however, should undergo pelvic lymphadenectomy, as 94.5% of all lymph-node-positive cases were in this group.

RESUMO

Our experiences with the continent urinary diversion and the bladder substitution by means of the Mainz-Pouch technique are reported. We were one of the first Urological Departments in Austria to introduce this technique in late 1987. We present the operative technique, the patient material of 15 patients and their outcome with early and late complications over a follow up period of 16.6 months.

RESUMO

After a 4 years experience with the conventional retropubic operative free-hand technique the implantation procedure has been modified. For local therapy the volume of the prostate is measured endosonographically and biopsies are taken from defined areas of the prostate under transrectal ultrasonographic guidance using a puncture attachment (prostate mapping). According to the data of volumetry and pathology the brachytherapist calculates number and precise location of the seeds, which are inserted in a second procedure after diagnostic lymphadenectomy percutaneously and transperineally under ultrasonographic guidance with a afterloading technique. Since 1984 24 patients has been treated in this manner. Implantation procedure is described, preliminary clinical results are presented and the percutaneous technique is compared with the retropubic operative approach. The percutaneous, transperineal and ultrasonically guided 125Iodine implantation represents an alternative procedure to the radical prostatectomy and gives a good local tumor control in prostatic carcinoma with minimal side effects.
