Tale of Two: A ‘case report’ of two giant urinary bladder stones and recurrent anemia in a 78-year-old Filipino male

@#BACKGROUND: This is a rare case of two large urinary bladder stones causing severe infection of the urinary tract affecting the bone marrow due to chronic immune stimulation in a patient with recurrent anemia. Urinary bladder calculi are hard masses of minerals. They develop when the minerals in concentrated urine crystallize. This often happens when the bladder cannot be emptied. Signs and symptoms can vary from severe abdominal pain to blood in the urine. Sometimes, bladder stones don't cause any symptoms. If left untreated, bladder stones may lead to infections and other complications such as hepatic abscess via a hematogenous route. CASE: This is a case of a seventy-eight-year-old man with a history of multiple blood transfusions secondary to anemia of unknown cause. He came into our institution for a second opinion. We worked up the patient, which showed hepatic abscess and two large urinary bladder calculi. Further investigation of the anemia later led to a diagnosis of primary myelofibrosis. DIAGNOSTICS: Ultrasound showed a complex mass on the left hepatic lobe measuring 7.5 cm x 6.0 cm x 2.1 cm consistent with a hepatic abscess. The culture of the abscess was positive for E. coli. Computed Tomography (CT) scan of the lower abdomen showed heterogeneous mass measuring 8.6 cm x 8.7 cm x 9.2 cm within the urinary bladder (see Figure 2). Urinalysis was consistent with a urinary tract infection. Urine culture showed E. coli. Video-assisted cystoscopy showed two urinary bladder calculi, measuring 1.5 cm x 3.2 cm x 4.2 cm weighing 30 grams each (see Figure 3). The calculi were composed of 100% Calcium Oxalate. He underwent a series of diagnostic examinations for anemia including gastroscopy to rule out a bleeding ulcer. Complete blood count showed hemoglobin of 77 g/L and a hematocrit of 0.23. Finally, bone marrow core biopsy was done which is consistent with primary myelofibrosis. CONCLUSION: Urinary bladder stones can be asymptomatic and may present only with vague abdominal pain. It should be one of the considerations in asymptomatic patients with long-standing prostatitis or benign prostatic hyperplasia. Detailed history, thorough physical examinations, and cautious diagnostic tests are mandatory to confirm the diagnosis. A hepatic abscess may arise from infections in the urinary tract such as prostatitis through hematogenous extension. Therefore, it is important to address the origin of the infection to prevent such complications. This is a rare case of an elderly man who presented with chronic anemia and later found out to have large urinary bladder stones that caused severe infection leading to immune stimulation of the bone marrow, hence the diagnosis of primary myelofibrosis by bone marrow biopsy. Such a rare case must be thought of holistically and analytically.

Objective To evaluate the efficacy and safety of modified transurethral plasmakinetic enucleation of prostate (M-TPEP) combined with cystolithectomy in elderly patients with high risk of large volume benign prostatic hyperplasia (BPH) complicated with large urinary bladder calculi. Methods Seventy-one patients with high risk of large volume BPH complicated with large urinary bladder calculi were selected, and the patients were treated with M-TPEP combined with cystolithectomy. The operation time, intraoperative blood loss, hospitalization time, complications, and the maximum urinary flow rate (Qmax), post-void residual volume (PVR), serum potassium, international prostate symptom score (IPSS), quality of life (QOL) score preoperative and postoperative 3 months were recorded. Results Seventy-one patients successfully completed the operation, and no death occurred. The operation time was (75.48 ± 6.51) min, intraoperative blood loss was (82.63 ± 10.08) ml, and postoperative hospitalization time was 5-7 d. Incidence of intraoperative capsule perforation was 2.82% (2/71), incidence of postoperative temporary urinary incontinence was 7.04% (5/71), incidence of urethral and bladder irritation after operation was 8.45% (6/71), and incidence of postoperative wound infection was 2.82% (2/71). The PVR, IPSS and QOL score 3 months after operation were significantly lower than those before operation: (6.89 ± 0.74) ml vs. (205.13 ± 40.08) ml, (2.71 ± 0.45) scores vs. (28.62 ± 3.57) scores and (1.36 ± 0.24) scores vs. (4.93 ± 0.38) scores, the Qmaxwas significantly higher than that before operation: (22.46 ± 2.97) ml/s vs. (5.24 ± 0.43) ml/s, and there were statistical differences (P＜0.01);there was no statistical difference in serum potassium between before operation and 3 months after operation (P＞0.05). Conclusions M-TPEP combined with cystolithectomy has short operation time, quick recovery after operation and low complication rate. It is a proper operative method for the elderly patients with high risk of large volume BPH and large urinary bladder calculi.

