[Use of synthetic slings and mesh implants in the treatment of female stress urinary incontinence and prolapse : Statement of the Working Group on Urological Functional Diagnostics and Female Urology of the Academy of the German Society of Urology]. / Einsatz von synthetischen Band- und Netzimplantaten bei der Behandlung von Belastungsinkontinenz und Descensus genitalis der Frau : Stellungnahme des Arbeitskreises Urologische Funktionsdiagnostik und Urologie der Frau der Akademie der Deutschen Gesellschaft für Urologie.

Due to a safety alert issued by the US Food and Drug Administration (FDA) in 2011 for transvaginal mesh implants to treat female prolapse as a result of numerous reports of complications such as infection, chronic pain, dyspareunia, vaginal erosion, shrinkage and erosion into other organs nearly all industrial products have been withdrawn from the market in the meantime. The United Kingdom, Australia, and New Zealand extended warnings and prohibitions even on the implantation of midurethral slings (TVT, TOT). In view of these current international controversies regarding the use of implanted materials for the treatment of stress incontinence and prolapse and the lack of clear guidelines for the use of biomaterials, the opinion of the Working Group on Urological Functional Diagnostics and Female Urology should provide clarity. The Opinion is based on the SCENIHR Report of the "European Commission's Scientific Committee on Emerging and Newly Identified Health Risks", the "Consensus Statement of the European Urology Association and the European Urogynaecological Association on the Use of Implanted Materials for Treating Pelvic Organ Prolapse and Stress Urinary Incontinence" and in compliance with relevant EAU and national guidelines and the opinion of the Association for Urogynaecology and Plastic Pelvic Floor Reconstruction (AGUB eV). In addition, recommendations are given for the future handling of implants of slings and meshes for the treatment of stress incontinence and prolapse from a urologic viewpoint.

[Suburethral tension-free vaginal tape or transobturator tape. When should which procedure be recommended?]. / Suburethrale Bänder TVT und TOT. Welches Verfahren ist wann empfehlenswert?

The introduction of tension-free vaginal tapes has led to a complete change of surgical therapy in female urinary stress incontinence. Different materials are used. In many departments, the classic TVT procedure with retropubic placement of the tape has been replaced by transobturator procedures. The current discussion involving transobturator tapes focuses on the question of whether the inside-out technique or the outside-in technique leads to significantly different results. Current state of the art is that all techniques are almost comparable concerning treatment success and complications. Depending on possible pretreatments or concomitant diseases that result in a higher risk for complications, the decision for one technique can be taken individually for each patient. In patients suffering from recurrent stress urinary incontinence after implantation of a tension-free tape, the retropubic implantation of a TVT seems to be superior to a transobturator tape.

[Stress incontinence in women. Is there still an indication to perform the Burch colposuspension and the fascial sling procedure?]. / Belastungsinkontinenz der Frau. Gibt es noch eine Indikation zur Burch-Kolposuspension und zur Faszienzügelplastik?

Open Burch colposuspension has been the gold standard for many years in therapy for stress urinary incontinence and still has a major position in this field by virtue of its excellent long-term results. Tension-free transvaginal tapes nowadays also achieve the same success rates and replace the Burch operation due to less invasiveness of the procedure (1). Burch colposuspension is still used in cases of recurrence and as a combination procedure for stress urinary incontinence and vaginal prolapse. The laparoscopic Burch procedure has been increasingly performed in recent years.Fascial sling procedures are used primarily for recurrence of female stress urinary incontinence and intrinsic sphincter deficiency. The treatment principle is based on repositioning both the urethra when it has descended and the bladder neck as well as increasing the reduced outlet resistance. This approach is still employed today to treat stress urinary incontinence in women.

[New techniques for surgical treatment of postoperative male stress incontinence]. / Neue Verfahren zur operativen Therapie der postoperativen Belastungsinkontinenz beim Mann.

