ABSTRACT
OBJECTIVE: To evaluate the efficacy and complications of extracorporeal lithotripsy (SWL) as a first-line treatment for renal and ureteral stones METHODS: Retrospective and observational study of all the patients treated with lithotripsy in a third level center between January 2014 and January 2021; characteristics of the patients, the stones, complications and results of SWL is recollected. Multivariate logistic regression of the factors associated with stone size reduction was performed. A statistical analysis of the factors associated with additional treatment after SWL and factors associated with complications is also executed. RESULTS: 1727 patients are included. Stone mean size was 9,5mm. 1540 (89.4%) patients presented reduction in stone size. In multivariate analysis, stone size (OR=1.13; p=0.00), ureteral location of the lithiasis (OR=1.15; p=0.052) and number of waves (p=0.002; OR=1.00) used in SWL are the factors associated with reduction of stone size. Additional treatment after lithotripsy was needed in 665 patients (38.5%). The factors associated with the need for retreatment were stone size (OR=1.131; p=0.000), number of waves (OR=1.000; p=0.000), energy (OR=1.005; p=0.000). 153 patients (8.8%) suffered complications after SWL. A statistically significant association was found between the size of the lithiasis (p=0.024, OR=1.054) and the previous urinary diversion (P=0.004, OR=0.571). CONCLUSION: Lithotripsy remains an effective treatment as the first line of therapy for reno-ureteral lithiasis with a low percentage of complications.

INTRODUCTION: The use of extracorporeal shock wave lithotripsy (ESWL) for lower calyx stones is associated with a high rate of residual fragments. Our aim is to analyse the effectiveness and complications of ESWL for lower calyx stones. METHODS: Retrospective review of patients with lower renal calyx stones treated with ESWL between January-2014 and December-2020. Measurement of infundibular length, infundibular width and infundibulopelvic angle in lower renal pole to determine favourable anatomy. ESWL failure: fragments >3 mm detected in plain abdominal film, CT scan and/or renal ultrasound 3 months after treatment. Complications after ESWL, auxiliary procedures along with risk factors associated with perirenal haematoma were analysed. SPSS statistical software was used. RESULTS: 512 patients with lower calyx stones were treated with ESWL. 80.3% of patients had a favourable anatomy. Overall stone-free rate was 70.5%. Regarding main complications after ESWL, stainstrasse was described in 5 patients and urinary tract infection in 3 patients. 10 perirenal haematomas (2%) were reported. Statistical association was found between antiplatelet treatment and the risk of perirenal haematoma (p = 0.004). Logistic binary regression proved the association between unfavourable anatomy of the lower renal pole (p = 0.000), size of the stone (p = 0.001), number of shock waves (p = 0.003), energy applied (p = 0.038) and the need for additional treatment after ESWL. CONCLUSIONS: ESWL can still be considered as the initial treatment option for lower renal pole stones. The size of the stone, an unfavourable anatomy of the lower renal calyx, number of shock waves and energy applied can help predict the need for additional treatment.

Introduction: The aim was to determine the impact of COVID-19 pandemic on urolithiasis presentation and management. Methods: In this retrospective study, we comparatively evaluated urgent and elective procedures due to urolithiasis during the early 8 months of the COVID-19 pandemic (March 1, 2020, to October 31, 2020) compared to the same period a year before, and between waves. Fisher's exact test, Student's t-test, chi-square test and Mann-Whitney U test were used to compare the patients' characteristics and outcomes between the 2 periods and waves. Results: Five hundred and thirty procedures were included. The overall numbers of surgical procedures due to urolithiasis were similar between pre-pandemic and pandemic periods. Regarding elective surgery, our data draw attention to the increased complication rate in the pandemic times, but no statistically significant differences in terms of types of procedures and need for complementary treatments were observed. We noted that patterns of presentation of complicated renal colic were different during COVID-19 pandemic, with a higher number of days after the onset of symptoms and a higher proportion of patients presenting acute kidney injury. Furthermore, a significant increase of creatinine levels at presentation in first wave was detected, and a growth in the number of urgent procedures after the first wave was noted, owing to the delay in urolithiasis treatment and diagnosis. Conclusions: The COVID-19 pandemic has negatively affected both urgent and elective management of urolithiasis. Lessons about the management of urolithiasis in this context should be learned to avoid fatal complications and improve standards of care.

