RESUMEN

Purpose: To assess the influence of holmium laser cystolitholapaxy (HLC) concomitantly with holmium laser prostate enucleation (HoLEP) on patients with benign prostatic hyperplasia (BPH) presenting bladder calculi. Materials and Methods: We present a retrospective analysis of patients with BPH (with or without concomitant HLC) at three Spanish centers. Intraoperative variables (e.g., time and resected tissue), changes in functional parameters of the prostate, and frequency of complications (intraoperative, early postoperative, and at 12 months) in patients with and without HLC were compared. Results: The analysis included 963 patients aged 48 to 91 years, of which 54 (5.6%) underwent HLC to treat vesical lithiasis. Mean (range) prostate size (measured by transrectal ultrasound) was 79 (43-173) g and 91 (35-247) g for patients with and without concomitant HLC, respectively (p = 0.080). All bladder calculi were effectively removed. No significant differences were found regarding enucleation and morcellation times, but total operation time was significantly higher in patients with HLC: mean (standard deviation [SD]) of 78 (27) minutes vs 95 (41) minutes (p < 0.001). Three patients underwent conversion to open surgery because of bladder perforation, all of them from the group without HLC. Rates of intraoperative, early, and 12-month complications were similar in both groups. No significant differences in International Prostate Symptom Scale, maximum flow rate (Qmax), and mean flow were observed between groups 12 months after surgery. Conclusions: Simultaneous HoLEP and HLC increases the total operation time, but does not influence the risk of clinically relevant perioperative and postoperative complications.

RESUMEN

INTRODUCTION: The objective of this study was to determine whether listening to music during a session of extracorporeal shockwave lithotripsy (ESWL) improves patients' pain. MATERIAL AND METHOD: A simple, blind randomisation was undertaken of patients with kidney and ureter stones attending an ESWL session of 7,000 waves for the first time, between September and December 2014. One group was given music and the other was not. The age, gender, location of stones (kidney/ureter) were recorded and 2questionnaires: pre ESWL (questionnaire A) and postESWL (questionnaire B). Each questionnaire contained a question about anxiety and another question on pain on the Likert scale (0-10). Questionnaire B also had a question on satisfaction and comfort (Likert 0-10). Other variables included heart rate, respiratory rate, systolic and diastolic blood pressure on wave 2,000, 5,000 and 7,000, reason for halting the procedure, total pethidine (mg), secondary analgesia, energy (J) and frequency (Hz). Bivariate analysis using the Student's t-test, X2/Fisher test and a multiple linear regression model. RESULTS: The sample comprised 95 patients, with a mean age of 52 (±13) years, 35 (36.84%) females, 60 (63.2%) males. A total of 25 (26.3%) ureter stones and 70 (73.7%) kidney stones. A number of 42 (44.2%) patients were given music. There were no differences between the demographic variables or questionnaire A scores. Satisfaction and pain were better on questionnaire B with music. CONCLUSION: Music can reduce pain and improve patient satisfaction in ESWL treatment. More studies are required to confirm this effect.

RESUMEN

OBJECTIVES: To compare the efficacy and reliability of Ho:YAG laser lithotripsy (HLL) and pneumatic lithotripsy (PL) in the treatment of bladder stones in patients with benign prostatic hyperplasia and stones ≥ 20 mm who were transurethrally treated in the same surgical session. METHODS: We studied the data of patients with benign prostatic hyperplasia and ≥20 mm bladder stones who were treated with transurethral resection of the prostate and cystolithotripsy in the same session, obtained between January 2010 and February 2014 from three urology clinics. All patients underwent bipolar plasmakinetic (PK) transurethral resection of the prostate. For treatment of the bladder stone, either HLL or PL was applied. A total of 62 patients were divided into two groups: PK-PL (Group 1, n = 29) and PK-HLL (Group 2, n = 33). The data of both groups were analyzed for stone dimensions, stone fragmentation time, total operating time, hospitalization duration, prostate dimensions, success rates, and complications. RESULTS: Group 1 included 29 patients with a mean age of 70 ± 7.6 (range, 57-85) years, whereas Group 2 included 33 patients with a mean age of 67.5 ± 10.5 (range, 45-84) years. In Group 1, five patients had mucosa injury, one patient had residual stone, and one patient had bladder perforation. In Group 2, three patients had mucosa injury, three patients had postoperative fever, and one patient had residual stone. Total operation time and stone fragmentation time were significantly lower in Group 2 (p < 0.05). The remaining analyzed data were similar (p > 0.05). CONCLUSION: PK-HLL using a single shaft without the need for repeated access has the advantages of shorter fragmentation and operation time.