The impact of minimally invasive techniques for the treatment of postoperative male incontinence has significantly improved in recent years. These techniques are based on the continuous increase in urethral resistance. This resistance can be readjusted with balloons placed paraurethrally or with readjustable suburethral slings. The success rates depend on the preoperative degree of incontinence. With bulking agents that are transurethrally injected into the submucosa of the sphincter, continence rates between 12 and 90% can be seen. Severe complications are rare. The impact of the studies is often limited due to a short follow-up. After implantation of adjustable balloons that are placed paraurethrally close to the bladder neck, continence rates up to 70% can be seen. The overall improvement of incontinence is observed in up to 90% of the treated patients. Complications such as balloon migration or mechanical disorders can cause operative revision. Suburethral sling systems are available as bone-anchored slings or as readjustable slings. Continence can be seen in up to 90% of the patients postoperatively. Severe complications such as sling erosion or sling infection are rare. In cases of mild and moderate incontinence, these minimally invasive techniques are good alternatives to the fascial sling or alloplastic sphincter implantation. To improve the evaluation and to compare these techniques with the conventional methods, further investigations with a longer follow-up are necessary.

[The role of perineal ultrasound compared to lateral cysturethrogram in urogynecological evaluations]. / Die Perinealsonographie im Vergleich zum lateralen Zysturethrogramm bei der Inkontinenzdiagnostik der Frau.

PURPOSE: The aim of this study was to evaluate prospectively whether perineal ultrasound is comparable to the lateral cysturethrogram in the evaluation of incontinent women. PATIENTS AND METHODS: Following urodynamic investigations, a lateral cysturethrogram and perineal ultrasound (5 MHz probe, bladder filling 300 mL) were performed in 98 incontinent women. In women with detrusor overactivity and consecutively reduced bladder capacity, ultrasound was performed at maximum capacity. To evaluate differences between perineal ultrasound and the cysturethrogram, the difference between bladder neck and lower border of symphysis and the retrovesicle angle beta were determined at rest and during the Valsalva manoeuvre. RESULTS: Using perineal ultrasound, the differences between bladder neck and symphysis could be determined at rest and during the Valsalva manoeuvre in all patients. The determination of the retrovesical angle beta was possible in all patients at rest and in 89 of the 98 women during the Valsalva manoeuvre. The lateral cysturethrogram enabled the determination of difference between bladder neck and symphysis and the retrovesicle angle beta at rest in 81 of 98 women. During the Valsalva manoeuvre, the difference between bladder neck and symphysis and retrovesicle angle beta could be determined in 72 of the 98 women. In the 26 remaining women, the determination was impossible due to severe adiposity or cystoceles of the second or third degree. CONCLUSIONS: Perineal ultrasound provides comparable data to the lateral cysturethrogram. In patients with adiposity, perineal ultrasound seems to be superior. Within the routine evaluation of women suffering from incontinence, the lateral cysturethrogram can be replaced by perineal ultrasound without any limitations of the diagnostic value.

[Wolfgang Amadeus Mozart. A urological pathography]. / Wolfgang Amadeus Mozart. Eine urologische Pathographie.

The death of Wolfgang Amadeus Mozart was mysterious from the very first day, and cause of wildest speculation and adventurous assertions. Over the last 100 years, medical science has investigated the physical sufferings and the mysterious death of Mozart with increasing intensity. By means of letters from his father Leopold, his sister "Nannerl", himself and reports from his physicians and contemporaries, we would like to create a medical pathography. The rumour that Mozart was poisoned appeared soon after his early death at the age of 35 on December 5th 1791, and was kept up persistently. Accused were the physician van Swieten, Mozart's freemason's loge and the royal band master Salieri. Mozart, however, died due to chronic kidney disease and ultimately due to uraemia. Once the renal damage has reached a certain point, a minimum of additional stress leads to decompensation. This catastrophe occurs typically within the fourth decade of life. When listening to Mozart's music, we should remember that this apparently happy person was actually a premature adult robbed of his childhood, whose short life was an endless chain of indisposition, over fatigue, misery, concern and illness.

[Indication for urodynamic testing]. / Indikationen zur urodynamischen Untersuchung.