INTRODUCTION AND OBJECTIVE: The association of the metabolic syndrome with lithogenesis has been described, especially in uric acid stones. The aim of the work was to analyze the role of the metabolic syndrome in oxalocalcic lithogenesis. MATERIALS AND METHODS: Metabolic evaluation of 151 patients including biochemical, hormonal and 24-urine urine parameters, as well as characteristics associated with metabolic syndrome. The relationship between the characteristics associated with the metabolic syndrome and those related to lithogenesis was evaluated using Spearman's correlation coefficient (SCC), Student's t test and Fisher's exact test. RESULTS: The average body mass index (BMI) was 25.9 (SD 3.7). The median age was 51 years (18.6-84.8) and 64.9% were men. There were no statistically significant differences between hypertension and estradiol, testosterone, triglycerides or cholesterol (P=.191, .969, .454, .345, respectively). Regarding glucose, the mean was 114.5 and 93.5mg/dl in patients with and without hypertension (P=.000). The levels of glucose, estradiol, testosterone or cholesterol did not vary with proteinuria (P=.518, P=.227, P=.095, P=.218, respectively). The mean triglycerides were 185.6 and 108.2mg/dl in patients with and without proteinuria (P=.001). Hypertension and proteinuria were not associated (P=.586). BMI correlated with serum and urinary uric acid and urinary creatinine. CONCLUSIONS: There are few associations between the characteristics of the metabolic syndrome and the anomalies related to lithogenesis. Metabolic syndrome does not seem to have a relevant role in the development of oxalocalcic stones.

BACKGROUND: Xanthogranulomatous pyelonephritis (XGP) is an inflammatory condition of the kidney and its treatment most often involves a combination of antibiotics and nephrectomy. This study aimed to define the clinical features and management of XGP, focusing on microbiological aspects and antibiotic therapy. METHODS: We performed a retrospective study of 27 cases of XGP diagnosed between January 2001 and January 2020 to analyse their clinical and management characteristics. In addition, a literature review was conducted of XGP case series covering the period from 2000-2020. We searched PubMed for case series through April 2020 without language restrictions. Studies reporting case series of XGP (more than ten cases) were included if they were relevant to this study. RESULTS: Twenty-seven patients were diagnosed with XGP, and 26 of them were histologically proven to have XGP. A total of 81.5% of the patients were female and the mean age was 59.6 years (SD 19.2). The most frequent symptoms were flank pain (70.4%) and fever (59.3%), while 77.8% of patients had renal stones. Proteus mirabilis was detected in the urine culture in 18.5% of patients, followed by detection of Escherichia coli in 14.8% of patients. The computed tomography (CT) findings included perirenal (29.6%) or pararenal (29.6%) involvement in the majority of patients. Twenty-six patients underwent nephrectomy. Piperacillin/tazobactam and ceftriaxone were the most commonly prescribed antibiotics for treatment. The reported piperacillin/tazobactam and ceftriaxone resistance rates were 14.3% and 16.6%, respectively. Twenty-six case series were included in the literature review, reporting 693 cases in total. CONCLUSION: We found well-established characteristics of XGP patients among series in terms of previous history, clinical, laboratory and imaging findings, and operative and postoperative outcomes. It is important to know the clinical presentation and potential severity of XGP, as well as the most frequently involved microorganisms and their antibiotic resistance profiles, to select the most appropriate antibiotic therapy.

