RESUMO
This study describes the clinical profile, operative findings, surgical technique, type of implant and complications encountered in implantation of abnormal cochlea by the transcanal (veria) technique in a tertiary care centre. This is a retrospective study done amongst 337 patients who underwent cochlear implantation by veria technique between January 2013 to August 2023. Based on pre-operative imaging with high-resolution computed tomography and magnetic resonance imaging the cochleovestibular malformations in this study were classified according to Sennaroglu classification and the cochlear ossification was graded from I to IV. Amongst the 337 patients who underwent cochlear implantation during the study period there were 79 cases (23.4%) with abnormalities of cochlea. This included 45 patients (13.4%) with congenital malformations, 20 patients (5.9%) with cochlear fibrosis and 14 patients (4.2%) with cochlear ossification. The commonest cochlear malformation was Incomplete Partition 2 which was present in 21 patients (46.7%). The other common malformations were cochlear hypoplasia (31.1%), Incomplete Partition 1(13.3%) and common cavity (8.9%). Out of the 20 patients with cochlear fibrosis, 17 patients had fibrosis only in the basal turn. Out of the 14 patients with cochlear ossification 8 patients (57.1%) had a grade 1 ossification, 2 patients (14.3%) had a grade 2 ossification and 4 patients (28.6%) had a grade 3 ossification. One of the patients required re-exploration for correcting the placement of electrode. The type of implant were chosen depending on individual malformation or length of ossification and fibrosis. In the past, inner ear anomalies were considered as a contraindication for cochlear implantation however it is now possible to implant most of these abnormal cochlea by careful planning, a modification of the surgical technique and the type of electrode used.
RESUMO
INTRODUCTION: Recent AUA guidelines for the management of benign prostatic hyperplasia (BPH) recommend routine collection of the International Prostate Symptom Score (IPSS) data, but routine collection can be challenging to fully implement. We investigated the impact of distributing the IPSS by electronic patient portal (EPP) on IPSS completion and its impact on BPH management. METHODS: We performed a retrospective, longitudinal study of men undergoing a new patient visit (NPV) for BPH at our academic medical center. From September 2019 to November 2022, we identified patients undergoing an NPV for BPH. Prior to January 2021, the IPSS was collected in person at NPVs via paper forms; afterwards, the IPSS was distributed before the NPV using the EPP. Our primary outcome was IPSS completion; secondary outcomes were new BPH medications and BPH surgery ordered within 6 months. RESULTS: We identified 485 patients who underwent an NPV for BPH. EPP implementation significantly increased IPSS questionnaire completion (36.5% vs 56.9%, P < .0001). Following EPP implementation, we found that new BPH medications ordered at time of NPV decreased (10.4% vs 4.7%, P = .02). Although BPH surgery ordered within 6 months was similar, patients following EPP implementation had shorter time to BPH surgery compared to prior. CONCLUSIONS: Our study revealed that EPP distribution of the IPSS improves IPSS collection compliance, aligning our practice closer with AUA guidelines. Routine collection of the IPSS may impact clinical practice through the detection of more severe BPH, which reduces medical BPH management and time to definitive BPH therapy. Further work is needed to confirm findings.

Introduction: Chemical composition analysis is important in prevention counseling for kidney stone disease. Advances in laser technology have made dusting techniques more prevalent, but this offers no consistent way to collect enough material to send for chemical analysis, leading many to forgo this test. We developed a novel machine learning (ML) model to effectively assess stone composition based on intraoperative endoscopic video data. Methods: Two endourologists performed ureteroscopy for kidney stones ≥ 10 mm. Representative videos were recorded intraoperatively. Individual frames were extracted from the videos, and the stone was outlined by human tracing. An ML model, UroSAM, was built and trained to automatically identify kidney stones in the images and predict the majority stone composition as follows: calcium oxalate monohydrate (COM), dihydrate (COD), calcium phosphate (CAP), or uric acid (UA). UroSAM was built on top of the publicly available Segment Anything Model (SAM) and incorporated a U-Net convolutional neural network (CNN). Discussion: A total of 78 ureteroscopy videos were collected; 50 were used for the model after exclusions (32 COM, 8 COD, 8 CAP, 2 UA). The ML model segmented the images with 94.77% precision. Dice coefficient (0.9135) and Intersection over Union (0.8496) confirmed good segmentation performance of the ML model. A video-wise evaluation demonstrated 60% correct classification of stone composition. Subgroup analysis showed correct classification in 84.4% of COM videos. A post hoc adaptive threshold technique was used to mitigate biasing of the model toward COM because of data imbalance; this improved the overall correct classification to 62% while improving the classification of COD, CAP, and UA videos. Conclusions: This study demonstrates the effective development of UroSAM, an ML model that precisely identifies kidney stones from natural endoscopic video data. More high-quality video data will improve the performance of the model in classifying the majority stone composition.

