Abstract
Purpose PCNL requires a lithotrite to efficiently break stones, and some devices include active suction to remove the fragments. We set out to determine the efficacy and safety of the Swiss LithoClast® Trilogy, in a prospective European multicentre evaluation and compared it to published stone clearance rates for Trilogy based on surface area (68.9 mm2/min) and using the 3D calculated stone volume (526.7 mm3/min). Methods Ten European centres participated in this prospective non-randomized study of Trilogy for PCNL. Objective measures of stone clearance rate, device malfunction, complications and stone-free rates were assessed. Each surgeon subjectively evaluated ergonomic and device effectiveness, on a 1–10 scale (10 = extremely ergonomic/effective) and compared to their usual lithotrite on a 1–10 scale (10 = extremely effective). Results One hundred and fifty seven PCNLs using Trilogy were included (53% male, 47% female; mean age 55 years, range 13–84 years). Mean stone clearance rate was 65.55 mm2/min or 945 mm3/min based on calculated 3D volume. Stone-free rate on fluoroscopy screening at the end of the procedure was 83%. Feedback for suction effectiveness was 9.0 with 9.1 for combination and 9.0 for overall effectiveness compared to lithotrite used previously. Ergonomic score was 8.1, the least satisfactory element. Complications included 13 (8.2%) Clavien–Dindo Grade II and 2 (1.3%) Grade III. Probe breakage was seen in 9 (5.7%), none required using a different lithotrite. Conclusions We have demonstrated that Trilogy is highly effective at stone removal. From a user perspective, the device was perceived by surgeons to be highly effective overall and compared to the most commonly used previous lithotrite, with an excellent safety profile.

Abstract
Introduction Ureteric strictures are well-documented complications related to surgery or radiation therapy. Minimally invasive treatment using endoscopic dilatation or laser incision is the standard practice. There are no existing guidelines on which techniques to use in the treatment of different stricture types and a paucity of data regarding long-term results. Purpose Our study aimed to retrospectively assess the long-term efficacy of minimally invasive treatment in benign and malignant ureteric strictures. Materials and methods Over a 5-year period, 2007–2012, we analyzed the data of 59 consecutive patients undergoing minimally invasive treatment for symptomatic ureteric strictures. We excluded 16 patients from final analysis due to failed access or loss to follow-up. All patients but one were treated with antegrade, retrograde balloon or catheter dilatations. Successful outcome was defined as an asymptomatic, completely catheter free patient, with stable renal function. Results 43 patients were eligible for retrospective final analysis. The largest proportion of strictures occurred following surgery combined with radiotherapy 8/43 (19%). Preoperative decompression was required in 30/43 (70%). We identified 32/43 (75%) balloon dilatations, 10/43 (23%) catheter dilatations and 1/43 (2%) laser incision. Overall success rate was 31/43 (72%). All 6 recurrences occurred within 36 months, 4 within the first 12 months. 3/6 patients were successfully re-dilated. Conclusion Minimally invasive treatment is a worthwhile alternative in strictures due to previous radiation and/or surgical treatment of malignancies. Most recurrences occurred within the first year. However, late recurrences arise; therefore, patients should be subject to long-term follow-up. Moreover, re-dilatation may be required.

Abstract
Purpose: Percutaneous nephrolithotripsy is an essential procedure for treating complex urinary calculi. To achieve optimal access to a large and complicated stone, an upper calyx puncture is often preferable. However, when performing a puncture above the 12th rib there is risk of an increased number of complications. In this retrospective study, we assessed the kind and frequency of complications after sub- and supracostal punctures of the collecting system of the kidney. Material and Methods: Between 1996 and 2001, 85 patients were treated with percutaneous nephrolithotripsy. In 63 patients a subcostal track, below the 12th rib was established. Puncture was performed under ultrasonic or fluoroscopic guidance in 61 patients and CT-guided in 2 patients. In 17 patients a supracostal puncture, above the 12th rib, was performed under CT guidance and in 5 patients with US or fluoroscopic guidance. Result: The main difference regarding preoperative complications was the number of patients complaining of respiratory correlated pain, 7 (32%) in the supracostal puncture group compared with 3 (5%) in the subcostal puncture group. No significant difference regarding peroperative complications was found. Postoperatively, there were 2 major bleedings, one in each group, which had to be treated with arterial embolization. In the supracostal puncture group there were 2 patients with pleural effusion and 2 patients with pneumothorax. Conclusion: The complication rate was slightly higher after supracostal puncture as compared with a subcostal approach, especially regarding respiratory correlated pain. When performing a supracostal puncture there is an increased risk that the track passes through the pleural space, which might explain the difference in the panorama of complications.