Intraparenchymal renal artery aneurysms are uncommon and represent less than 10% of all renal artery aneurysms. They are caused by trauma or iatrogenic injury, and their rupture can lead to life-threatening hemorrhage. We report the case of a 48-year-old male with history of left solitary kidney and orthotopic neobladder, who presented with massive hematuria 7 days after nephrostomy tube placement because of obstructive uropathy and acute renal failure due to ureteroileal stricture. An abdominal CT angiography revealed an intraparenchymal renal artery aneurysm, and it was successfully treated with superselective endovascular embolization, achieving maximal parenchymal preservation.
ABSTRACT
OBJECTIVE: To evaluate the incidence, clinical presentation and factors associated with the development of urinary sepsis after performing ureterorenoscopy. MATERIAL AND METHODS: Retrospective study of patients undergoing ureterorenoscopy for the treatment of lithiasis between July 2015 and October 2017. Patients who developed urinary sepsis during the 30 days following the intervention were identified. Personal, clinical, surgical and microbiological backgrounds were collected. Statistical analysis was performed with the Chi squared test (or Fisher's exact test), Student's t (or U Mann-Whitney) or logistic regression as appropriate. RESULTS: 246 ureterorenoscopies were performed, 184 (74.8%) on ureteral stones and 62 (25.2%) on kidney stones, with a mean age of 52 (44.5-59.5) years. After procedure, 18 (7.3%) patients developed urinary sepsis, 10 of them (55.5%) occurred in the first 24h. The urine culture showed enterobacteria (61.1%) and enterococci (38.9%). The antibiogram showed greater sensitivity to nitrofurantoins (100%) and quinolones (72%). The statistical analysis showed that female sex, the clinical debut of urolithiasis as urinary sepsis, having received antibiotic or having required urinary diversion by a double J during debut, positive presurgical uroculture and the persistence of residual lithiasis after surgery were significantly associated (P<.05) with the development of urinary sepsis after ureterorenoscopy. CONCLUSION: Urinary sepsis is a complication that appears after performing ureterorenoscopy, especially in female patients with a history of urinary sepsis, antibiotic therapy, double J, previous positive urine culture or residual lithiasis after the procedure.

CONTEXT AND OBJECTIVES: The first-line treatment for >2cm lithiasis is percutaneous nephrolithotomy (PNL), leaving flexible ureteroscopy (fURS) as a second option. In the present review, the stone-free rate and the complications of both techniques were evaluated in the treatment of 2-3cm stones. MATERIAL AND METHODS: Systematic review of studies that compared both techniques. Studies that were not comparative, as well as those carried out in the pediatric population or with <2cm or>3cm stones, were excluded. Two researchers independently performed the investigation, obtaining 5 studies that made up a total of 815 patients: 252 belonged to the fURS group and 563 to the PNL group. Four studies were retrospective, and one was non-randomized prospective. RESULTS: Stone-free rate ranged between 47.0% and 95.0% for the fURS and between 87.0% and 100% for the PNL. The complication rate was 8.8-29.0% in the fURS and 11.9-27.0% in the PNL. fURS required a greater number of procedures, and had a lower decrease in haemoglobin and creatinine rise compared to PNL. CONCLUSIONS: The stone-free rate was higher for PNL, although the fURS could reach comparable results at the expense of performing several procedures. Both techniques have a similar frequency of complications, but the PNL has more postsurgical analytical alterations.