BACKGROUND: The aim of urodynamic testing is to obtain objective information regarding urinary bladder storage and voiding function. Basic investigations provide information of the underlying incontinence form. Depending on the individual situation and findings, further urodynamic investigations are helpful or indicated. Prior to conservative therapy, a routine urodynamic investigation is not indicated. OBJECTIVES: Due to limited evidence of preoperative urodynamic investigations on postoperative results, the urodynamic results may be helpful when considering various treatment options. RESULTS: Urodynamic investigations should be performed preoperatively, especially in case of overactive bladder symptoms, prior incontinence surgery, or disordered bladder emptying. The assessment of urethral function should be considered in the urodynamic investigation of stress urinary incontinence. In patients with pelvic prolapse, urodynamic investigations should be performed during prolapse reposition.

Sacral anterior root stimulation and posterior rhizotomy in spastic neuropathic bladder.

The combination of sacral anterior root stimulation (SARS) and posterior rhizotomy is a successful procedure for the restoration of bladder function after supraconal spinal cord injury. Today, complete posterior rhizotomy has become part of the standard therapy. Conventional SARS leads to simultaneous activation of both the detrusor muscle and the external urethral sphincter. We evaluated the possibilities of different neurostimulation techniques to overcome stimulation-induced detrusor-sphincter-dyssynergia and to achieve physiological voiding. Selective detrusor activation improves current sacral neurostimulation of the bladder, including the “poststimulus voiding” principle. Selec-tive neurostimulation is possible in the following techniques: anodal block, high-frequency block, depolarizing prepulses, sinusoidal pulses and cryoblock. The anodal block technique and cryotechnique are excellent methods for selective bladder activation to avoid detrusor-sphinc-ter-dyssynergia and thus improve stimulation-induced voiding. Our experience has shown that future modern selective bladder neurostimulation systems will be based on either the anodal block technique or the cryotechnique.

Intracavernous administration of SIN-1+VIP in an in vivo rabbit model for erectile function.

In accordance with the data reporting the identification of nitric oxide synthase (NOS) and vasoactive intestinal polypeptide (VIP) positive nerve fibres in the trabecular meshwork of the corpus cavernosum, we suggest that nitric oxide (NO) and VIP may serve complementary physiological roles in penile erection. Therefore SIN-1 and VIP were administered alone and in combination in an in vivo rabbit model. All rabbits revealed basal pressure values of 5-8 cm H2O intracavernously. In the rabbits intracavernously (i.c.) injected with SIN-1 alone and VIP alone, no adequate erectile responses were observed. Whereas, in the group intracavernously injected with the combination of SIN-1+VIP, erectile responses with mean maximal intracavernous pressure (max. ICP) 52.8 (+/-13.2) cm H2O were noted. These pressure elevations do not statistically diverge (P>0.05) than the ones obtained in the control group administered i.c. injections of the combination of papaverine/phentolamine (mean max. ICP 51 (+/-14.73) cm H2O). Referring to our results, we conclude that the combined use of SIN-1+VIP could play an important role in the physiological treatment of erectile dysfunction.

Restoration of bladder function in spastic neuropathic bladder using sacral deafferentation and different techniques of neurostimulation.

PURPOSE: Conventional sacral anterior root stimulation (SARS) results in simultaneous activation of both the detrusor muscle and the external urethral sphincter. We evaluated the possibilities of different neurostimulation techniques to overcome stimulation induced detrusor-sphincter-dyssynergia and to achieve a physiological voiding. MATERIAL AND METHODS: The literature was reviewed on different techniques of sacral anterior root stimulation of the bladder and the significance of posterior rhizotomy in patients with supraconal spinal cord injury suffering from the loss of voluntary bladder control, detrusor hyperreflexia and sphincter spasm. RESULTS: The achievement of selective detrusor activation would improve current sacral neurostimulation of the bladder, including the principle of "poststimulus voiding". This is possible with the application of selective neurostimulation in techniques of anodal block, high frequency block, depolarizing prepulses and cold block. Nowadays, sacral deafferentation is a standard therapy in combination with neurostimulation of the bladder because in conclusion advantages of complete rhizotomy predominate. CONCLUSIONS: The combination of sacral anterior root stimulation and sacral deafferentation is a successful procedure for restoration of bladder function in patients with supraconal spinal cord injury. Anodal block technique and cryotechnique are excellent methods for selective bladder activation to avoid detrusor-sphincter-dyssynergia and thus improve stimulation induced voiding.