Holmium laser enucleation of the prostate (HoLEP) is a size-independent option for benign prostatic hyperplasia surgical management. Since lower urinary tract symptoms (LUTS) are a quality-of-life issue, studies should prioritize patient-reported outcomes (PROs). This HoLEP review assesses PROs inclusion in the top 20 cited HoLEP studies and defines their limitations. PROs were categorized by domain: LUTS, incontinence, sexual function, pain, hematuria, and patient satisfaction. On review, no top-cited study included all PRO domains. The nuanced patient experience after HoLEP could be better defined via standardized utilization of validated PROs, while also improving comparability between HoLEP studies.

Pediatric nephrolithiasis is increasing in incidence and presents differently compared to adults. We report a case of nephrolithiasis in a pediatric patient, presenting with complaints of emesis, anuria, hematuria, and abdominal distension, leading to a diagnosis of bilateral obstructing cystine stones requiring bilateral percutaneous nephrolithotomy. Pediatric patients with anuria should be evaluated for bilateral nephrolithiasis as an etiology. Calculous anuria requires prompt recognition of the pathologic process and relief of the obstruction with close follow-up and supportive care until definitive stone management. Bilateral percutaneous nephrolithotomy can provide definitive surgical intervention without significant morbidity.

Objective: National guidelines recommend periprocedural antibiotics before percutaneous nephrolithotomy (PCNL), yet it is not clear which is superior. We conducted a randomized trial to compare two guideline-recommended antibiotics: ciprofloxacin (cipro) vs cefazolin, on PCNL outcomes, focusing on the development of systemic inflammatory response syndrome (SIRS) criteria. Methods: Adult patients who were not considered high risk for surgical or infectious complications and undergoing PCNL were randomized to receive either cipro or cefazolin perioperatively. All had negative preoperative urine cultures. Demographic and perioperative data were collected, including SIRS criteria, intraoperative urine culture, duration of hospitalization, and need for intensive care. SIRS is defined by ≥2 of the following: body temperature <96.8°F or >100.4°F, heart rate >90 bpm, respiratory rate >20 per minute, and white blood cell count <4000 or >12,000 cells/mm3. Results: One hundred forty-seven patients were enrolled and randomized (79 cefazolin and 68 cipro). All preoperative characteristics were similar (p > 0.05), except for mean age, which was higher in the cipro group (64 vs 57 years, p = 0.03). Intra- and postoperative findings were similar, with no difference between groups (p > 0.05), except a longer mean hospital stay in the cefazolin group (2 hours longer, p = 0.02). There was no difference between SIRS episodes in both univariate and multivariate analyses. Conclusions: Despite the relatively broader coverage for urinary tract pathogens with ciprofloxacin, this prospective randomized trial did not show superiority over cefazolin. Our findings therefore support two appropriate options for perioperative antibiotic prophylaxis in patients undergoing PCNL who are nonhigh risk for infectious complications.