Long-term Outcomes of Augmentation Cystoplasty in a Pediatric Population With Refractory Bladder Dysfunction: A 12-Year Follow-up Experience at Single Center / 대한배뇨장애요실금학회지

PURPOSE: Augmentation cystoplasty (AC) is a surgical procedure used in adults and children with refractory bladder dysfunction, including a small bladder capacity and inadequate bladder compliance, and in whom conservative and medical treatment has failed. This study was aimed to determine the long-term outcomes of AC in children. METHODS: A retrospective analysis was conducted of 42 patients (31 males; mean age, 14.2±6.2 years) who underwent AC for neurogenic and nonneurogenic bladder dysfunction, with a median 12.0±1.5 years of follow-up. All patients underwent AC using the ileum with or without continent reconstruction. Pre-AC, concurrent, and post-AC procedures and complications were analyzed. Patients who underwent ureterocystoplasty, were lost to follow-up, or had less than 10 years of follow-up were excluded. The primary outcomes were the complication and continence rates, the post-AC linear rate of height and weight gain, and renal function. The Student t-test was used to evaluate between-group differences and the paired t-test was used to evaluate longitudinal changes in measured variables. RESULTS: Renal function was stable or improved in 32 of 42 patients (76.2%), with a post-AC continence rate of 88.1%. Thirty patients (71.4%) required 72 procedures post-AC. There was no statistically significant difference in the mean percentile of height (P=0. 212) or weight (P=0.142) of patients in the pre- and post-AC periods. No cases of bladder perforation or malignancy were detected. CONCLUSIONS: We consider AC to be a safe and effective procedure that does not negatively affect future physical growth, while achieving a good rate of stable renal function. Patients need long-term follow-up to address long-term complications.

Litiasis vesical gigante en un paciente con hiperparatiroidismo primario: reporte de caso / Giant bladder lithiasis in a patient with primary hyperparathyroidism: report of a case

Se reporta el caso de un paciente con litiasis vesical gigante e hiperparatiroidismo primario. El hiperparatiroidismo primario se caracteriza por la producción autónoma de parathormonona, presentando hipercalcemia o calcio sérico normal-alto, con valores séricos de hormona paratiroidea elevados. El hiperparatiroidismo primario siempre debe ser tenido en cuenta en pacientes con historia de cálculos renales, nefrocalcinosis, dolor óseo, fracturas patológicas y resorción subperióstica. Se presenta caso de paciente masculino de 16 años de edad con antecedente de lito transuretral que acude a la emergencia por hematuria macroscópica y dolor abdominal suprapúbico. Se le realizó radiografía simple de pelvis, la que confirmó la presencia de litiasis vesical de grandes proporciones. Se reportó nivel de hormona paratiroidea de 335 pg/ml. Los pacientes con historia de cálculos de vías urinarias deben ser estudiados por patologías paratiroideas

We report the case of a patient with giant bladder lithiasis and primary hyperparathyroidism. This latter condition characterizes itself by the autonomous production of parathyroid hormone (PTH), leading to hypercalcemia or normal or elevated serum calcium levels, and there are also high values of PTH. Primary hyperparathyroidism must always be taken into account in patients with history of renal calculi, nephrocalcinosis, bone pain, pathological fractures, and subperiosteal reaction. The case is a 16-year old male patient with history of a previous transurethral procedure, who presented in the emergency room with macroscopic hematuria and suprapubic abdominal pain. A simple pelvis X-ray film was taken, which confirmed the presence of a large bladder calculus. The parathyroid hormone value was 335 pg/mL. Patients with history of renal calculi must be studied for determining the presence of parathyroid pathological conditions