Sacral anterior root stimulation and cryotechnique: A new option for selective urethral sphincter block and reversible deafferentation in the future?

A possible application of cryotechnique might be a selective block of nerve fiber activity during sacral anterior root stimulation to achieve selective block of urethral sphincter and reversible deafferentation. In 13 foxhounds, electrical stimulation of sacral anterior roots S2 was performed while the accompanying spinal nerves were simultaneously cooled down from +25 degrees C in a stepwise fashion until a block of urethral sphincter activity was observed. The effects of cold block on the urethral sphincter and bladder were monitored by urodynamic investigation. In 2 additional dogs sacral posterior roots S2 were cooled down to +3 degrees C while accompanying anterior and posterior roots were stimulated distal to the cryothermode. Compound action potentials (APs) were registered proximal to the cryothermode before, during and after cooling and recovery time of cold blocked nerves was evaluated. Complete cold block of the urethral sphincter during spinal nerve cooling was achieved in all cases. Block temperature averaged +12 degrees C. Detrusor pressure was a mean 5,2 cm water. Recovery time was on average 5 min. The cold block was always reversible. In both dogs of the second series the compound action potentials disappeared nearly completely at +3 degrees C. Three min after the end of the cooling period the appearance of the compound action potentials was back to normal. In this study, cryotechnique proved to be effective for selective and reversible block of nerve fibers during sacral anterior root stimulation. In functional electrical stimulation this technique may lead to an improvement of quality of life in para- or tetraplegic patients resulting in optimization of voiding, standing, walking and grasping and does so without the necessity of surgical dorsal root rhizotomy.

[Sacral neuromodulation in treatment of functional disorders of the lower urinary tract. An overview of basic principles, indications, outcomes]. / Sakrale Neuromodulation in der Behandlung von Funktionsstörungen des unteren Harntrakts. Ein Uberblick über Prinzip, Indikationen und Ergebnisse.

Over the last few years, sacral neuromodulation has become an established treatment option for dysfunctions of the lower urinary tract. It fills the gap that used to exist between conservative therapy and costly invasive methods such as urinary drainage via a deactivated bowel segment. Initially, the clinical value of sacral neuromodulation was controversial even among neurourologists. This was mainly due to a lack of understanding of the physiological processes, uncertain diagnostics, the design of the hardware, and a surgical topography relatively unknown to the urologist. In the meantime, however, sacral neuromodulation has become a standard part of clinical routine with respect to the treatment of dysfunctions of the lower urinary tract, and it is regularly employed in various urological institutions across Europe and the USA. This form of treatment, which is the final straw for patients who believed themselves-after many frustrated therapy attempts-to be "hopeless cases," can now also successfully be employed as an ambulatory measure. The latest data from our hospital, as well as contributions presented at the last DGU Congress in Wiesbaden, indicate that patients with neurogenic urinary retention are the most likely to profit from this treatment option.

[Volumetry of the urinary bladder with implantable ultrasound sensors]. / Volumetrie der Harnblase mittels implantierbaren Ultraschallsensoren.

Experimental studies revealed that the contractile response of the urinary bladder to sacral anterior root stimulation depends on the actual bladder volume. Furthermore, no clinical relevant technique is available for continuous monitoring of the bladder wall distension respectively bladder volume in paraplegic patients. The presented study investigates the reliability of especially developed implantable ultrasound sensors as a sensoric system for continuous monitoring of the bladder volume. In six anaesthesized pigs two ultrasound sensors, one transmitter and one receiver, were implanted on the bladder wall at different locations (latero-lateral, dorsal-ventral, rostral-caudal). After closing the abdominal wall, the bladder was filled in 50 ml steps up to 250 ml. After each filling step the running time of the ultrasound signal was measured. In all experiments reproducible results and a high correlation of the measured running times with bladder volume were observed. The latero-lateral configuration of the sensors seemed to be most confidential. The presented study indicates that bladder volumetry with implantable ultrasound sensors is possible with minimal technical prerequisites. This promising technique for continuous bladder volumetry could play an important role in the development of an intelligent and autoadaptive neurostimulator of the urinary bladder in paraplegic patients.