Introduction and Objective: Holmium laser enucleation of the prostate (HoLEP) is often offered for symptomatic prostatic enlargement at high risk for bleeding. However, prior studies define clinically significant hematuria (CSH) narrowly as the need for blood transfusion or significant decrease in hemoglobin. We sought to evaluate risk factors contributing to a broader definition of CSH, which may contribute to alteration of clinical course. Methods: We analyzed 164 patients in a prospectively maintained database who underwent HoLEP at a single institution across two surgeons from November 2020 to April 2023. HoLEP was performed using Moses 2.0 (Boston Scientific) laser and the Piranha enucleation system (Richard Wolf). We defined CSH broadly as follows: clot retention, return to operating room, perioperative management variation due to hematuria, or continued gross hematuria past 1 month postoperatively. Univariable and multivariable ANOVAs were used. Multivariable analysis of CSH risk based on the use of antiplatelet (AP) agents or anticoagulants included correction for age, enucleation time (surrogate for case difficulty), and prostate volume. Results: 17.7% (29/164) of our patients developed CSH after HoLEP. Longer enucleation time was a mild risk factor for developing CSH (multivariate odds ratio [OR] 1.01, p = 0.02). The strongest predictor of CSH was the use of anticoagulation or AP agents (OR 2.71 p < 0.02 on univariable analysis, OR 2.34 p < 0.02 on multivariable analysis), even when aspirin 81 mg was excluded. Conclusion: With a broadened definition, 18% of patients developed CSH following HoLEP, which impacted the clinical course. Our data suggest that the current definition of significant hematuria is too narrow and does not capture many patients whose clinical course is affected by hematuria. While safe, anticoagulants and APs significantly predicted an increased CSH risk, and patients should be counseled accordingly.

Background: Inflammation has several effects in the geriatrics with reference to iron deficiency anemia (IDA), anemia of chronic disease (ACD), and unexplained anemia (UA). Whether hyperinflammation is part of their pathogenesis or just incidental is unknown. Data are limited regarding inflammatory patterns in IDA, ACD, and UA in anemic geriatrics and inflammation as a component of UA. There is little known about the overlap of inflammation between ACD and UA. Objective: The study was undertaken to find the proportion of anemic geriatric patients, aged ≥60 years with raised serum levels of inflammatory markers and their study within IDA, ACD, and UA. Materials and Methods: Seventy-five anemic geriatric patients were evaluated for raised serum levels of inflammatory markers: high sensitive C-reactive protein (hsCRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-8 (IL-8) along with serum ferritin (SF). Results: Raised markers were seen in 94.7% of anemic geriatric patients.IL-8 was raised most frequently followed by TNF-α, IL-6, hsCRP, and SF. No distinct inflammatory profile could be elicited between ACD and UA. The hyperinflammatory profile irrespective of the underlying etiology of geriatric anemia suggests that aging per se is pro-inflammatory state. Conclusion: Geriatric anemia can be thought to develop on background of subclinical low-grade inflammation along with superimposed nutritional deficiencies or chronic diseases.
RESUMO
Fluoroscopy is essential in percutaneous nephrolithotomy (PCNL) but exposes patients and operating room staff to radiation. We investigated whether a low-dose (LD) protocol could reduce radiation exposure during fluoroscopy-guided access without compromising clinical outcomes. Patients undergoing PCNL with fluoroscopy-guided access at a tertiary care stone center between January 2019 and July 2021 were identified. Prior to September 3, 2020, the Philips Veradius C-arm's default settings were used: standard per-frame dose, 15 pulses per second (PPS) frame rate. After this date, a low-dose protocol was used: reduced per-frame dose, reduced frame rate of 8 PPS for needle puncture and 4 PPS for all other steps. Clinical and radiographical data were retrospectively collected. The primary outcome was cumulative radiation dose. Secondary outcomes were stone-free status (SFS; defined as no fragments ≥ 2 mm) and complications. Multivariate regression analysis was performed. 100 patients were identified; 31 were in the LD group. The LD cohort was exposed to a significantly lower mean cumulative radiation dose of 11.68 mGy compared to 48.88 mGy (p < 0.0001). There were no differences in operative time, fluoroscopy time, stone burden, SFS, or complications. In a multivariable regression model adjusting for several variables, LD protocol was associated with lower radiation dose while skin-to-calyx-distance (STCD) was positively associated with cumulative radiation dose. Low-dose fluoroscopy and decreased frame rate during PCNL decreased radiation exposure fourfold without affecting SFS or complication rates.