Abstract
PURPOSE To investigate prospectively the benefits of three-dimensional stereolithographic biomodeling produced from CT data as an aid to achieving optimal access for percutaneous nephrolithotripsy (PCNL). PATIENTS AND METHODS Eight patients with complex urinary calculi were selected. Multislice CT scans of the kidney in native and excretory phases were acquired with the patient in the prone position to simulate the position during surgery. Contiguous reconstructed slices were produced from the data volume. The data of interest were processed to transform them into a format acceptable for production of a biomodel. Exact plastic replicas of the pelvicaliceal system and the calculi were created and used for morphologic assessment, preoperative planning, patient education, and surgical navigation. RESULTS The survey results were based on subjective opinions rather than objective data. The biomodels enhanced the ability to visualize a patient's unique anatomy before surgery. This aided the planning and rehearsal of endourologic procedures. CONCLUSION Although this study is only a preliminary investigation, we postulate that biomodeling has the advantage of allowing imaging data to be displayed in a physical form. In difficult cases, this technique may improve treatment, operative planning, and communication with colleagues and patients. The limitations of the technology include the manufacturing time and cost, but more accurate puncture-site selection may reduce costs by saving operating time.

Abstract
Although some authors have proposed that the favorable impact of transurethral microwave thermotherapy (TUMT) for benign prostatic hyperplasia has only a placebo effect, this idea is inconsistent with the findings of a number of sham-controlled clinical trials. Histologic and immunohistochemical studies have shown that the nerve fibers in the periurethral tissue are damaged or ablated by TUMT, and it appears that the heat affects the innervation of the smooth muscle cells. Among the nerves damaged are the sensory neurons of the posterior urethra, and this change might reduce the excitatory signals from the urethrodetrusor facilitating reflexes. Necrosis and apoptosis within a limited area also have been described. Thus, there is likely more than one basis for the therapeutic effect of TUMT.

Abstract
OBJECTIVES To determine whether transurethral microwave thermotherapy (TUMT) affects the sensory threshold in the posterior urethra and whether such an effect influences urinary storage symptoms. PATIENTS AND METHODS The sensory threshold was measured before and at 3 and 12 weeks after TUMT in 13 men with minor obstructive symptoms caused by benign prostatic hyperplasia. Sensations were evoked by electrical stimulation at different frequencies, using a bipolar ring-electrode mounted on a urethral catheter. Changes in sensory thresholds were evaluated in the patients both as a group and individually. The patients were interviewed about their symptoms at each measurement. RESULTS After TUMT, 12 patients were satisfied and reported decreased irritative symptoms, primarily less frequent nocturnal micturition; two patients were cured of urgency incontinence. In 11 of the satisfied patients, and the unsuccessful patient, decreased urge accompanied increased sensory thresholds. Thresholds elevated by >/= 30% were correlated with decreased irritative symptoms. CONCLUSIONS TUMT decreases sensitivity in the posterior urethra, which may alleviate storage symptoms.

Abstract
OBJECTIVE To determine whether heat, used in transurethral microwave thermotherapy (TUMT) for benign prostatic hyperplasia and which causes necrotic lesions within the adenoma, induces apoptosis in benign human prostatic stromal cells. Materials and methods Prostatic stromal cells were cultured from benign human prostatic tissue. The origin of the cells was identified by immunohistochemical staining and transmission electron microscopy. Cell cultures were exposed to moderate hyperthermia (47 degrees C) for 1 h and any apoptosis detected by light microscopy, transmission electron microscopy and the measurement of induced caspase-3-like activity. RESULTS The cultures contained a mixed population of smooth muscle cells and myofibroblasts. Twenty-four hours after heat exposure, 76% of the cells were apoptotic and the caspase activity had increased, whereas only 14% of the cells were necrotic. CONCLUSION Moderate hyperthermia induces apoptosis in cultured human prostatic stromal cells.

Abstract
A questionnaire sent by the Swedish Association of Urology to all active Swedish urologists (n = 249) was returned by 89%. Questions concerned actual urological work, emergency duties, education, development facilities and research access, but also job satisfaction, psychological fatigue and emotional stress, as well as each urologist's plans for the future. Answers indicate that Swedish urologists carry a heavy work load and experience considerable demands from patients, relatives and colleagues. Physical and psychological exhaustion are common, and many hope to find work outside hospitals or abroad. The tightening of health-care purses presumably augments the work load, but local factors are also involved. For the future, more and improved educational programs are planned, together with greater participation on the part of junior doctors in organizational and structural processes. Compared to other physicians, urologists show greater reserves of psychic energy, but also signs of increasing intellectual exhaustion.