To improve the effect of Chinese herbal decoction on patients with benign prostatic hyperplasia complicated with bladder stones of lower urinary tract symptoms after lithotripsy of bladder / 国际中医中药杂志

Objective To evaluate the improvement of lower urinary tract symptoms in benign prostatic hyperplasia (BPH) patients with bladder calculi by lithotripsy and adjuvant traditional Chinese decoction. Methods A total of 72 BPH patients with bladder calculi were recruited and randomly divided into the non-adjuvant treatment group (37 patients) and the adjuvant treatment group (35 patients). The adjuvant treatment group received adjuvant traditional Chinese decoction from 2 days before lithotripsy for 2 weeks. The maximum urinary flow rate (Qmax) , residual urine volume (RU), International Prostate Symptom Score (IPSS) and Quality of Life (QOL) were assessed before and after the treatment. The time of urine routine returned to normal and the indwelling time of catheter were compared between two groups. Urinary incontinence and recurrent bladder calculi were followed up for 6 months. Results After the treatment, the score of the IPSS (12.9 ± 4.5 vs. 15.7 ± 3.9;t=2.826, P=0.006) and the RU (47.3 ± 9.2 ml vs. 58.4 ± 11.3 ml;t=4.556, P<0.001) in the adjuvant treatment group were significantly lower than those in the non-adjuvant treatment group, and the Qmax (30.4 ± 4.7 ml/s vs. 21.4 ± 3.9 ml/s;t=8.862, P<0.001 ) was significantly higher. The indwelling time of catheter (5.7 ± 2.1 d vs. 8.1 ± 2.2d;t=4.730, P<0.001) and the time of urine routine returned to normal (6.9 ± 2.3 d vs. 10.2 ± 3.1 d;t=5.106, P<0.001) in the adjuvant treatment group were significantly shorter than those in the non-adjuvant treatment group. The 6-month follow-up showed that the incidence of urinary incontinence (2.9% vs. 18.9%;χ2=4.698, P=0.030) and recurrent bladder calculi (5.7% vs. 24.3%;χ2=4.813, P=0.028) in the adjuvant treatment group were significantly shorter than those in the non-adjuvant treatment group, and the total effective rate was significantly higher (62.9%vs. 29.7%; χ2=6.672, P=0.011). Conclusions Lithotripsy and adjuvant traditional Chinese decoction can reduce the IPSS score and RU, increase Qmax, decrease urinary incontinence and recurrent bladder calculi, and improve lower urinary tract symptoms in BPH patients with bladder calculi.

Concurrent stone stabilization improves ultrasonic and pneumatic efficacy during cystolithopaxy: an in vitro analysis

Objective To identify whether stabilization of larger bladder stones would improve the efficacy of combination (ultrasonic/pneumatic) lithotripsy in a phantom bladder stone model for percutaneous cystolithopaxy. Materials and Methods Using 1cm phantom Bego stones, a spherical model bladder was used to simulate percutaneous bladder access. A UroNet (US Endoscopy, USA) was placed alongside a Swiss Lithoclast probe through the working channel of a Storz 26Fr rigid nephroscope. Using a 30Fr working sheath, the stone was captured, and fragmented for 60seconds. Resulting fragments and irrigation were filtered through a 1mm strainer, and recorded. Five trials were performed with and without the UN. Durability was then assessed by measuring net defects, and residual grasp strength of each instrument. Descriptive statistics (mean, standard deviations) were used to summarize the data, and Student’s t-tests (alpha<0.05) were used to compare trials. Results The mean time to stone capture was 12s (8-45s). After fragmentation with UN stabilization, there were significant improvements in the amount of residual stone (22% dry weight reduction vs 8.1% without UN, p<0.001), number of fragments (17.5 vs 5.0 frag/stone, p=0.0029), and fragment size (3.6mm vs. 7.05 mm, p=0.035). Mesh defects were noted in all nets, ranging from 2-14 mm, though all but one net retained their original grip strength (36.8N). Conclusions Bladder stone stabilization improved fragmentation when used in conjunction with ultrasonic/pneumatic lithotripsy. However, due to limitations in maneuverability and durability of the UN, other tools need to identified for this indication. .

