Die Patientenaufklärung zur Prostatakarzinomfrüherkennung ist unzureichend

Men that undergo an early detection investigation should be informed of the advantages and disadvantages as well as of the therapeutic consequences. In this study the quality of information was checked using the state of scientific knowledge of the patients.An informative consultation was carried out before the early detection investigation using a clarification brochure and an examination by a urologist. A questionnaire was also filled out after the investigation. A total of 1,536 men were questioned. Although 47% of the men had previously undertaken a PSA at least once, only 55% knew their own test result. Subjectively 82% of men felt well informed. In contrast one-third did not know the significance of an increased PSA level. In the field of patient clarification for the early detection for prostate cancer there are considerable deficits but the information received was considered adequate by the participants. However, more than one-third did not understand the significance of the PSA level.

Wie sollen Urologen venöse subkutane Portsysteme implantieren

BACKGROUND Since 1999 urologists at the University of Essen in Germany have performed subcutaneous implantation of venous port systems, controlled by intravasal ECG. METHODS Between December 1999 and June 2011 implantation of venous port systems was performed in 241 male (69.5%) and 106 (30.5%) female patients. The port systems were implanted subcutaneously above the pectoralis major muscle under local anesthesia. If it was not possible to isolate the cephalic vein or safe catheter implantation was not feasible, puncture of the subclavian vein was performed. RESULTS The median follow-up was 491.6 days (2-2568), and 163.254 catheter days (mean 239 days, range 2-2604) were documented. During the follow-up period 191 (55.1%) patients died. The mean surgical implantation and explantation time was 36.5 min (14-85 min) and 25.4 min (10-46 min), respectively; 79.7% were implanted and controlled by ECG. Altogether, 390 devices were used in 379 surgical procedures, 355 implantations (91.1%) and 35 explantations (8.9%). Implanted vessels were the cephalic vein in 303 patients (85.6%) and the subclavian vein in 51 (14.4%) patients. Of 35 explanted devices, the explantation was necessary due to complications in 28 (8.0%) cases: infection n=6 (1.7%, 0.036 per 1,000 catheter days), occlusion n=8 (2.3%, 0.049 per 1,000 catheter days), dislocation n=7 (2.0%, 0.042 per 1,000 catheter days), deep vein thrombosis of the upper extremity n=6 (1.7%, 0.037 per 1,000 catheter days), and clotting n=1(0.3%, 0.006 per 1,000 catheter days). Premature catheter removal (<30 days post-op) was required in six cases (1.9%, 0.036 per 1,000 catheter days) due to complications: three catheter dislocations/malfunctions (0.9%, 0.019 per 1,000 catheter days), one port-related infection, one pocket port infection, and one deep vein thrombosis of the upper extremity (0.3%, 0.006 per 1,000 catheter days). Other problems described in the literature like pneumothorax, vein perforation, or pinch-off syndrome did not occur. CONCLUSIONS Implantation of port systems with ECG control of the catheter tip position is related to a few cases of adverse events and good surgical outcomes. Furthermore, it has also shown great advantages in offering immediate support and early therapy initiation with a fast learning curve for the training urologists. The results of the presented analysis are comparable to those of surgical or radiological departments reported in the literature and provide good evidence that this procedure should be extended to urological centers with a high volume of chemotherapy patients.

Vergleich der perioperativen Methylenblau-gefärbten Schnellzytologie mit der nach Papanicolaou gefärbten Permanentzytologie in der Detektion von Patienten mit High-grade-Urothelkarzinomen der Harnblase

INTRODUCTION The aim of the study was to investigate whether intraoperative methylene blue-stained and permanent Papanicolaou-stained urine cytologies show comparable accuracy in detection of high-grade urothelial carcinoma. PATIENTS AND METHODS The study included 130 patients; 50 patients were without malignancy (25 follow-up, 25 with hematuria). In 80 patients transurethral resection due to urothelial carcinoma was performed. Per patient two cytology specimens were prepared: one immediate methylene blue-stained specimen, which was evaluated by the surgeon, and one Papanicolaou-stained permanent cytology slide, which was blinded and evaluated by one urologist. RESULTS Cytology results of all patients without malignancy were unsuspicious irrespective of the staining method. Of 80 patients with urothelial carcinoma, 50 showed a low-grade tumor. Sensitivity of tumor detection was 20 and 30% for methylene blue/Papanicolaou-stained slides, respectively. Among 30 patients with high-grade carcinoma, 10 were detected by methylene blue cytology and 30 by Papanicolaou-stained slides, corresponding to a sensitivity of 40 and 100%, respectively. CONCLUSIONS The results of standard Papanicolaou-stained urine cytology in the detection of clinically relevant high-grade urothelial carcinoma are excellent. The quality of cytological tumor detection by methylene blue-stained cytology made by different evaluators is insufficient in our opinion.

Die gestielte Vorhautlappenplastik@@@Pedicled prepuce flap plasty: Ergebnisse bei Patienten mit Hypospadie oder Harnröhrenstriktur@@@Results in patients with hypospadias or urethral sticture

BACKGROUND Operative interventions of the urethra remain challenging procedures. The vascular onlay flap of the inner prepuce is a possible technique for short and long segment urethral defects. PATIENTS AND METHODS A total of 195 patients were surgically treated with a vascular prepuce flap between 1994 and 2010 at the Urology Department of Essen Medical University. Patient data were analyzed retrospectively and a questionnaire was sent to all patients. RESULTS Of the patients 115 answered the questionnaires and were included in the study. Of these 61 patients were treated in childhood due to hypospadias and 54 patients suffered from acquired urethral stricture. Major complications were postoperative fistulas in 8.2 % and 7.4 % and hematomas in 6.6 % and 11.1 % of cases, respectively. Operative revision had to be performed in 13.1 % and 14.8 % of cases and severe obstructive micturition problems (IPSS score ≥ 20) were observed in only 3.3 % and 11.1% of patients, respectively. Subjective overall satisfaction with the result of the operation was high (67.2 % and 88.9 %, respectively). CONCLUSION The vascular prepuce flap is a reliable method for correction of short and long segment urethral defects and is associated with high patient satisfaction.

[Failure to attend appointments: data analysis of a urological group practice over 12 months].

PURPOSE A well-structured system of appointments is mandatory in urological practices to provide a perfect work flow. A huge problem is appointments which are not cancelled by non-attending patients and remain free during consultation hours. METHODS An analysis of the electronic calendar of our group practice was performed from January 2010 to December 2010. RESULTS In 2010, 24,764 appointments in consultation hours were scheduled and of those 1,348 (5.4%) were not cancelled but not attended by the patients. Out of 1,760 X-ray investigations 59 (3.3%) patients did not show up and of 3,828 cystoscopy appointments, 109 (2.8%) patients did not cancel although they did not attend. A total of 440 outpatient appointments for surgery were scheduled and 8 (1.8%) patients did not attend but did not cancel surgery. Out of 176 (11.4%) scheduled spermiogram appointments, 20 patients did not bring a sample for analysis. CONCLUSIONS Due to the experiences of the authors, combined investigations, e.g. intravenous pyelogram (IVP) and cystoscopy on one day, should therefore be avoided in order to be able to cancel the second appointment when patients do not show up for the first appointment. In cases of surgical interventions, patients should be contacted by telephone 2-3 days prior to surgery for confirmation. Currently under German law there is no way to claim compensation for missed appointments from the patients. Thus, the only way to avoid large numbers of missed appointments is to keep those as low as possible, as soon as appointments are made and scheduled (e.g. no double appointments).