CONTEXT AND OBJECTIVE: The increasingly early diagnosis of prostate cancer requires a search for therapeutic alternatives with good oncological results that in turn facilitate a good long-term quality of life. This review analyses 2 minimally invasive therapies for treating localised prostate cancer in terms of oncological and functional results, as well as the complications resulting from the therapies. ACQUISITION OF EVIDENCE: A systematic literature review was conducted of the treatment of localised prostate cancer with 2 ablative techniques as the primary therapy: cryosurgery or cryotherapy and high intensity focused ultrasound (HIFU). We included patients who underwent procedures that included the entire gland, with hemiablation or focal therapy, which were indicated for low to intermediate-risk prostate cancer according to the D'Amico criteria. We excluded patients with high-risk prostate cancer and those who underwent any prior treatment for prostate cancer. SYNTHESIS OF THE EVIDENCE: After conducting the literature search and excluding the studies that did not meet the protocol criteria, we reviewed a total of 14 studies, with a total of 350 patients treated using cryotherapy and 1107 treated with HIFU. All studies were either prospective or retrospective and were not randomised. The patients' mean age was younger than 75 years. Overall, the rate of disease recurrence in the patients treated with cryotherapy varied between 13.2% and 26%, while the rate for those treated with HIFU varied between 7.3% and 67.9%. The overall demonstrated continence at 12 months was 97.6-100% for cryotherapy and 96-100% for HIFU. In terms of sexual potency rates, cryotherapy showed complete potency at 12 months for 86-100% of the patients treated with focal cryotherapy and slightly lower rates for hemiablation (76.9-100%) and total therapy (39%). HIFU showed potency rates of 89%, 52-80% and 33-78% for focal therapy, hemiablation and total therapy, respectively. CONCLUSIONS: Both techniques have comparable functional results, although the somewhat poorer oncological results for HIFU reflect a steeper learning curve, which could lead to its use in centres with high volumes of patients.
ABSTRACT
Purpose. Published data about cryotherapy for prostate cancer (PC) treatment are based on case series with a lack of clinical trials and the inexistence of a validated definition of biochemical failure. A prospective study with standardized followup protocol was conducted in our institution. Material and Methods. Prospective study of a series of cases including 108 patients diagnosed with localized PC at clinical stage T1c-T2c treated by primary cryoablation and median followup of 61 months. Criteria of biochemical recurrence were unified according to the American Society for Therapeutic Radiology and Oncology (ASTRO). End points were biochemical progression-free survival (BPFS), cancer-specific survival, and overall survival. Rate of complications was reported. Results. The BPFS for low-, medium-, and high-risk patients was 96.4%, 91.2%, and 62.2%, respectively. Cancer-specific survival was 98.1%. Overall survival reached 94.4%. Complications included incontinence in 5.6%, urinary tract obstruction in 1.9%, urethral sloughing in 5.6%, haematuria in 1.9%, perineal pain in 11.1%, and prostatorectal fistula in 0.9%. Erectile disfunction was found in 98.1%. Conclusions. Cryotherapy is an effective and minimally invasive treatment for primary PC in well-selected cases, with low surgical risk and good results in terms of BPFS, cancer-specific survival, and overall survival.
ABSTRACT
INTRODUCTION: The TVT system is the most common surgical technique of female stress urinary incontinence, because of the simplicity. good clinical results and rare complications. MATERIAL AND METHODS: From april, 1999 to march. 2004, it has been done in our department 100 TVT systems with the revision of the result over the six following months. The average follow-up rate was 10.36 months (R: 1-54 months) and looses mean the 11% of the cases. All the patients presented stress incontinence and their average age was 56.6 years old (30-80). The 12% of the cases have been previously operated of urinary incontinence. 21 patients presented previous surgery of pelvic floor. In the 17% of the cases, TVT systems was associated to another surgical technique: 15% of them was operated of cystocele, 1% of them had surgical correction of rectocele, 1% of them had a strong surgery of pelvic floor, that included TVT system, correction of pelvic floor and hysterectomy. RESULTS: We obtained 65% of successful cases, defined as objective confirmation of absence of looses from the observer and the subjective reference of the patient: 17% of clear improvement (clear decrease of looses from the patient and subjective improvement) and 7% of failure of the technique. The total percentage of appearance of novo post-surgery urgency is 9%. There were complications in the 12% of the cases: there were three cases of bladder perforation, two of them intra-operative and one of them deferred and associated to an infection of surgical wound; another three cases of residue in the immediate post-operative that were resolved with bladder catheterization: one case of acute urinary retention that was treated with bladder catheterization with suprapubic cistostomy: one case of chemical peritonitis corrected with a conservative treatment; two cases of vaginal extrusion of sling, which were resolved with the section of the outer sling; one patient presented a hipogastric hematoma resolved with conservative measures: and one patient presented pelvic discomfort with spontaneous resolution. CONCLUSIONS: We consider the TVT system as an effective surgical technique in the treatment of the female stress urinary incontinence. It is a simple technique with a short stay in the hospital and rare complications.