Malignant tumors of sinonasal region are rare and affect less than 1 in 100,000 people per year. They are histologically diverse group and potentially pose significant management problems due to their proximity to the orbit and intracranial cavity. Although squamous cell carcinoma (SCC) is most common malignant tumor of paranasal cavity, tumors like adenocarcinoma, olfactory neuroblastoma, malignant melanoma, adenoid cystic carcinoma, sarcomas, haemoproliferative tumors, e.g. lymphoma may also occur. Retrospectively study was done in a tertiary care institute from January 2008 to December 2018 in India. Inclusion criteria-all biopsy proven PNS malignancy patients operated by endoscopic approach, irrespective of age and gender. Exclusion criteria- patients diagnosed with nasopharyngeal carcinoma, skin involvement, gross orbital involvement (muscle invasion), metastasis, operated by open approaches. 46 patients who underwent endoscopic tumor removal were reviewed. 36 (78.2%) were males and 10 (4.6%) females. Most common tumor in our study was adenoid cystic carcinoma. Recurrence was seen in 6 patients. Palliative therapy was given to all patients with recurrence. Management of malignant PNS tumor involving anterior skull base is multidisciplinary. R0 resection should be main goal in all malignant PNS malignancy. Tumors invading unresectable areas like cavernous sinus, brain parenchyma, carotids can be left in these places followed by palliation except in cases of squamous cell carcinoma. If R0 cannot be achieved surgically in SCC than patient should be considered inoperable and send for palliation. T1-T3 PNS malignant tumors can be managed by endoscopic approach followed by adjuvant therapy after a period of 6 weeks. Endoscopic excision should be converted to endoscopic assisted open approach in case of T4 tumors. We have tried to give a management protocol for management of malignant PNS tumors. Level of evidence: II.
RESUMO
Objective This study was aimed to understand the usefulness of transarterial angiography and embolization in management of juvenile nasopharyngeal angiofibroma (JNA) and to apply the information obtained to stage the disease, select appropriate surgical approach, predict intraoperative bleeding, and prognosticate the disease. Study Design This study represents a retrospective review of the patients of JNA with major focus on transarterial angiography and embolization findings and its clinical and surgical implications. Setting The study conducted at a tertiary-care super-specialty referral center. Participants Forty-two patients who had undergone transarterial angiography and embolization followed by surgery over the period of 5 years from July 2015 till February 2019 were participated in this study. Main Outcome Measures Tumor vascular pattern based on transarterial angiography, staging of the disease based on extent and vascular supply, surgical approach selected, and prognosticating the disease were determined from this study. Conclusion Transarterial angiography with embolization becomes a prudent preoperative investigation for management of JNA. It provides a complete three-dimensional map of the tumor with stage-specific vascular pattern, reduces vascularity of the tumor, and predicts the sites from where bleeding can occur intra operatively. Thus, it helps in choosing the appropriate surgical approach aiding in complete tumor removal with minimal bleeding.
RESUMO
PURPOSE: Pain is the leading cause of unplanned emergency department visits and readmissions after ureteroscopy, making postoperative analgesic stewardship a priority given the current opioid epidemic. We conducted a double-blinded, randomized controlled trial, with noninferiority design, comparing nonsteroidal anti-inflammatory drugs to opiates for postoperative pain control in patients undergoing ureteroscopy for urolithiasis. MATERIALS AND METHODS: Patients were randomized and blinded to either oxycodone (5 mg) or ketorolac (10 mg), taken as needed, with 3 nonblinded oxycodone rescue pills for breakthrough pain. Primary study outcome was visual analogue scale pain score on postoperative days 1-5. Secondary outcomes included medication utilization, side effects, and Ureteral Stent Symptom Questionnaire scores. RESULTS: A total of 81 patients were included (43 oxycodone, 38 ketorolac). The 2 groups had comparable patient, stone, and perioperative characteristics. No differences were found in postoperative pain scores, study medication or rescue pill usage, or side effects. Higher maximum pain scores on days 1-5 (p <0.05) and higher questionnaire score (28.1 vs 21.7, p=0.045) correlated with analgesic usage, irrespective of treatment group. Patients receiving ketorolac reported significantly fewer days confined to bed (mean±SD 1.3±1.3 vs 2.3±2.6, p=0.02). There was no difference in unscheduled postoperative physician encounters. CONCLUSIONS: This is the first double-blinded randomized controlled trial comparing nonsteroidal anti-inflammatory drugs and opiates post-ureteroscopy, and demonstrates noninferiority of nonsteroidal anti-inflammatory drugs in pain control with similar efficacy, safety profile, physician contact and notably, earlier convalescence compared to the opioid group. This provides strong evidence against routine opioid use post-ureteroscopy, justifying continued investigation into reducing postoperative opiate prescriptions.

