Current laparoscopic practice patterns in urology: results of a survey among urologists in Germany and Switzerland

Recent advances in urologic surgical techniques for pyeloplasty

Pyeloplasty is one of the most common urological reconstructive interventions. Since the presentation of the first open pyeloplasty by Anderson and Hynes in 1949, the management of ureteropelvic junction obstruction has dramatically developed. The most immense progress was made in the 1990s with the introduction of laparoscopy. A multitude of new minimal surgical techniques have been introduced since then. In the last few years, the innovations were based on refinement of already-existing techniques and technology. With this aim, single-port surgery, three-dimensional vision for laparoscopy, robotic technology, and alternative techniques for creating the anastomosis-like fibrin glue have been introduced. This unsystematic review is timely, and the scientific interest is to present and discuss some of the latest advances in surgical techniques and different approaches for the intra- and post-operative management in pyeloplasty. To the best of our knowledge, this is the only review looking at the recent advances in urological surgical techniques for pyeloplasty during the last few years with a focus on new technology and surgical techniques.

Simplifying laparoscopic nephrectomy: the inferior approach with en bloc stapling of the renal hilum

Introduction:

Laparoscopic nephrectomy (LN) is likely the most common laparoscopic procedure performed by general urologists without formal laparoscopic training. The traditional technique is cumbersome because it entails making an early approach to the hilum with the risk of bleeding and need for conversion. We perform a different technique that we believe is simpler to learn and to teach. It consists of a complete dissection of the inferior and posterior aspects of the kidney, followed by en bloc stapling of the renal hilum. The present report is a detailed description of our technique including outcomes and complications.

Materials and Methods:

Perioperative data of 129 consecutive patients who underwent LN between November 2003 and September 2007 were prospectively collected and retrospectively reviewed. Complications were reported using the Clavien classification system, and follow-up was performed according to our institution's protocol and included physical examination, blood count, blood chemistry, and renal function tests at every visit, in addition to abdominal computed tomography scan six months after surgery. Additional imaging was scheduled according to disease stage and grade.

Results:

Mean patient age, tumor size, and operative time were 63 ± 15.6 years, 6.3 ± 2.4 cm, and 128 ± 41.4 minutes, respectively. Median estimated blood loss was 0 mL (0.200). Conversion to open surgery occurred in 3.1% of patients, and 8% of the patients had a blood transfusion. Complications were recorded in 26% of the patients; 91% of them had Clavien grade scores of 1 or 2.

Conclusion:

We present a standardized technique for LN. Its main advantage is that postpones any manipulation of the hilum to a later step during the procedure when it is easy to identify and control. This decreases early bleeding and main vascular complications.

Current status of robot-assisted laparoscopic surgery in pediatric urology

Laparoscopic procedures for urological diseases in children have been proven to be safe and effective. However, the availability of laparoscopic procedures is still partly limited to experienced, high-volume centers because the procedures are technically demanding. The da Vinci robot system is being used for an increasing variety of reconstructive procedures because of the advantages of this approach, such as motion scaling, greater optical magnification, stereoscopic vision, increased instrument tip dexterity, and tremor filtration. Particularly in pediatric urologic surgery, where the operational field is limited owing to the small abdominal cavity of children, robotic surgical technology has its own strengths. Currently, robots are used to perform most surgeries in children that can be performed laparoscopically. In this review, we aimed to provide a comprehensive overview of the current role of robot-assisted laparoscopic surgery in Pediatric Urology by analyzing the published data in this field. A growing body of evidence supports the view that robotic technology is technically feasible and safe in pediatric urological surgery. Robotic technology provides additional benefits for performing reconstructive urologic surgery, such as in pyeloplasty, ureteral reimplantation, and enterocystoplasty procedures. The main limitations to robotic surgery are its high purchase and maintenance costs and that the cost-effectiveness of this technology remains to be validated.