OBJECTIVE: To identify a potential relationship between two variables, risk of metastasis and use of imaging techniques, in an extension study in prostate cancer patients diagnosed in the Autonomous Community of Madrid in 2000. MATERIAL AND METHODS: 1,127 patients with available data on the tumour extension study were analysed. Performance and non performance of bone scans and CTs were correlated to risk variables for developing metastasis as described in the literature (PSA, Gleason and stage) and to therapy administered. RESULTS: The proportion of patients with risk variables for metastasis when bone scans were performed was between 7% to 14% greater than in patients with no variables. No differences were seen for CTs based on risk variables. With matching risk variables, more imaging techniques were used in patients receiving radiotherapy that in those managed with prostatectomy. CONCLUSION: Based on current recommendations imaging techniques were used in excess in the extension study in patients with no risk variables for metastasis. Conduct of a further study in the Autonomous Community seems advisable to confirm the likelihood of implementing such recommendations considering our prevalence of metastatic disease.

OBJECTIVE: To know the therapeutic options used in patients diagnosed with prostate cancer in the Autonomous Community of Madrid in 2000. MATERIAL AND METHODS: The study was conducted on 1,745 patients referred by hospitals taking part in the study. Data on treatment used was available for 1,104 (63%) patients. Treatment modality was correlated to clinical stage and patient age. RESULTS: Most frequent choice was hormone therapy (35%) followed by radical prostatectomy (34%) and radiotherapy (25%). Prostatectomy was most commonly used in patients with localised (42.3%) disease while hormone therapy was preferred for locally advanced (45.6%) or disseminated (94%) disease. There are significant differences in therapeutic indications between the various Health areas participating in the survey. Median age of patients with localised and locally advanced disease was lower in patients managed with prostatectomy (65 and 64 years, respectively) than in those managed with radiotherapy (70 and 69 years, respectively). CONCLUSION: The therapeutic modality indicated by urologists in the Madrid Autonomous Community for managing patients with prostate cancer generally meets with literature recommendations.

OBJECTIVE: To know the incidence in the year 2000 of prostate cancer in the Autonomous Community of Madrid and its breakdown by Health Areas. MATERIAL AND METHOD: Study of histologically confirmed prostate cancer case reports and retrospective data acquisition for 2000 in the Autonomous Community of Madrid, both from Public and Private Health Care hospitals. RESULTS: Gross incidence of prostate cancer in the Autonomous Community of Madrid was 100.4 cases per 100,000 males. The incidence adjusted for the Spanish, European and Worldwide population was 120.1, 103.5 and 68.6 cases per 100,000 males, respectively. Mean age at diagnosis was 70 +/- 7.8 (40-94) years, median of 70 years. The age group with higher incidence was 70 to 79 years. CONCLUSIONS: The incidence of prostate cancer in the Autonomous Community of Madrid is lower than that in the US but higher than in most countries or regions in the EU. The different way of using PSA testing in the Health Areas of the Autonomous Community may explain the differences seen in terms of incidence by Area.

OBJECTIVE: To know the presentation form, diagnostic method and clinical stage at the time of diagnosis in subjects with prostate cancer (PC) in the Autonomous Community of Madrid in 2000. MATERIAL AND METHOD: Data from 1745 patients with histologically confirmed prostate cancer obtained from 15 Hospitals participating in the study was analysed. The variables studied were: associated disease, reason for visiting the hospital, digital rectal examination (DRE), PSA, diagnostic method, graded Gleason score, tests performed in the tumoral extension study and tumour staging. The qualitative variables are given in percentages of the overall number and the quantitative variables are expressed as the median, standard deviation, maximum and minimum values and 25%, 50% (median) and 75% percentiles. RESULTS: 67% cases had an associated disease. In most (75%) patients the reason for visiting the hospital was prostatic syndrome. DRE revealed that 42.7% has no tumour. At the time of diagnosis half the patients had PSA levels lower than or equal to 11 ng/ml. Transrectal ultrasound-guided biopsy was used for diagnosis in 93% subjects. The most commonly reported Gleason scores were 6 (31.3%) and 7 (28.7%). In 75% subjects the disease was considered to be clinically limited to the prostate, in 12.5% locally advanced and in 12.5% metastatic. CONCLUSIONS: Most patients came to the hospital because of symptoms not related to PC. Transrectal ultrasound-guided biopsy is confirmed as the choice technique for PC diagnosis. When a comparison is made to historical series in our Autonomous Community a pattern of earlier diagnosis can be seen.