RESUMEN

INTRODUCTION: This study aimed to determine the safety and efficacy of a modified technique for performing transurethral resection of the prostate (TURP) combined with percutaneous cystolithotripsy (PCCL). METHODS: Clinical data from 24 patients with benign prostate hyperplasia (BPH) and aggregate stone sizes ≥3 cm were assessed retrospectively between June 2011 and January 2014. All stones fragmented via pneumatic lithotripter were removed. An 18-F Foley catheter was inserted into the Amplatz sheath, which was then removed from the bladder. The Foley catheter balloon was inflated with 15 ml of saline, and suprapubic traction was applied to prevent extravasation. Next, TURP was performed while a suprapubic Foley catheter provided continuous drainage. RESULTS: The mean stone size was 46.25 ± 9.51 mm. The surgical duration for stone removal was 31.25 ± 8.46 min. All patients were stone-free at the first month follow-up. None of the patients experienced extravasation or urethral stricture. CONCLUSIONS: PCCL is a short-duration, minimally invasive surgery that avoids urethral stricture. In the presented technique, as the drainage catheter is fixed to the dome of bladder, it is not visualized in the surgical field and remains outside of the resection area, which facilitates prostate resection. It seems to be a safe and efficient technique.

RESUMEN

A 78 year old man with tetraparesis, reduced forced vital capacity, and neurogenic bladder dysfunction due to Guillain-Barré syndrome was admitted for elective transurethral prostate resection and percutaneous lithotripsy of a bladder stone. On the sixth postoperative day, he was readmitted for emergency evacuation of a clot in the bladder. Both operations were performed with spinal anesthesia (hyperbaric bupivacaine + fentanyl) without neurologic sequelae.

RESUMEN

OBJECTIVES: To evaluate the feasibility and effectiveness of transurethral holmium:yttrium-aluminum-garnet (YAG) laser cystolithotripsy under local anesthesia in selected patients. METHODS: Thirteen consecutive male patients with large bladder calculi (3 cm or greater) caused by benign prostatic hyperplasia underwent transurethral cystolithotripsy using holmium:YAG laser under local anesthesia. The operation was performed with all the patients in the lithotomy position (except 3 with pelvic prosthesis). All patients underwent transurethral holmium laser cystolithotripsy (HLC) with a flexible cystoscope under local anesthesia by 1 surgeon. A urethral Foley catheter was placed postoperatively. RESULTS: Thirteen patients with a mean age of 58.2 years were managed with HLC. All patients were rendered stone-free, regardless of stone size. No patient underwent transurethral resection of the prostate at the completion of the procedure. The mean stone size was 3.6 cm (range 3-5) and the mean operative time was 51 minutes (range 45-65). The whole procedure was well tolerated and no significant differences were found in the mean pain score between the HLC group and a group of male patients who underwent flexible cystoscopy under local anesthesia (2.15 vs 1.86, respectively; P = .467). No major intraoperative complication occurred. The mean hospitalization was 2.3 days. After a mean follow-up of 16.6 months, no recurrent stone, urinary retention, or urethral stricture developed. CONCLUSIONS: Transurethral holmium:YAG laser lithotripsy under local anesthesia appears to be a safe and effective technique for the large bladder calculi. Thus, it may be used as an alternative treatment option in selected patients.