[Chronic sacral bilateral neuromodulation. Using a minimal invasive implantation technique in patients with disorders of bladder function]. / Chronische sakrale bilaterale Neuromodulation. Einsatz einer minimalinvasiven Implantationstechnik bei Patienten mit Blasenfunktionsstörungen.

The implantable neuromodulation system described by Tanagho and Schmidt enables unilateral sacral nerve stimulation. Reports have been made on sacral neuromodulation failures of up to 50% in patients undergoing this procedure. We chose the bilateral electrode implantation and a minimal invasive laminectomy to ensure a more effective modulation and better placement and fixation of the electrodes. After successful assessment using a peripheral nerve evaluation test, 20 patients (14 with detrusor instability, 6 with hypocontractile detrusor) underwent minimally invasive laminectomy and bilateral electrode placement. In the patients with detrusor instability, the incontinence episodes were reduced from 7.2 to 1 per day and the bladder capacity improved from 198 to 352 ml. In patients with hypocontractile detrusor, the initial residual urine level of 450 ml dropped to 108 ml. Maximum detrusor pressure during micturition rose from 12 cmH2O initially to 34 cmH2O. The average follow up period was 17.5 months. There was no sign of deterioration in the modulation effect in any of the patients. Bilateral electrode implantation and the new sacral approach allow optimal neuromodulation in patients with bladder dysfunction. Laminectomy enables optimum electrode placement and fixation with minimal trauma.

[Clinical Results of PNE Tests in 70 Patients with Different Bladder Dysfunctions]. / Klinische Ergebnisse nach 70 bilateralen peripheren Nerven-Evaluationstests (PNE-Test) bei Patienten mit Harnblasendysfunktionen.

PURPOSE: Prior to implantation of a sacral neuromodulator we carried out PNE tests (peripheral nerve evaluation test) with bilateral test stimulation to establish which patients might profit from this kind of therapy. In contrast to the original unilateral technique used by Tanagho and Schmidt, we performed bilateral PNE test stimulation. Moreover, we analysed the diagnostic characteristics of those patients who had positive PNE test results and could thus receive a chronic sacral neuromodulator. MATERIALS AND METHODS: We performed bilateral PNE test stimulation in 70 patients (mean age: 53.6 yrs; 41 with retention symptoms and 29 with a hyperactive detrusor) over a minimum of 3 days. Retrospectively, we analysed the distribution of diagnostic characteristics (retention vs. overactive bladder and neurogenic vs. idiopathic) in the implant recipients. RESULTS: All patients received bilateral PNE test stimulation, during which the stimulation amplitudes were adjusted individually for each side. 8 patients were treated with the original PNE-electrode (model 0 041 830 - 002, Medtronic Inc., USA) without success. Of the remaining 62 patients, who were treated with an improved electrode, the PNE test was successful in 32 cases (51.6 %). Twenty-seven of these patients suffered from a neurogenic bladder dysfunction, and, in 5 cases, the causes were idiopathic. CONCLUSIONS: Bilateral PNE-test stimulation and the use of advanced PNE electrodes (model 3057, Medtronic Inc., USA) led to a positive PNE result in 51.6 % of the tested patients. Of these, the group with neurogenic bladder dysfunctions showed the highest response rate. Compared with the success rates in the multicenter study, we were able to increase the overall PNE response rate significantly. For this reason, we prefer a bilateral PNE-test with side-specific stimulation.

[Long-term follow-up of interstitial laser coagulation in the treatment of benign prostatic hyperplasia]. / Langzeitergebnisse der interstitiellen Laserkoagulation zur Behandlung der benignen Prostatahyperplasie.