Development of urologic laparoscopy in Germany, Austria, and Switzerland: a survey among urologists

PURPOSE

Laparoscopy introduction has dramatically changed urology. Novel techniques, such as laparoendoscopic single-site surgery (LESS) and natural orifice translumenal endoscopic surgery (NOTES), might also have substantial influence. This 2012 survey evaluated present laparoscopy use, its appraisal among urologic surgeons, laparoscopy training, and use of new techniques. Results were compared to the previous surveys, demonstrating the 10-year development of laparoscopy.

METHODS

A detailed questionnaire regarding demographic data, laparoscopy use, attitudes concerning laparoscopy, and novel techniques was send to 424 departments in Germany, Austria, and Switzerland. Procedures performed in 25 indications were quantitatively evaluated.

RESULTS

The response rate was 63 % (269). Eighty-six percent of the respondents reported performing laparoscopy, compared to 54 % in 2002. Only 16 % expected economic advantages with laparoscopy, whereas 67 % expected shorter hospitalization. Seventy percent of responders anticipated comparable functional and oncological results between laparoscopic procedures and open surgery. Slow learning curves (81 %) and insufficient training facilities (32 %) were reported to impair laparoscopic surgery. On average, laparoscopic and non-laparoscopic surgical teams consisted of 2.5 and 3.5 members, respectively. LESS procedures were performed at 15 % of institutions. Twenty-two percent of respondents considered NOTES techniques valuable for future urology. Few indications (laparoscopic prostatectomies or nephrectomies) were performed frequently in specialized centers, and the rapidly increasing procedure numbers observed between 2002 and 2007 had dropped to a mild accretion. The results demonstrate broad acceptance of laparoscopy in German urologic surgery, depict the need for structured training facilities, and indicate limited impact of novel techniques (LESS and NOTES).

CONCLUSIONS

The survey demonstrates the 10-year development of urologic laparoscopy and the broad acceptance of laparoscopic techniques.

[Comparison of the operation time and complications between conventional and robotic-assisted laparoscopic pyeloplasty]

OBJECTIVE

To compare the different times into which the convention and robotic-assisted laparoscopic pyeloplasty can be divided. To compare the rate of complications between both procedures.

MATERIAL AND METHODS

A retrospective study was performed of the patients diagnosed of pyeloureteral junction stenosis and treated with convention and robotic laparoscopic pyeloplasty with more than one year of follow-up. All of the interventions were recorded and visualized. The different times in which the pyeloplasty can be divided were measured. All of the peri- and post-operative complications that occurred by the patients were collected. The non-parametric tests of Kolmogorov-Smirnov and Mann-Whitney U-Test for independent samples were applied using a significance level of 0.05.

RESULTS

A total of 50 patients were validated. Thirty three were treated with convention laparoscopy and 17 with robotic laparoscopy. The suture time, total intervention time and time of hospital stay were lower with a statistically significant difference in the robotic-assisted pyeloplasty. The robotic pyeloplasty had a lower percentage of complications (76.5% vs 48.5%). The most frequent complications were urinary infections, in relationship to the double J. Two restenoses occurred in the conventional laparoscopy and one in the robotic-assisted. Success rate was 93.9% for the conventional laparoscopy and 94.1% for the robotic-assisted one.

CONCLUSIONS

Although the success rate is similar in both procedures, the robotic pyeloplasty is a very fast procedure and has lower rates of complications than the conventional laparoscopy.

Bilateral vs unilateral laparoscopic intrafascial nerve-sparing radical prostatectomy: evaluation of surgical and functional outcomes in 457 patients

Study Type - Therapy (case series).

LEVEL OF EVIDENCE

 4. What's known on the subject? and What does the study add? Bilateral nerve-sparing radical prostatectomy still represents an issue for urologists as the indications to perform it depend oft from the personal clinical experience. Moreover, until now data concerning bilateral and unilateral laparoscopic nerve-sparing radical prostatectomy have been limited. This study states that bilateral laparoscopic intrafascial nerve-sparing technique results in superior functional outcomes when compared with unilateral nsLRP and it suggests to prefer a bilateral nerve-sparing technique in younger patients with low-risk, organ-confined prostate cancer.

