Percutaneous suprapubic cystolithotripsy for treatment of large bladder calculi

BACKGROUND AND PURPOSE: The treatment options available for managing bladder calculi include transurethral cystolithotripsy, open cystolithotomy, and shockwave lithotripsy. For larger calculi, transurethral treatment can be time consuming, and the manipulation has the potential to cause urethral injury. Percutaneous suprapubic cystolithotripsy represents another treatment option for bladder calculi which is effective and minimally invasive. PATIENTS AND METHODS: Fifteen patients had bladder calculi treated with percutaneous cystolithotripsy over a 3-year period. The mean stone size was 39 mm (range 10-64 mm). Stones were single in seven patients and multiple in eight patients. The indications for cystolithotripsy were stone size >3 cm, multiple stones >1 cm, and inability to perform transurethral cystolithotripsy because of patient anatomy. Percutaneous suprapubic cystolithotripsy was done through either a 30F or a 36F cystotomy tract. Fragmentation and removal was performed with a 26F rigid nephroscope and the pneumatic Swiss Lithoclast. Suprapubic and urethral catheters were placed postoperatively in all patients. RESULTS: Each patient was cleared of the stone burden with a single procedure, and there were no major complications. The mean duration of suprapubic catheterization was 2.6 (range 1-5) days. CONCLUSION: Percutaneous suprapubic cystolithotripsy is an effective and safe technique for treating large bladder calculi. It is minimally invasive, avoids urethral injury, and, in combination with the pneumatic Swiss Lithoclast, can be used to fragment and remove large and hard bladder calculi.     

Percutaneous suprapubic cystolithotripsy for pediatric bladder stones in a developing country

OBJECTIVE: To evaluate our experience with percutaneous suprapubic cystolithotripsy (PCCL) in Yemeni children with endemic urinary bladder stones. PATIENTS AND METHODS: Between January 1993 and December 1998, 117 children underwent percutaneous suprapubic lithotripsy in Arabia Felix Modern Hospital, Sana'a Republic of Yemen. The patients' ages ranged from 8 months to 14 years (average 3.7 years). Ninety patients (77%) were under 5 years old; 20 patients (16%) were between 6 and 10 years old, and 7 patients (6%) were between 11 and 14 years old. There were 116 boys and 1 girl. The stone size ranged from 0.7 to 4 (average 2.3) cm. Five patients had coexisting urinary bilharziasis and another 5 patients had coexisting renal stone. In 10 patients, the stone was in the urethra. The procedure was done under general anesthesia. Dilation of the tract was made under fluoroscopy. The instrument was an adult 26-french nephroscope, the same as that used for percutaneous nephrolithotripsy. Ultrasound disintegration was needed for stones of > 1 cm. A suprapubic catheter was left for 24 h, and a urethral catheter was kept for 48 h. RESULTS: All patients became stone free. The average operating time was 15 (5-50) min. The average hospital stay was 2.7 (2-5) days. No severe intra- or postoperative complication was observed. The nucleus and/or the main component of the stones were ammonium acid urate in 109 patients (93%). CONCLUSION: Based on our experience we can conclude that percutaneous suprapubic lithotripsy is a safe and effective method for the treatment of bladder stones in children. It reduces morbidity and hospital stay and thus the cost of treatment. Our series proves the nutritional etiology of endemic pediatric bladder stones. To our knowledge, this is the largest series reported on percutaneous suprapubic management of endemic bladder stones in children.     

Percutaneous versus transurethral cystolithotripsy and TURP for large prostates and large vesical calculi: Refinement of technique and updated data

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.     

Transurethral resection of prostrate and suprapubic ballistic vesicolithotrity for benign prostatic hyperplasia with vesical calculi

Bladder calculi associated with benign prostatic hyperplasia are fairly common, and a popular treatment is transurethral resection of the prostate (TURP) with endoscopic lithotripsy as a combined procedure. We have been routinely using a Reuter's suprapubic trocar and cannula for continuous irrigation during TURP for medium-size and large glands. Rather than performing the vesicolithotripsy per urethra, we have found it easier and faster to use the suprapubic route, especially because the suprapubic tract was already partly made by the Reuter's trocar and half sheath. We describe the technique in detail and explain why we find it easier to extract the stone by the suprapubic rather than the urethral route.     

Improved suprapubic vesical drainage in transvesical prostatectomy.