RESUMEN

BACKGROUND AND PURPOSE: We compare two modalities of treatment; transurethral cystolithotripsy (TUCL) and percutaneous cystolithotripsy (PCCL), for large vesical calculi in patients who underwent simultaneous transurethral resection of prostate (TURP), and present refinements of the technique of PCCL. PATIENTS AND METHODS: Between July 1999 and June 2003, 54 patients were subjected to either TUCL (n = 19) or PCCL (n = 35) along with simultaneous TURP. Inclusion criteria were prostate volume > 50 ml, aggregate stone size > 3 cm with each individual stone > 1 cm, In the TUCL group, calculi were treated with 26F nephroscope, pneumatic lithotripsy and fragment extraction. This was followed by TURP with 26F continuous-flow resectoscope. In the PCCL group, calculi were removed through a suprapubic 30F Amplatz sheath followed by standard TURP with the suprapubic sheath in situ to provide continuous drainage. A 20F two-way Foley catheter was inserted suprapubically and urethrally in cases of PCCL and a 22-24F three-way catheter urethrally after TUCL. RESULTS: The two groups were comparable in age. The mean prostate size as well as aggregate stone size was significantly larger in PCCL group. The operating time for stone removal was significantly less in the PCCL group while time required for TURP was statistically similar in two groups. In the TUCL arm three patients had residual stones requiring repeat TUCL, and one developed a urethral stricture. CONCLUSIONS: Combined TURP and PCCL is safe, more effective and a much faster alternative to combined TURP and TUCL in patients with large bladder calculi and large prostates.

RESUMEN

OBJECTIVE: To report experience with holmium laser enucleation of the prostate (HoLEP) simultaneously with transurethral holmium laser cystolithotripsy (HLC) for managing bladder outlet obstruction (BOO) and associated vesical calculi; we also review previously reported cases of managing vesical calculi and associated BOO. PATIENTS AND METHODS: The high-powered holmium laser is a very efficient multifunctional endourological instrument that effectively fragments calculi of all compositions and is capable of haemostatic cutting of tissue, resulting in minimal bleeding after prostatic resection. A prospective study was conducted from April 2003 that included 32 men who underwent simultaneous HoLEP with transurethral HLC at our institution. Demographic, laboratory, peri-operative and follow-up data were analysed. Complications during and after surgery were identified to assess the morbidity of procedure. RESULTS: The mean (range) size of bladder calculi was 34.6 (12-70) mm and the preoperative weight of the prostate was 51.9 (11-172) g. Combined HoLEP with transurethral HLC was technically feasible in all patients, and all were stone-free after surgery. The mean operative duration was 97.7 (40-230) min, the weight of prostate tissue removed 34.6 (5-88) g, and the duration of catheterization and hospital stay 29.3 h and 34.8 h, respectively. Complications during and after surgery occurred in 12.5% and 15.6% of patients, respectively; all complication were minor and none caused any residual disability to the patient. No patient required a blood transfusion or developed clot retention. CONCLUSIONS: Managing bladder stones and BOO with simultaneous transurethral HLC and HoLEP should be considered the treatment of choice for such cases. Stones of any size and composition, and prostates of practically any size can be treated endoscopically using the holmium laser, with acceptable morbidity once the technique is mastered. The review of previous reports suggested a need for a prospective study comparing endoscopic management of BOO and associated bladder stones, with medical management of BOO and extracorporeal shock wave lithotripsy/endoscopic lithotripsy for bladder stone.