OBJECTIVE

To evaluate the surgical and functional outcomes in bilateral and unilateral nerve-sparing laparoscopic radical prostatectomy (nsLRP).

PATIENTS AND METHODS

Between January 2005 and May 2009, 457 nsLRP were performed at our clinic. In all, 250 patients underwent a bilateral nsLRP and 207 patients underwent an unilateral nsLRP. One surgeon performed all the operations. All patients presented at biopsy a localized prostate cancer. Demographic data and perioperative and postoperative measurements and outcomes were compared.

RESULTS

The operative times for bilateral nsLRP and unilateral nsLRP were 165 ± 45 min and 130 ± 25 min, respectively. The mean intra-operative blood loss was 450 ± 300 mL and 270 ± 160 mL in the bilateral and unilateral nsLRP groups with a transfusion rate of 3% and 1%, respectively (P = 0.013). Conversion to open surgery was never deemed necessary. Postoperatively, the mean Gleason Score after nsLRP and distribution of tumour stages was similar in the two groups, and the frequency of positive margins in both groups did not present any statistically significant difference. At 12 months, a complete continence was reported in 97% of patients who underwent a bilateral nsLRP and in 88% of patients of the unilateral nsLRP group. At that time, 69% in the bilateral nsLRP and 43% in the unilateral nsLRP groups reported the ability to engage in sexual intercourse.

CONCLUSION

The bilateral laparoscopic intrafascial nerve-sparing technique results in superior functional outcomes with regard to urinary continence and sexual potency, when compared with unilateral nsLRP, reporting similar oncological outcomes.

Laparoscopic radical prostatectomy: a review

INTRODUCTION

We offer an overview of the intra-, peri- and postoperative outcomes of laparoscopic radical prostatectomy (LRP) with the endpoint to evaluate potential advantages of this approach.

MATERIALS AND METHODS

We conducted an extensive Medline literature search (search terms "laparoscopic radical prostatectomy" and "radical prostatectomy") from 1990 until 2007. Only full-length English language articles identified during this search were considered for this analysis. A preference was given to the articles with large series with more than 100 patients. All pertinent articles concerning localized prostate cancer were reviewed.

CONCLUSION

Pure LRP has shown to be feasible and reproducible but it is difficult to learn. Potential advantages over open surgery have to be confirmed by longer-term follow-up and adequately designed clinical studies.

Laparoscopic vs open retropubic intrafascial nerve-sparing radical prostatectomy: surgical and functional outcomes in 300 patients

OBJECTIVE

To evaluate the surgical and functional outcomes in nerve-sparing laparoscopic radical prostatectomy (nsLRP) and retropubic nsRP (nsRRP).

PATIENTS AND METHODS

Between January 2005 and November 2007, 150 nsLRP and 150 nsRRP were performed at our clinic. Demographic data, variables before and after surgery, and outcomes, were compared.

RESULTS

The operative duration was 165 min for nsLRP and 120 min for nsRRP. Although the nsLRP group had a lower frequency of positive margins, the difference was not statistically significant. At 1 year after surgery, complete continence was reported in 97% of patients who had nsLRP and in 91% who had nsRRP (P= 0.03). At that time, 66% of patients in the nsLRP and 51% in the nsRRP group reported being able to engage in sexual intercourse (P < 0.05). There were no statistical differences in surgical trauma in both groups.

CONCLUSION

Our study showed that nsLRP performed by expert surgeons results in better functional outcomes for continence and potency than for nsRRP. There was no significant difference between the surgical techniques in surgical trauma.

