[Acceptance and status of digitalization in clinics and practices : Current assessment in German urology]. / Akzeptanz und Stand der Digitalisierung in Klinik und Praxis : Aktuelles Stimmungsbild in der deutschen Urologie.

BACKGROUND: Digitalization of patient documentation and introduction of the electronic patient record (ePA) pose challenges to everyday clinical practice. OBJECTIVES: We investigated the acceptance and status of the digitalization of patient data and the introduction of the ePA among German urologists. MATERIALS AND METHODS: A questionnaire with 30 questions about the acceptance and status of digitalization of patient documentation and ePA was sent out via the newsletter of the German Society of Urology. RESULTS: A total of 80 urologists participated in the survey (response rate 2%). Digital platforms such as Urotube or Researchgate are used by 63% of participants. The complete implementation of digital patient documentation was reported by 72% of respondents working in medical practice and by 54% of those working in the hospital (p = 0.042). While 76% see the digitalization process as reasonable, 34% expressed partial or strong concerns about the complete digitalization of patient documentation. Only 14% of the participants offer video consultations. Advantages for ePA include better networking of the healthcare system (73%), improved diagnosis, indication (41%) and treatment quality (48%), and avoidance of medication errors (70%). CONCLUSION: German urologists are open to the digitalization process and ePA. Especially younger urologists are using digital media. The advantages of digitalization are, in particular, an improvement in treatment processes. For a smooth introduction, a cross-departmental establishment and, if necessary, an adaptation of the treatment processes are necessary.

Diagnostic value of magnetic resonance imaging in Peyronie's disease--a comparison both with palpation and ultrasound in the evaluation of plaque formation.

OBJECTIVE: To compare the value of magnetic resonance imaging (MRI) with palpation and ultrasound in the evaluation of plaque formation in Peyronie's disease. METHODS: 57 patients underwent a standardized diagnostic procedure to evaluate plaque formation consisting of palpation and ultrasonography (7.5 MHz). MRI was performed during flaccidity and during erection induced by Prostaglandin E(1) including intravenous application of Gadolinium-diethylenetriaminepentaacetic acid (Gd-DPTA). RESULTS: With all methods, 93 plaques have been detected in 57 patients. 85 plaques (91.4%) have been evaluated by palpation alone. Using ultrasound, 52 of these 93 plaques (55.9%) were detectable. This is equivalent to 61.1% of the palpable plaques. MRI confirmed 58 of the palpated plaques (68.2%) and exposed 8 primarily not palpable plaques at the penile basis. MRI revealed more palpable plaques than ultrasound, but this finding was not significant (p = 0.083). By means of sonography, calcification was evident in 14 plaques. MRI failed in revealing any calcification. After application of Gd-DPTA, 5 of 57 patients (9%) demonstrated contrast enhancement indicating local inflammation. None of these patients reported on penile pain. CONCLUSIONS: Penile palpation in combination with ultrasound represents the method of choice to diagnose plaque formation in Peyronie's disease. MRI provides better information on plaque formation at the penile basis. Calcification can only be proven by ultrasound, not by MRI. There may be additional information by MRI about local inflammation. A prospective study comparing the histological and MRI findings should be performed to answer the question, if pain is really associated with inflammation.

Serum levels of inhibin B and follicle-stimulating hormone may predict successful sperm retrieval in men with azoospermia who are undergoing testicular sperm extraction.

To evaluate the predictive power for sperm retrieval in testicular sperm extraction of inhibin B and FSH levels in the peripheral blood in association with the testicular histology. Clinical study. Departments of andrology and urology at a university hospital.Fifty-two patients with azoospermia. Determination of serum levels of FSH and inhibin B in men with azoospermia. Testicular incision and histological investigation as well as testicular sperm extraction (TESE) followed by intracytoplasmic sperm injection were performed. Comparison of hormone levels with different histological features of seminiferous tubules (normospermatogenesis, hypospermatogenesis, and Sertoli cell-only syndrome) and TESE outcome.With respect to the histological proof of spermatozoa, the sensitivity of the FSH levels >10 mU/mL was 82%, and of inhibin B levels, <79 pg/mL, 78%; the specificity was 80% for both hormone levels. With respect to the successful sperm extraction in the TESE procedure, the sensitivity of the FSH levels was 58% and the specificity was 50%; and the sensitivity of inhibin B levels was 52.5% and the specificity was 60%. Inhibin B and FSH levels are correlated with spermatogenetic activity. The combination of the two parameters is currently the best predictor for the presence of sperm, which may be found in TESE. However, the prediction is not absolutely reliable: TESE can be also successful when both hormone levels are outside the threshold levels.

Long-term results of plaque thinning with carbide burs, small incisions and venous grafting for correcting complex penile curvature in Peyronie's disease: poor results of an "ideal" approach.

PURPOSE: We evaluated the long-term results of plaque thinning by carbide burs, small transverse incisions and venous grafting for correcting complex penile curvature in patients with Peyronie's disease. MATERIALS AND METHODS: A total of 13 patients with Peyronie's disease and complex penile curvature received plaque thinning by carbide burs equipped with a fraise, small plaque incision and venous grafting. All patients were available for long-term followup at a mean of 29 months. Preoperatively the mean dorsal curvature angle was 73 degrees with an additional malrotation in 4 patients. Followup consisted of a standardized interview and 3-dimensional photo documentation during erection. RESULTS: Although penile straightening was achieved intraoperatively, dorsal curvature (mean 35 degrees) recurred in 8 men, of whom 3 noticed this deterioration after a longer period. Penile shortening (mean 3.3 cm.) occurred in 7 patients, and decreased rigidity during intercourse occurred in 4. CONCLUSIONS: Hypothetically, a combined technique of thinning, incision and grafting seems to be an ideal surgical approach for correction of complex penile curvatures in Peyronie's disease without plaque excision. Although the penis had been completely straightened intraoperatively, severe dorsal curvatures recurred and significant penile shortening became obvious in more than half of the patients. Manipulation of the plaque may be associated with activation of the disease, with all of the risks of recurrence and deterioration. Due to the poor results of the thinning procedures, we stopped using this surgical approach and now prefer a combination of small incisions and grafting only.