RESUMEN

OBJECTIVES: To assessed the feasibility and effectiveness of percutaneous cystolithotripsy under local anesthesia in selected patients. METHODS: Thirty-one patients with bladder stones of different etiologies underwent percutaneous cystolithotripsy under local anesthesia. Suprapubic access was obtained with ultrasound guidance, and fragmentation of the stone was performed using the Swiss lithoclast. Suprapubic and transurethral catheters were placed postoperatively. RESULTS: No major intraoperative complications occurred. The whole procedure was well tolerated, and no significant differences were found in the mean pain score between the percutaneous suprapubic cystolithotripsy group and a group of male patients who underwent rigid cystoscopy under local anesthesia (P = 0.35). Complete stone clearance was achieved in all but 1 patient (96.78%). Bladder irrigation because of gross hematuria was needed in 5 patients, but no blood transfusion was required. Fever developed in 1 patient and was treated with intravenous antibiotics. The average hospitalization was 2.3 days (range 2 to 5). After a mean follow-up of 10 months, no recurrent stone developed. CONCLUSIONS: Percutaneous suprapubic cystolithotripsy under local anesthesia is a safe and effective technique to remove bladder calculi. Thus, it may be used as an alternative treatment option in selected patients.

RESUMEN

OBJECTIVES: To present a combined endourologic approach to treat bladder calculi consisting of simultaneous percutaneous suprapubic and transurethral cystolithotripsy. METHODS: We report on a series of 12 consecutive patients with bladder stone burdens of 40 mm or greater. Percutaneous 30F access was obtained under cystoscopic control. Fragmentation and stone removal were performed simultaneously by two urologists using a Swiss lithoclast, holmium laser, and/or ultrasound lithotriptor through both percutaneous and transurethral routes. Suprapubic and transurethral catheters were placed postoperatively. RESULTS: Twelve patients with a median age of 66 years (range 33 to 80) were treated by simultaneous percutaneous suprapubic and transurethral cystolithotripsy. Six underwent transurethral resection of the prostate at the completion of stone clearance. The median stone size was 60 mm (range 40 to 80), and the median lithotripsy time was 56 minutes (range 45 to 70). The median postoperative hospitalization was 2.7 days (range 2 to 5), and complete stone clearance was achieved in all cases. One patient, who underwent concomitant transurethral resection of the prostate, developed urinary retention 1 week postoperatively and was successfully treated by temporary transurethral catheterization. One patient with a positive urine culture preoperatively developed fever on the first postoperative day and was treated with intravenous antibiotics according to the antibiogram results for 5 days. No other complications had occurred after a median follow-up of 10 months (range 3 to 15). CONCLUSIONS: Simultaneous percutaneous suprapubic and transurethral cystolithotripsy appears to be a safe approach for the management of large bladder calculi and may shorten the total fragmentation time. It can be combined with transurethral resection of the prostate without prolonging hospitalization. The simultaneous use of two modalities of stone fragmentation represents an effective and minimally invasive way of treating large bladder calculi.

RESUMEN

Objective of this study is to determine the difference in early peri-operative morbidity of transurethral resection of prostate (TURP) and if it is combined with inguinal hernia repair and mechanical and/or pneumatic fragmentation of bladder calculus. All patients undergoing TURP, cystolitholapaxy (CLL), inguinal hernia repair (IHR) or any combination between January 1997 and December 1999 were identified using ICD 9CM coding and indexing system. Overall 1273 patients were identified, charts were reviewed for demographics, pre-operative parameter, intra-operative data and early peri-operative morbidity. In the three year period, 19 patients had TURP and inguinal herniorrhapy (IHR), 17 patients had TURP and cystolitholapaxy (CLL), 2 patients had TURP+IHR+CLL performed simultaneously; in the same period 346, 815, 74 patients had TURP, IHR, and CLL alone respectively. All the groups were matched for age, presentation and Co-morbidities. There was significant difference in the operating time between the different groups. Complications were not significantly different in the TURP, IHR, CLL, TURP+IHR, and TURP+CLL. In conclusion, mean operative time for TURP+IHR is increased by a fraction of 168.3 for TURP+CLL by 109.8 and TURP+IHR+CLL is 202.1 over TURP alone, with no significant difference in morbidity between TURP and TURP+IHR and TURP+CLL.