Robot-assisted gynecological surgery in a community setting

The objective of this study is to review our experience using the da Vinci robotic system to perform various gynecological surgeries for benign indications. Between July 2005 and April 2008, 110 patients underwent robot-assisted gynecological surgeries in Rochester General Hospital, NY. The records of these patients were retrospectively reviewed by an independent data collector to analyze the safety, effectiveness, and outcome of the surgeries done using the robotic system. The parameters reviewed include indication for surgery, type of procedure, operative time, blood loss, hospital stay, and intraoperative and post operative complications. The procedures completed include 74 hysterectomies including hysterectomies with bilateral salpingoophorectomy, 15 hysterectomies with sacrocolpopexy and other concomitant procedures, 18 myomectomies, and 3 oophorectomies. All procedures were completed robotically without the need for conversion to an open approach. The mean operation time was 2.15 h. Average estimated blood loss was 160 cc. Complications encountered include one cystotomy which was identified immediately and repaired in addition to one vault dehiscence and two post operative infections. The mean hospital stay was 1 day, with more than half of the patients being discharged within 24 h after the surgery. Post operative pain level was in the range of 0-6 in a scale of 0-10 (0: no pain, 10: worst pain in their life) and relieved by non-steroidal anti-inflammatory drugs. Robot-assisted laparoscopic benign surgical procedures are feasible techniques in a community setting. Robot-assisted laparoscopy has a promising future in minimally invasive surgery as it proved beneficial for our patients who experienced low complication rate and overall fast recovery compared to other approaches.

Laparoscopy in German urology: changing acceptance among urologists

BACKGROUND

Laparoscopic techniques have dramatically influenced urologic surgery in the past 2 decades.

OBJECTIVES

A questionnaire was distributed in 2006 to analyse laparoscopic practice patterns in Germany. The results were compared with a survey performed in 2002.

DESIGN, SETTING, AND PARTICIPANTS

In 2006, 324 German urology departments received a detailed, anonymous, and self-administered questionnaire regarding demographic data, current use, and attitudes concerning laparoscopy. Quantitative evaluation of laparoscopic procedures was performed for 20 indications.

MEASUREMENTS

The response rate was 73% (238 of 324 institutions). Thirty-two responders were affiliated with universities; 95 responders were affiliated with urban hospitals; 101 responders were affiliated with general hospitals; and 9 responders were affiliated with private hospitals. Laparoscopy had been implemented as a standard operating procedure in 82% of the departments, an increase of 28% compared with the 2002 questionnaire. Forty-eight percent of participants expected a similar operating time to that of open surgery, an increase of 16% compared with the 2002 questionnaire. Concerns about the learning curve dropped from 92% in 2002 to 80% in 2006, and concerns about economic disadvantages dropped from 70% in 2002 to 45% in 2006. Criticism regarding lack of sufficient scientific data decreased from 76% in 2002 to 13% in 2006. Laparoscopic radical prostatectomies (>40 per year) were performed in 30 hospitals in 2006, an increase of 27% over 2002. Laparoscopic radical nephrectomy was performed 16-40 times per year in 33 of the responding institutions, an increase of 29% over 2002, and laparoscopic radical nephrectomy was performed >40 per year in 10 of the institutions, an increase of 9% over 2002. Laparoscopic pyeloplasty had a reported frequency of 16-40 procedures per year in 11 of the responding institutions, an increase of 10% over 2002, and laparoscopic pyeloplasty had a frequency between 5 and 15 procedures per year in 42 institutions, an increase of 37% over 2002. Only four hospitals performed cystectomy with ileum conduit and with orthotopic bladder substitute (5-15 cases per year).

RESULTS AND LIMITATIONS

The results demonstrate the rising acceptance of laparoscopy in urologic surgery (an increase of 28% more departments performing laparoscopy) and an increasing interest in these techniques (an increase of 12% in the response rate). Their value is still limited by the response rate of only 73%.

CONCLUSIONS

This survey demonstrates the increasing impact of laparoscopy on surgical patterns in urology and the increasing acceptance of laparoscopic techniques concerning operating time, learning curve, and scientific approval.