INTRODUCTION: Besides standard open or transurethreal adenoma resection, less morbid interstitial laser coagulation (ILC) is an alternative therapeutical option that could reduce lower urinary tract symptoms, especially in high-risk patients. Although short-term results indicate effectiveness, reliable long-term statistics are still lacking. Therefore, to assess long-term satisfaction and overall success rate, we re-evaluated patients with a mean follow-up of 7 years after laser treatment. METHODS: A total of 72 patients had been included in our ILC programme between 1993 and 1995. Mean age was 74 years. About 45 % of the patients had since died of other causes. In all, 23 patients were evaluated by telephone questionnaire, International Prostate Symptom Score (IPSS), Quality of Life (QoL), second surgical interventions or medical therapy. Our patient group was treated with interstitial Nd:YAG laser coagulation (mediLas fibertom). A perineal (34 %), transurethral (23 %) or combined (43 %) approach was chosen, depending on the preoperative volume of the prostate (range 40 - 100 ml; mean 59.3 ml). RESULTS: 68.4 % of the patients were satisfied with their current urological situation. Mean IPSS was 8.8 vs. 18.8 preoperatively mean QoL 1.5 vs. 3.3. 15.8 % had undergone conventional transurethral prostatic resection in the interim; one patient uses a urine catheter. 15.8 % receive medical treatment for lower urinary tract symptoms. CONCLUSIONS: Although the results of standard TUR or open surgery imply higher success, the long-term results of ILC demonstrate effectiveness. Further follow-up studies on a larger number of patients are advisable. The low morbidity of ILC makes this procedure an interesting alternative option in the treatment of high risk patients.

[Sacral neuromodulation in patients with nonobstructive, chronic urinary retention: relevance of the carbachol test and influence of associated nerve lession]. / Sakrale Neuromodulation bei nichtobstruktiver, chronischer Harnretention: Die Wertigkeit des Carbacholtests und der Einfluss der assoziierten Nervenläsion.

OBJECTIVE: Aim of this study was to evaluate whether the carbachol test and the nerve lesions responsible for bladder dysfunction possess predictive value in patients with chronic urinary retention who undergo temporary sacral neuromodulation (PNE test). MATERIAL AND METHODS: In 1999 and 2000, PNE tests were performed in 24 patients with chronic urinary retention and acontractile detrusor previously assessed by urodynamics. In 18 patients, a carbachol test was performed during urodynamics. The diagnosis related to the acontractile detrusor was additionally assessed and compared to the successful outcome of the PNE test. RESULTS: The PNE test was successful in 8 of the 24 patients (33.3 %). The bladder was completely emptied during the PNE test in 3 of the 10 patients with negative carbachol test and in 3 of the 8 patients with positive carbachol test. The highest success rate (80 %) was observed in patients after hysterectomy, whereas after lumbosacral pulposal prolapse or with a CNS tumor, it was only 20 - 33.3 %. CONCLUSIONS: We conclude that sacral neuromodulation is an effective treatment option in patients with nonobstructive urinary retention. The carbachol test does not possess any definitive predictive value with respect to the success rate of sacral neuromodulation in patients with chronic urinary retention. The success rate more likely depends on the localisation of the nerve lesion. PNE tests should be performed in all patients with therapy resistent nonobstructive urinary retention, as no other predictive factors exist.

[Bladder wall tension with physiological bladder emptying in patients with detrusor hyperactivity and infravesical obstruction]. / Blasenwandspannung unter physiologischer Blasenentleerung und bei Patienten mit Detrusorhyperaktivität und subvesikaler Obstruktion.

PURPOSE: The range of maximum bladder smooth muscle tension in the published literature varies between 1.3 and 59 N/cm (2) depending on the experimental setup. Based on own animal trials, we attempted to determine bladder wall tension during detrusor contraction in physiological and obstructed voiding and during detrusor instabilities in our patient collective. MATERIALS AND METHODS: In 24 patients (mean age 56 +/- 8.4 years), bladder wall tension as detrusor force per cross sectional area of bladder tissue [in N/cm (2)] was calculated following urodynamic evaluation and ultrasound determination of bladder wall thickness. The patients were divided into 3 groups with 8 patients per group as follows: group I: patients with bladder outlet obstruction in accordance with the Abrams-Griffiths nomogramme; group II: patients with detrusor instabilities; group III: patients with normal bladder emptying. RESULTS: Maximum bladder wall tension in group I was 9.8 +/- 3.9 N/cm (2). During bladder instabilities (group II), maximum bladder wall tension was 11.7 +/- 2.6 N/cm (2). Maximum bladder wall tension was 2.8 +/- 0.5 N/cm (2) in group III, which was significantly lower (p < 0.05, Mann-Whitney U-Test) than that of groups I and II. CONCLUSIONS: We conclude that bladder wall tension is distinctly lower in patients with normal voiding than in those with obstructed micturition or detrusor instabilities. Furthermore, our results suggest that the detrusor is not fully activated during normal voiding and is thus capable of compensating for to a greater stress situation with more effective contractions.