RESUMEN

PURPOSE: We report our experience with the combination of ballistic lithotripsy (BL) and transurethral resection of the prostate (TURP) in 120 patients with benign prostatic hyperplasia (BPH) and bladder stone(s). PATIENTS AND METHODS: The mean stone size, appreciated by measuring the greatest diameter, was 18.5 mm (range 10-80 mm). The mean prostate volume was 35.4 cc (26-62 cc). All procedures were monitored under direct endoscopic control with a videocamera. RESULTS: Lithotripsy and evacuation of fragments was performed in an average time of 27.5 minutes (10-80 minutes). The only intraoperative complication was mild hematuria in 38 patients (32%), which did not affect vision for TURP. The mean resection time was 42 minutes (range 15-65 minutes). Four patients experienced mild postoperative bleeding, and one patient had clot retention. The mean hospital stay was 1.2 days (range 1-4 days). CONCLUSIONS: Combined BL and TURP is effective, safe, and economical.

RESUMEN

Bladder stones in children have decreased now compared with the previous decade. If we promote good nutrition for children, bladder stones will decrease and might be eradicated in the future. A seminar of doctors and health personnel from 19 hospitals in the north-eastern provinces of Thailand was conducted to survey bladder stones in children by weighting and interviewing bladder stone symptoms then giving supplementary diet milk and vitamins and teaching health education about nutrition and urinary stones through referring children with bladder stones to hospitals in north-eastern Thailand for surgery. The findings of the stone patients from October 1995 to June 1996 from hospitals in northern Thailand were: Total number of patients was 6671 of which 287 patients (4.3%) were 10 years old or younger. Of these children there were 135 renal stone operations (2.0%), 29 ureteric stone operations (0.4%), 106 bladder stone operations (1.6%) and 17 urethral stone operations (0.3%). There were 6384 patients aged more than 10 years. (95.7%) The total number of operations was 5373.

RESUMEN

Seventeen cases of urinary calculi analyzed by infrared spectrophotometry were found to be composed entirely or nearly entirely of bihydrated calcium hydrophosphate. The observations are summarized here. This type of stone occurs with a frequency of about 1% (0.85% in our experience) of all urinary calculi, predominantly in men (14 of our 17 cases). Diagnosis is based on the physical and chemical analysis of the stone and on infrared spectrophotometry. Most of these stones are pure or nearly pure compounds. The macroscopic aspect of the stones or fragments of stones can guide diagnosis. These stones are cream coloured stones with a smooth regular outer surface. Broken fragments show the same cream colour, sometimes with strips radiating from the centre of the fracture surface. Radiologically, these stones are homogeneously radio-opaque, often oval-shaped with a regular outline. Blood tests can demonstrate suspected or proven hyperparathyroidism (4 out of 10 cases in our 17 observations) with hypercalcemia, hypophosphatemia and hypercalciuria. Complementary examinations may be needed to search for a parathyroid adenoma. With or without hyperparathyroidism, 24-h urinalysis usually shows hypercalciuria up to ro over 500 to 600 mg/24 h. Crystallization usually occurs in the upper urinary tract, in the bladder or in indwelling catheters. These stones are extremely hard and are difficult to break in vitro. To be successful, lithotripsy requires prolonged treatment: up to 3000 to 6000 shockwaves at 22-23 kv with the Dornier apparatus. Despite the notion of hypercalciuria, the pathogenesis of bihydrated calcium hydrophosphate calculi remains to be elucidated.

RESUMEN

The fresh juice of Musa stem (Puttubale) was tested for its antilithiatic activity. Zinc discs were implanted in the urinary bladder of albino rats to induce urolithiasis. The stones formed were mainly of magnesium ammonium phosphate with traces of calcium oxalate. Musa stem juice (3 mL/rat/day orally) was found to be effective in reducing the formation and also in dissolving the pre-formed stones.