[Current operative strategies for rotator cuff tears in German hospitals]

The surgical treatment of rotator cuff lesions is still a controversial subject. We therefore decided to perform a study designed to yield an overview of the treatment modalities currently applied in Germany. A nationwide questionnaire survey was sent to 470 orthopaedic and trauma departments to ask about their surgical treatment of rotator cuff lesions: frequency of operative treatment, methods used in diagnosis and types of operative treatment; particular attention was paid to the application of minimally invasive techniques and to postoperative rehabilitation. The response rate was 55%. In all, 30,462 arthroscopic treatments were recorded for the year 2004, 9,094 of which were open or mini-open techniques and 2,528 were endoscopic reconstructions of the rotator cuff. Overall, we found that arthroscopic rotator cuff repair was performed in only 111 of the 257 departments from which responses were received and that the majority of surgeons preferred to use sutured and nonresorbable anchors. The postoperative treatment varies widely, from the full range of motion allowed within the first postoperative week to substantially more restrictive regimens. We see that the arthroscopic repair is still not the standard treatment for rotator cuff lesions in Germany. Further research is clearly still needed especially in the area of postoperative treatment.

Laparoskopische Beckenchirurgie

Laparoscopic radical prostatectomy has become an equivalent alternative to the open retropubic approach, offering the advantages of minimally invasive surgery. It is being applied increasingly in Germany and the rest of Europe. Whether the surgical robot da Vinci will be used for this procedure to the same extent as in the United States is unpredictable because of high investment and maintenance costs. Similarly, laparoscopic sacrocolpopexy has proven to be a viable option compared to open transabdominal or transvaginal surgery, showing a significant reduction in postoperative morbidity. The value of radical cystectomy is controversial despite proven feasability. On one hand, the technical difficulties of purely laparoscopic urinary diversion result in very long operating times, and in the case of the laparoscopically assisted creation of a neobladder, the advantage of this approach has to be questioned. On the other hand, a maximum rate of 30% of local recurrences and distant metastases indicates at least poor patient selection. In conclusion, this procedure should be limited to a few experienced centers.

Laparoscopic and Robotic Assisted Radical Prostatectomy – Critical Analysis of the Results

OBJECTIVE

To evaluate the role of laparoscopic radical prostatectomy (LRP) and robotic assisted radical prostatectomy (RLRP) based on personal experience and a review of the literature.

MATERIAL AND METHODS

Own experience at one European and one American LRP-center includes more than 2000 cases. We performed a MEDLINE search reviewing the literature on LRP and RLRP between 1992 and 2005 with special emphasis on historical aspects, technical considerations, comparison to open retropubic (RRP) and perineal radical prostatectomy (PRP), laparoscopic training, and the cost-efficiency of the techniques.

RESULTS

Based on sophisticated training programs a continuous dissemination of the technique took place. In the United States, this process was accelerated by the use of the daVinci-robot. There is a trend towards the extraperitoneal access. Mid-term outcomes of LRP achieved equivalence to open surgery with regards to complications, oncologic and functional results. Distinct advantages of LRP include less postoperative pain, lower rate of complications, shorter convalescence, and better cosmesis. In contrast to RLRP, LRP may reach cost-equivalence with open surgery (i.e. by reduction of OR-time, use of multi-usable instruments).

CONCLUSIONS

LRP reproduces the excellent results of open surgery providing the advantages of minimal access. Video-assisted teaching improves the transfer of anatomical knowledge and technical knowhow. In contrast the United States, the use of robots is likely to remain limited in Europe.

The laparoscopic nephrectomy learning curve: a single centre's development of a de novo practice

OBJECTIVE

There has been a dramatic increase in the interest and practice of laparoscopic urology, with nephrectomy having become the commonest laparoscopic urological procedure. Compared with open nephrectomy, it results in reduced morbidity and shorter convalescence times while maintaining oncological safety. However, while these results predominately stem from institutions with well developed laparoscopic programmes, little is known about the results in centres that have newly adopted this technique. The introduction of a laparoscopic urological service at the Royal Hallamshire Hospital provided an opportunity to study these factors.

METHODS

Since the appointment in October 2000 of a urological surgeon (N Oakley) to develop the laparoscopic service, there have been over 200 laparoscopic procedures including 121 nephrectomies performed at this centre. Full details were collected for each of these cases, and in addition, compared with retrospective data for 50 open nephrectomies performed during the same time period.