An improved drainage is used in transvesical prostatectomy in order to avoid urinary retention after removal of the Novak-type suprapubic drainage with bladder neck cerclage haemostasis (described by some authors in 1975). The causes of urinary retention are analysed, the drainage technique as well as the mechanisms eliminating the above-mentioned complications are described.     

Evaluation of percutaneous suprapubic cystolithotripsy under local anesthesia

Objective  

To evaluate the feasibility and effectiveness of percutaneous cystolithotripsy under local anesthesia.     

Fused vesical calculi

A case is described in which a patient, who initially presented with five separate bladder calculi, was found to have had coalescence of three calculi to produce a large stone. This may be one mechanism in the development of a giant vesical calculus.     

Percutaneous nephrolithotomy for treating renal calculi in children

OBJECTIVE: To report our experience with the percutaneous management of renal stone disease in children. PATIENTS AND METHODS: The medical and radiological records of children up to 18 years old who were treated for renal calculi by percutaneous nephrolithotomy (PCNL) at our institution between March 1995 and April 2003 were reviewed. For stone removal a special paediatric 18 F access sheath was used. RESULTS: In all, 26 PCNLs were used in 23 patients (10 boys and 13 girls, aged 1.7-16.8 years). The presenting symptoms were urinary tract infection, abdominal pain and/or haematuria. Of the 23 patients, 17 (75%) had associated metabolic disease or underlying urological anatomical abnormalities. Urinary tract infections were found in 15 patients (65%). The mean (range) stone burden was 6.0 (0.5-18.2) cm2, and the operative duration 127 (50-260) min. The primary stone-free rate was 58%, which increased to 81% after treating residual fragments. One blood transfusion was required and one patient developed urosepsis after PCNL, which was treated with antibiotics. CONCLUSION: PCNL is an effective alternative for treating renal stones in children, and is the treatment of choice for stones refractory to extracorporeal shock wave lithotripsy.     

Multiple vesical calculi

A case of multiple vesical calculi is presented. There was no history of passing stones, although 1,368 were finally recovered from the bladder. The bladder was not grossly infected. The calculi were uric acid in composition and were not radio-opaque. Removal of the calculi, together with a very small vesical neck resection, provided complete relief of symptoms.

The management of vesical calculi with combined optical mechanical cystolithotripsy and transurethral prostatectomy: is it safe and effective?

OBJECTIVES: To investigate the effectiveness and reliability of the combination of optical mechanical cystolithotripsy (OMC) and transurethral prostatectomy (TURP) for the treatment of bladder calculi and obstructive benign prostatic enlargement (BPE). PATIENTS AND METHODS: From December 1990 to December 1996, 61 patients who had bladder stones and BPE or bladder neck contracture were treated with combined OMC and TURP; 32 patients who had bladder stones with no infravesical obstruction were treated with OMC alone. The records of a random selection of 97 patients with obstructive BPE who were treated with TURP only in the same period were used as the control. The operative duration time, the length of hospital stay, the duration of urethral catheterization, outcome and complications of the procedures for each patients were reviewed. The Mann-Whitney U-test and chi-square tests were used for statistical analysis. RESULTS: The mean duration of surgery, hospital stay and urethral catheterization were significantly longer with combined OMC and TURP than with OMC alone (P<0.05). Stone-free rates were 94% after OMC alone and 93% after combined OMC and TURP. The postoperative mean peak flow rates were 14.3 mL/s after the combined procedure and 15.2 mL/s after TURP alone. The complication rates were 21% for the combined procedure and 13% for OMC alone. The complication rate of TURP was 5%, significantly lower than that for the combined procedure (P<0.05). CONCLUSION: Bladder stones were associated with infravesical obstruction in two-thirds of patients. Simultaneous treatment with OMC and TURP did not change the effectiveness of these procedures, but caused additional morbidity.     

Giant vesical calculi in the female

We herein report a case of giant vesical calculi in the female bladder. To the best of our knowledge, these calculi represent the largest group of vesical calculi ever removed from the female bladder. The etiologic factors that contribute to bladder calculus formation in the female are discussed.     

Renal calculi. Percutaneous management

Percutaneous nephrolithotomy has established indications and is performed with high success and minimal morbidity. Patients who have large or hard stones or stones associated with urinary obstruction are candidates for a percutaneous procedure. When the certainty of the final result is important, the patient should have a PNL. In general, the best treatment for SWL failure is not more SWL; such patients usually should have an endoscopic procedure.