Abstract
PURPOSE To determine whether transurethral microwave thermotherapy (TUMT) affects innervation of the urethra and periurethral prostate. MATERIAL AND METHODS Ten patients with troublesome benign prostatic hyperplasia (BPH) were treated with TUMT 1 week prior to transurethral resection of the prostate (TURP). At surgery, a biopsy was taken for histological examination and for immunohistochemical staining of the non-specific neuromarker protein gene product (PGP) 9.5. Control material consisted of identical biopsies from 10 patients undergoing TURP because of BPH, but not subjected to TUMT prior to surgery. RESULTS Histological examination revealed well-preserved, non-necrotic tissues in all biopsies. Nerve fibres were completely or almost absent in the smooth muscle layer in all but one of the TUMT cases, whereas all non-TUMT patients exhibited large numbers of nerve fibres in the smooth muscle layer. CONCLUSIONS TUMT does affect innervation of the urethra and periurethral prostatic tissue.

Abstract
OBJECTIVE To study the differences in subjective and objective results after 30 or 60 min of transurethral thermotherapy (TUMT) or sham treatment in men with benign prostatic hyperplasia (BPH). PATIENTS AND METHODS Forty-four patients with lower urinary tract symptoms caused by BPH were randomized to undergo 30 or 60 min of TUMT or sham treatment (14, 16 and 14 patients, respectively). The patients were evaluated using symptom scores, timed micturition, free flow rates and urodynamics before and after treatment. They were followed for 1 year, at the end of which they rated the treatment results on a self-administered visual analogue scale. RESULTS Forty-two patients completed the study. The treatment failed in some patients in all groups, but the improvement in maximum and median flow rates, timed micturition and micturition frequency (day and night) was greater after TUMT than in the sham-treated group. Symptom scores also improved more after TUMT, although not significantly. There was a good correlation between the decrease in urinary frequency, especially nocturnal, and the patients' perception of a successful treatment, whereas the increase in maximum urinary flow rate was apparently of little importance. CONCLUSIONS TUMT had a better effect than the placebo treatment, having a greater impact on irritative than on obstructive symptoms. More patients were satisfied after the 30-min than after the 60-min treatment.

Abstract
OBJECTIVE To study the extension and type of tissue damage in prostatic adenomas after transurethral microwave thermotherapy (TUMT). PATIENTS AND METHODS Seven patients with benign prostatic hyperplasia and scheduled for open adenectomy underwent TUMT before surgery. TUMT was performed 2 h before operation in one patient, 24 h before in five and one week before in the remaining patient. The excised adenomas were examined by routine light microscopy. In addition, the terminal deoxynucleotidyl nick-end labelling (TUNEL) technique was used to search for DNA-strand breaks in areas with morphological alterations suggestive of apoptosis. Due to technical problems, TUMT was inadequate for one patient, i.e. the effect given was extremely low. RESULTS In six cases, histopathological changes were found in limited areas extending from the urethra for 20-25 mm into the prostatic tissue. The predominant histopathological findings were areas of necrosis surrounded by cells with apoptotic features. The latter proved to be TUNEL-positive, i.e. they contained nuclei with DNA fragmentation of the apoptotic type. In the case with inadequate TUMT, there was no heat-induced tissue damage. CONCLUSION The area of tissue damage seen after TUMT was relatively small compared with the volume of the prostates. The main histopathological finding was massive necrosis, but cells undergoing apoptosis were also identified. Obviously, temperatures lower than those leading to necrosis induced apoptosis, which is a discrete type of cell death not associated with oedema or inflammatory reaction.

Abstract
Results of transurethral microwave thermotherapy for benign prostatic hyperplasia were good after 1 year in 68% of 66 cases. Despite good correlation between subjective assessment of results and improvement in urodynamic parameters, no predictive factors for probably successful outcome could be identified. Diminution in frequency of micturition (diurnal from 8.8 to 6.8 times, nocturnal from 3.0 to 1.6 times), increased flow rates (Q max from 8.8 to 14.2 ml/s) and reduction of detrusor pressures during voiding (Pdet max from 86.9 to 75.0 cm H2O) were significant, but the change in residual volume (from 52 to 37 ml) was of lesser degree (all mean values). Transurethral microwave thermotherapy can be tried for relief of moderate obstruction when transurethral prostatic resection involves risk, or the patient himself requests noninvasive treatment.

Abstract
Thirty-seven patients with clinically localized prostate cancer of all grades were treated by suprapubic digitally guided implantation of 125I seeds. The median age at the time of diagnosis was 68 years. The mean follow-up period was 62 +/- 19 months. At last follow-up 18 patients were clinically free of disease; 11 deaths occurred: 9 from prostate cancer and 2 from another disease. Complications occurred in 24 patients most commonly urgency and proctitis, attributable to the treatment. Four patients had severe late rectal complications, and 2 patients died of sepsis secondary to rectal fistulae. Digitally directed retropubic implantation of 125I appears inferior to other treatments of clinically confined prostate cancer both regarding outcome as well as complication rate.