Outcomes of intracorporeal lithotripsy of upper tract stones is not affected by BMI and skin-to-stone distance (SSD) in obese and morbid patients

Purpose The purpose of this study is to determine if body mass index (BMI) and stone skin distance (SSD) affect stone free rate (SFR) in obese and morbid obese patients who underwent flexible URS for proximal ureteral or renal stones < 20 mm. Materials and Methods A retrospective chart review was performed of consecutive patients that underwent flexible URS. Inclusion criteria were: proximal ureteral stones and renal stones less than 20 mm in the preoperative computed tomography (CT). SFR were then compared according to SSD and BMI. Results A total of 153 patients were eligible for this analysis, 49 (32.02%) with SSD < 10 cm and 104 (67.97%) with SSD ≥ 10 cm. The mean stone size was 10.5 ± 6.4 mm. The overall SFR in our study was 82.4%. The SFR for the SSD < 10 and ≥ 10 were 79.6% and 83.7% respectively (p = 0.698) and for BMI < 30, ≥ 30 and < 40 and ≥ 40 were 82.9%, 81.7% and 90.9% respectively. Regression analysis showed no affect between BMI or SSD regarding SFR. Conclusion Ureteroscopy should be considered as a first-line of treatment for renal/proximal stones in obese and morbid obese patients. URS may be preferable to SWL in obese patients independently of the SSD, BMI or the location of proximal stones. .

Tratamento cirúrgico da litíase vesical: revisão de literatura / Surgical management of bladder stones: literature review

Cálculos vesicais são raros e a maioria dos casos ocorre em homens adultos com obstrução infravesical. Atualmente, existem poucos dados sobre o melhor tratamento desta doença. O objetivo desta revisão foi discutir alguns aspectos da patogênese e abordar o tratamento da litíase vesical. Uma ampla pesquisa na base de dados da "National Library of Medicine"/Pubmed foi realizada com os seguintes unitermos e descritores: vesical ou bexiga associados a cálculo, pedra ou litíase, e cistolitotripsia. Cento e setenta e um artigos foram identificados. Os artigos foram avaliados independentemente por dois revisores com experiência em urolitíase. Foram incluídos quando os resultados, complicações e seguimento foram claramente reportados. No final, 32 estudos preencheram os critérios de inclusão. Nota-se que diversas opções para o tratamento da litíase vesical estão disponíveis, porém não há estudos randomizados comparando-as. Diferentes taxas de pacientes livres de cálculo são descritas, sendo: litotripsia extracorpórea com ondas de choque (75-100%), cistolitotripsia transureteroscópica (63-100%), cistolitotripsia percutânea (89-100%) e cirurgia aberta (100%). O acesso percutâneo apresenta menor morbidade com resultados semelhantes ao tratamento transuretral, enquanto a litotrispsia extracorpórea apresenta as menores de taxas de eliminação de cálculos e fica reservada aos pacientes de alto risco cirúrgico.

Bladder stones are rare and most cases occur in adult men with bladder outlet obstruction. Currently, there are few data on the best treatment of this disease. The aim of this review is to discuss some aspects of pathogenesis and treatment approaches for bladder lithiasis. A comprehensive search of the database of the "National Library of Medicine" /pubmed was conducted with the following key words and descriptors: "bladder" or "vesical" associated with "calculus", "stone" or "lithiasis", and "cistolithotripsy ". One hundred and seventy-one articles were identified. The articles were independently assessed by two reviewers with expertise in urolithiasis. They were included in the study when the results, complications and follow-up were clearly reported. In the end, 32 studies met the inclusion criteria. Several options for the treatment of bladder lithiasis are available, but no randomized trials comparing them. Different rates of calculus-free patients are described in each of them, as follows: extracorporeal shock wave lithotripsy (75-100%), transurethral cistolithotripsy (63-100%), percutaneous cistolithotripsy (89-100%) and open surgery (100 %). The percutaneous approach has lower morbidity, with similar results to the transurethral treatment, while extracorporeal lithotripsy has the lowest rate of elimination of calculi and is reserved for patients at high surgical risk.