[Tunica plication with horizontal incisions of the tunica albuginea in the treatment of congenital penile deviations]. / Tunikaplikatur mit horizontalen Inzisionen der Tunica albuginea in der Behandlung kongenitaler Penisdeviationen.

PURPOSE: The Schroeder-Essed plication procedure is a standard technique for the correction of penile curvature. In a retrospective analysis we compared functional results and quality of life of the original technique with inverted sutures as described by Schroeder-Essed and our slight modification consisting of horizontal incisions into the tunica albuginea. MATERIALS AND METHODS: A total of 26 patients with congenital penile deviation were treated, 11 by the original Schroeder-Essed plication with inverted sutures and 15 using the described modification. In the modified technique, horizontal and parallel incisions 4 mm - 6 mm apart and about 8 mm - 10 mm long were made through the tunica albuginea. The outer edges of the incisions were then approximated with permanent inverted sutures (Gore-Tex(R) 3-0). Mean age was 21.6 years in the first group and 23.2 years in the second group. The preoperative penile deviation angle was > 25 degrees in all patients without differention between the two groups. RESULTS: All patients in both groups reported improvement in their quality of life and full ability to engage in sexual intercourse. A total of 9 patients (88 %) in the first group and 14 patients (93 %) in the second group were satisfied with the cosmetic result, although 10 patients (91 %) in the first and 13 patients (87 %) in the second group complained of penile shortening. Recurrence of deviation was only observed in 2-males in the first group (18 %). CONCLUSIONS: Our results indicate that this simple modification of the Schroeder-Essed plication offers good functional and cosmetic results. Most patients were satisfied with the penile angle correction results.

[Urodynamic findings in patients with infantile cerebral palsy]. / Videourodynamische Erstbefunde bei infantiler Zerebralparese.

OBJECTIVE: Aim of study was to evaluate the urodynamic findings in patients with infantile cerebral palsy. MATERIAL AND METHODS: In 29 patients (aged 3-53), a videourodynamic investigation was performed after evaluation of urological anamnesis, clinical assessment and sonographic determination of residual urine. The patients were divided into group 1 (23 symptomatic patients aged 5 years and older with recurrent urinary tract infection, pollakiuria or urinary incontinence) and group 2 (6 asymptomatic patients). RESULTS: In group 1, 21/23 patients (91%) had reduced compliance (0.6 - 16.4 ml/cmH(2)O) and 16/23 patients (70%) increased leak point pressure (> 40 cmH(2)O). In all 23 patients, detrusor instability and detrusor sphincter dyssynergia (during voiding) was found. Fluoroscopy showed bladder trabeculation or diverticula in 14 patients (61%) and 2nd-3rd degree vesicoureterorenal reflux in 2 patients (9%). In group 2, 2/6 patients (33%) had reduced compliance (0.7 and 5.8 ml/cmH(2)O) and 4/6 (67%) increased leak point pressure (> 40 cmH(2)O). In 5/6 patients (83%), detrusor instability and detrusor sphincter dyssynergia was seen. Fluoroscopy showed bladder trabeculation in 3 patients (50%), whereas no reflux was observed. Only one of the 29 patients (3 %) showed no pathological videourodynamic or anamnestic findings. CONCLUSIONS: We conclude that videourodynamic assessment should be performed in all patients with infantile cerebral palsy. The decision should not be based on clinical symptoms such as pollakiuria, recurrent urinary tract infection or urinary incontinence.