RESULTS

With increased operator experience the median operative duration, complication, transfusion, and conversion rates significantly improved. While a learning curve was evident, the overall operative complication (9%) and conversion rates (6%) were low, in addition to patient morbidity (16.5%) and mortality (0%) rates, showing that this learning curve had no deleterious effects upon patient care. The median hospital stay was four days, which reduced to three with experience and was significantly shorter than for open nephrectomy at this institution (p = 0.001).

CONCLUSIONS

The development of a successful laparoscopic programme can be achieved with a comparatively short learning curve and without detriment to the patient provided the necessary steps are observed.

Laparoscopic Radical Prostatectomy - the Experience of the German Laparoscopic Working Group

PURPOSE

To present the current status of laparoscopic radical prostatectomy (LRP) in Germany, Austria and Switzerland with respect to transferability, learning curve, and outcome.

MATERIAL AND METHODS

The data of 5824 patients who underwent LRP in 18 centers by 50 urologists from March 1999 to August 2004 were analyzed retrospectively. Three centers performed more than 500, and six more than 250 cases. A transperitoneal descending technique with was used in 2701, a transperitoneal ascending in 1234, an extraperitoneal descending in 1814, and an extraperitoneal ascending modification in 75 cases. Specimen showed pT2 in 3535, pT3a in 1555, pT3b in 623, and pT4 in 111 cases.

RESULTS

Mean operating time averaged 211 (131-292) minutes, with shorter duration of the extraperitoneal descending technique. Conversion to open surgery averaged 2.4 (0-14.1) %. Re-intervention rate amounted to 2.7 (0.3-7.7) %. Complication rate averaged 8.9 (1.8-10.8) % including bleeding (0.3-2.5%) and rectal lesion (1.5-2.5%). The rate of positive margins was 10.6 (3.2-18) % for pT2- and 32.7 (20-38.5) % for pT3a-tumors Continence after 12 months was 84.9 (72-94) %. Data about potency (7 centers) revealed 52.5 (35-67) % full erections following bilateral nerve preservation. 5 year-PSA recurrence rate (3 centers) was 8.6 (4-15.3) % for pT2-tumors and 17.5 (15-20.6) % for pT3a-stages.

CONCLUSIONS

The results confirm the efficacy of the training program with safe transfer of LRP (i.e. low complication rate), however including all known problems of a retrospective study.

Development of Laparoscopic Surgery and Training Facilities in Europe: Results of a Survey of the European Society of Uro-Technology (ESUT)

OBJECTIVE

The European Society of Uro-Technology (ESUT) conducted a survey in order to assess the application of laparoscopy and the facilitation of training programs within Europe.

METHODS

A total of 430 urologists and residents from European countries answered the ESUT survey during the XVIIIth Annual EAU Meeting in Madrid in 2003. The survey constituted of 11 questions of which nine with dual response (Y/N) options. Two questions, evaluating the importance of different training methods and different reasons not to be involved in laparoscopy, were assessed by means of a Likert type scale.

RESULTS

Laparoscopy was performed in 71% of urological departments. The majority (85%) of departments where no laparoscopy was performed, intended to establish it in the future. Two thirds of respondents believed laparoscopy would replace open surgery in the next 5 to 10 years. The access to training facilities was insufficient for 44%. Different methods of training were considered to be of equal importance. Among the reasons for not being involved in laparoscopic surgery a high variability was identified.

CONCLUSIONS

Laparoscopy is performed in the majority of urological departments in Europe. While there is a strong believe in the prominent role of laparoscopy in the mid-long future, access to training is still needed.

Current Trends in Urologic Laparoscopic Surgery

PURPOSE

We examined the status of laparoscopy in urology and the impact of residency and fellowship training on the performance of laparoscopy as primary surgeon. We also examined whether performing nonsurgical tasks requiring two-handed dexterity had any link to the adoption of laparoscopic techniques by urologists.