Objective To evaluate the lithotripsy efficiency of a newly calculi anchoring forceps in vitro.Methods Compared the efficiency with or without calculi anchoring forceps in the circumstances imitate percutaneous nephrolithotomy.There are 24 calculus for each group in random selection.The lithotripsy was completed by one people.the time,energy and retained calculus were compared by T-test.Results When the energy expenditure reaches 2 kJ,the operating time was (4.7 ± 0.9) min in group 1 and (4.2 ± 0.9) min in group 2 (P ＞ 0.05).The removal calculus showed no differences between the two groups (P ＞ 0.05).After the energy used over 2 k J,the operating time of the remained calculus were (4.5 ± 1.2) min in group 1 and (9.2 ± 2.6) min in group 2 respectively (P ＜ 0.05),and the energy consumed (1.7 ± 0.5) kJ and (2.6 ± 0.4) kJ respectively (P ＜ 0.05).Total energy consumed in group 1 and group2 was (3.7±0.5) kJ and (4.6±0.5) kJ (P＜0.05).And the cumulate time used was (9.2±1.7) min and (13.4 ±2.7) min in group 1 and group 2 respectively (P ＜0.05).Conclusions The calculi anchoring forceps can improve the efficiency of lithotripsy in vitro.The improvement was significant for the calculus whose diameter was smaller than lcm.

Percutaneous Nephrolithotomy for Staghorn Stones in Patients with Solitary Kidney in Prone Position or in completely Supine Position: a Single-center Experience

To evaluate the effectivity and safety of percutaneous nephrolithotomy (PCNL) in the treatment of solitary kidney with staghorn stones in prone position or in completely supine position.

We retrospectively reviewed the records of 18 patients with staghorn stones in a solitary kidney treated with PCNL. 12 patients underwent PCNL in prone position (group A). 6 patients underwent PCNL in completely supine position (group B). Demographic data, number of accesses, operating time, stone free rate, hemoglobin values, hospital stay and complications were studied. Serum creatinine, systolic and diastolic blood pressure, and new onset hypertension were determined preoperatively and postoperatively at 3 months.

No blood transfusions were required and no abdominal or thoracic organ injuries were reported in both groups. The mean operative time was 104 minutes (range:72-145 minutes) and 128 minutes (range:80-170 minutes), respectively. The I stage stone free rate was 91.7% and 83.3%, respectively. There was no new onset hypertension by the end of follow-up in both groups. Both groups showed a similar fall in serum creatinine at 3 month follow-up period (p = 0.004 and 0.029, respectively). Systolic blood pressure showed a statistically significant improvement in group B (p = 0.034).

PCNL is safe and has an acceptably high stone free rate in patients with solitary kidneys in both prone and completely supine position. At short-term follow-up, systolic blood pressure had improved in PCNL in supine position. .

Concomitant Laparoendoscopic Single-Site Surgery for Vesicolithotomy and Finger-Assisted Single-Port Transvesical Enucleation of the Prostate / 대한배뇨장애요실금학회지

Transurethral resection of the prostate is the most common surgery for benign prostatic hyperplasia. However, it doesn't work best for men with very large prostate and bladder stones. Herein we report our initial experience with concomitant laparoendoscopic single-site surgery and finger-assisted single-port transvesical enucleation of the prostate for the treatment of the condition.