We report the case of a 20-year old male with a right testicular tumor. Bilateral orchidectomy was practised considering the synchronous clinical, ultrasonographical and histological (intraoperative biopsy) findings of the left testis. The definitive pathological report showed a right embryonal carcinoma with wide intratubular germ cell neoplasia (IGCN) of the contralateral testis. IGCN (formerly carcinoma in situ) is present in about 5% of cases in the contralateral gonad of those patients with a testicular neoplasm. More than 50% will develop cancer in that testis. Clinical and physical examination findings are usually unspecific. The diagnosis of IGCN is based on biopsy, although ultrasonography could give some data too, as some authors report. We analyze the therapy options for IGCN: (orchidectomy, chemotherapy, radiotherapy, or "wait and see"). In our case, the first one was made. Chemotherapy was used due to existence of retroperitoneal lymph node metastases, with an excellent follow-up afterwards.

OBJECTIVES: To analyze the incidence of lithiasis and stone composition in our setting. The trend is compared with the results of the majority of studies on urinary calculi reported in the literature based on the number and composition of stones. METHODS: The study comprised patients referred to the Urolithiasis Unit of our hospital over the last 21 years. Stone composition was analyzed by infra-red spectroscopy. The study period was divided into 4 time intervals: 1977-1979, 1977-1980, 1977-1987 and 1977-1998 in order to determine the trends of the incidence of lithiasis in our setting. RESULTS: A total of 5516 patients were reviewed; of these, 766 had recurrence. The distribution was 385, 995, 3378 and 5516, respectively. Calcium oxalate calculi showed an incidence of 61.3%, calcium phosphate 18.5%, uric acid 11.2%, infectious calculi (ammonium urate and ammonium magnesium phosphate) 6.6%, and finally the incidence of cysteine calculi was 0.77%. Concerning the distribution according to sex, 62% of the males had calcium oxalate stones, 68% uric acid, 42.5% phosphate and 45% infectious lithiasis. The trends for uric acid, infectious, oxalate and phosphate calculi changed over time. CONCLUSIONS: There is a clear trend of calculi prevalence in the male, particularly oxalate and uric acid calculi. There is a trend for cysteine calculi to remain the same, calcium phosphate and oxalate calculi to increase, and uric and infectious calculi to decrease. The changes observed may be due to dietary changes and improvement in the quality of life.

OBJECTIVE: To determine the telomerase activity in urine samples of patients with superficial bladder cancer, its sensitivity and specificity as a tumor marker, and possible implications for prognosis, diagnosis and therapeutic efficacy. METHODS: Urine samples of 50 patients with superficial bladder cancer were analyzed. Telomerase activity was determined by TRAP (telomeric repeat amplification protocol). Standard urinary cytology, urine culture and urinary sediment analysis were performed, as well as a pathological analysis of the surgical specimen. RESULTS: 84% of the patients were positive for telomerase activity and only 52% had a positive cytology. Telomerase activity showed a sensitivity and specificity of 73.6% and 92.7%, respectively, versus 53.2% and 81.8% for urinary cytology. The degree of cell differentiation and, to a lesser extent, bladder wall infiltration showed differences in comparison with conventional urinary cytology. CONCLUSIONS: Telomerase activity can be determined in voided urine samples of patients with superficial bladder cancer. It has a higher sensitivity and specificity than conventional urinary cytology and is a good marker for diagnosis and follow-up of these patients.