MATERIALS AND METHODS

A total of 8760 laparoscopy questionnaires containing 135 queries were mailed to urologists listed on the American Urological Association practicing urologists mailing list. The questions sought information on area of practice, time in practice, fellowship training, ambidexterity, laparoscopic experience, and experience with robotics. The response rate was 1.8% (155 of 8760).

RESULTS

There appeared to be no significant correlation between the performance of laparoscopic surgery and participation in activities requiring bimanual dexterity. However, a correlation of strong statistical significance did exist between laparoscopic residency training and performance of laparoscopy after residency (p=0.003. There also was a correlation between fellowship training in laparoscopy/endourology and doing laparoscopy as primary surgeon.

CONCLUSIONS

Participation in laparoscopic surgery during residency training is a major determining factor in performance of laparoscopy as a primary surgeon in practice. Younger surgeons trained in laparoscopy during residency are performing more laparoscopy post residency than those without laparoscopic training during residency. At present, there is a need to train more urologists in laparoscopy at the postgraduate level.

Does the extraperitoneal laparoscopic approach improve the outcome of radical prostatectomy?

Laparoscopic radical prostatectomy (LRPE) became the operative procedure of choice for patients with clinically localized prostate cancer in selected urologic centers around the world. Principal advantages are the minimal invasive nature of the procedure, a superior visualization of the operative field because of the magnification of the optical system, an exact and watertight anastomosis, the possibility of early catheter removal, and a potentially reduced amount of blood loss. Recent data show that oncologic outcome is not compromised by the minimal invasive nature of the procedure. However, a major drawback of LRPE is the transperitoneal route of access to the extraperitoneal organ of the prostate. Therefore, principal disadvantages of LRPE are potential intraperitoneal complications. Endoscopic extraperitoneal radical prostatectomy is a further advancement of minimal invasive surgery because it overcomes the limitations of LRPE by the strictly extraperitoneal route of access, combining the advantages of minimal invasive surgery with the advantages of an extraperitoneal procedure. This article reviews the literature on minimally invasive (laparoscopic and endoscopic-extraperitoneal) radical prostatectomy.

Present practice and development of minimally invasive techniques, imaging and training in European urology: results of a survey of the European Society of Uro-Technology (ESUT)

OBJECTIVES

The European Society of Urological Technology (ESUT) conducted a survey in order to assess and record the current trend between European urologists with regard to the application of new technologies in BPH, stone disease and imaging and to identify differences amongst urologists.

MATERIAL AND METHODS

A total of 854 certified urologists and residents coming from European countries answered the ESUT survey during the XVIth Annual EAU Meeting in Geneva in 2001. The respondents were classified according to the geographical origin (Eastern, Southern and Northern Europe), year of certification (before 1980, and every 5 years hereafter) and power of the department in beds (less than 25, 26-50, and more than 50) in order to identify any differences in the replies mainly due to economical reasons, national or hospital policy and personal attitudes.

RESULTS

According to the replies, in Eastern Europe more procedures related to BPH and stones are performed comparing to Northern and Southern Europe (165.8 versus 77.1 and 100.6/month/department, respectively). However, the Northern European urologists have access to every type of lithotriptor and most of the different minimally invasive treatments for BPH in a higher percentage, followed by the Southern and the Eastern European urologists. The most widespread intracorporeal lithotriptor is the pneumatic and the most common alternative minimally invasive BPH treatment is electrovaporization (80.7% and 45.6%, respectively). Holmium laser is the most frequent choice (40.1%) when the surveyed urologists were asked to choose which of the minimally invasive techniques would like to have access to. In total 79.4% (54.1% alone and 25.3% in collaboration with the radiologists) of the respondents perform the ultrasound studies while the remaining 20.6% declare that only the radiologists do the studies. Of the surveyed urologists, 92.8%, 89.6% and 94.9% are interested in hands-on courses, simulators and live surgery, respectively.

CONCLUSIONS

The data obtained from the 854 surveyed European urologists and residents can be used as a tool to highlight the disparity between European countries and to advance training of European urologists.