Chemical and morphological analysis of kidney stones: a double-blind comparative study / Análise química e morfológica de cálculos renais: estudo comparativo duplo-cego

PURPOSE: To compare chemical to morphological kidney stone composition analysis based on a sample of 50 stones retrieved from patients at a nephrology service. METHODS: The chemical analysis was performed with a Bioclin® kit, while a 10-mm magnifying glass (10x; Prolabo, Paris, France) was employed in the morphological analysis. Findings obtained with the two methods were compared and classified as concordant (100 percent agreement), partly concordant (concordant for major components, discordant for minor components) or discordant (discordant for major components). RESULTS: In the chemical analysis, the most commonly observed major component was calcium (70 percent), followed by oxalate (66 percent), ammonium (56 percent), urate (28 percent) and carbonate (24 percent). In the morphological analysis, the most commonly observed major components were calcium phosphate and magnesium (32 percent each), followed by calcium oxalate monohydrate (24 percent), uric acid and urates (20 percent each), calcium oxalate dihydrate (18 percent) and cystine (6 percent). Infectious kidney stones were identified in 34 percent and 24 percent of cases by morphological and chemical analysis, respectively. Thirty-eight percent of the samples were classified as concordant, 52 percent were partly concordant and 10 percent were discordant. CONCLUSION: We suggest kidney stones be routinely submitted to both types of analysis for a better understanding of the mechanisms involved in lithogenesis.

OBJETIVO: Comparar a análise química com a análise morfológica de 50 cálculos urinários provenientes de pacientes em um serviço de nefrologia. MÉTODOS: A análise química foi realizada utilizando o kit da Bioclin®, enquanto que a morfológica foi realizada com auxílio de uma lupa de 10mm (Prolabo, Paris, France). A comparação entre as técnicas foi classificada em concordante (100 por cento de concordância), parcialmente concordante (componentes majoritários concordantes e minoritários discordantes) e discordante (discordância nos componentes majoritários). RESULTADOS: Na análise química os principais componentes majoritários foram cálcio (70 por cento), oxalato (66 por cento), amônio (56 por cento), urato (28 por cento) e carbonato (24 por cento). Na análise morfológica os principais componentes majoritários foram fosfato cálcico (PCa) e magnesiano-PCa (32 por cento), oxalato de cálcio monohidratado (24 por cento), ácido úrico e uratos (20 por cento), oxalato de cálcio dihidratado (18 por cento) e cistina (6 por cento). Cálculos de infecção foram identificados em 34 por cento e 24 por cento casos pela análise morfológica e química, respectivamente. Concordância total foi observada em 38 por cento, concordância parcial em 52 por cento e discordância em 10 por cento. CONCLUSÃO: Sugere-se a utilização simultânea das duas técnicas para melhor compreensão dos mecanismos litogênicos.

Surgical Clip-Related Complications after Radical Prostatectomy

PURPOSE: The aim of this study was to describe the surgical clip-related complications that can occur after open retropubic prostatectomy (RRP), pure laparoscopic prostatectomy (LRP), and robot-assisted laparoscopic radical prostatectomy (RALP). MATERIALS AND METHODS: A database of 641 patients who underwent RRP (n=439), LRP (n=49), and RALP (n=153) at our institution between January 2006 and April 2009 was reviewed to identify patients with complications related to the use of surgical clips. The median follow-up time for the entire cohort was 19.0 months (range, 1-42 months). RESULTS: Of the 641 patients, 25 (5.7%), 1 (2.0%), and 2 (1.3%) had a bladder neck contracture after RRP, LRP, and RALP, respectively. Two RRP patients had a bladder stone. In total, 6 patients had surgical clip-related complications. Metal clip migration was associated with 2 (8%) of the 25 RRP cases of bladder neck contracture and both (100%) of the RRP cases of bladder stone. Moreover, both (100%) of the RALP cases of bladder neck contractures were associated with Hem-o-lok clip migration into the anastomotic site. CONCLUSIONS: Surgical clips are prone to migration and may cause, or significantly contribute to, bladder neck contracture or the formation of bladder stones after radical prostatectomy. These findings also suggest that because the incidence of bladder neck contracture after RALP is low, the migration of Hem-o-lok clips should be suspected when voiding difficulty occurs after RALP.