INTRODUCTION: This study sought to characterize delays and estimate resulting costs during nephrolithiasis surgery. METHODS: Independent observers documented delays during ureteroscopy (URS) and percutaneous nephrolithotomy (PCNL) procedures. Fifty index cases over a period of three months was considered sufficient to observe the generalizable trends. Operating room staff, excluding the surgeons, were blinded. Time-related metrics and delays preventing case progression were recorded using a smartphone-accessible data-collection instrument. Delays were categorized as: 1) missing equipment; 2) missing personnel; 3) equipment malfunction; or 4) delay due to case complexity. The first two categories were regarded as preventable and the latter two non-preventable. RESULTS: Forty URS and 18 PCNL cases were included. There was a total of 56 delays in 35 (65%) cases. Twelve (67%) PCNLs and 23 (58%) URSs had delays (p=0.57). The mean cumulative delay per case was 3.5±3.2 minutes. Pre-start delays (n=17) were 4.5±3.5 minutes on average while intraoperative delays (n=39) were 3.1±2.9 minutes (p=0.167). Delays were evenly spread among the four categories. Thirty-one (55%) delays were preventable (mean 3.7±3.2 minutes) while 25 (45%) were non-preventable (mean 3.2±3.2 minutes) (p=0.58). This translates to $137 per case in preventable costs. CONCLUSIONS: Preventable operative delays are encountered frequently in nephrolithiasis surgery, translating to significant additional charges and costs. We demonstrate a rationale for the development of improved communication and workflow protocols to increase efficiency in endourological surgeries. Key limitations are the observational nature of the study and sample size.
RESUMO
Main limitation of classical technique is limited access to cochlea in terms of cochlear rotations and related structures, thus causing difficulty in electrode insertion. Veria technique allows full access to cochlea after raising tympanomeatal flap. To our best knowledge this is first clinic-radiological study for Veria technique studying distance between tympanic segment of facial nerve and posterior wall of external auditory canal (EAC) demonstrating facial nerve safety. Prospective study was done on 50 patients having bilateral sensori-neural hearing loss. Patients underwent cochlear implant surgery irrespective of age and gender. Preoperative high-resolution computed tomography temporal bone and magnetic resonance imaging head was done, distance between tympanic segment of facial nerve and posterior wall of EAC and basal turn angle were measured. Intraoperative NRT followed by orbito-meatal X-ray was done in post operative period. 25 (50%) were male, 25 (50%) female. 35 patients (70%) showed that the distance between tympanic segment of facial nerve and posterior wall of EAC was more than 3 mm with mean 4.41 mm (± 0.63 SD). Distance calculated was greater in older age group than younger group. Patient having inner ear malformation, mean was 3.96 mm (± .44 SD). Whereas patients having acquired disease, mean distance was 4.30 mm (± .47 SD). On gender comparison of basal turn angle score, no significant difference was observed male (54.34° ± 4.48°) versus female (55.66° ± 4.15°) (p = 0.282). Mean of basal turn angle (BTA) in ≤ 5 years age group was 54.89° ± 3.65°, in 6-10 years age group was 55.21° ± 5.23° and in age group ≥ 11 years was 54.93° ± 4° with no significant difference in mean value between the groups (p = 0.282). High jugular bulb was seen in 4 patients (2 in right side, 2 in left side), hypoplastic jugular bulb was seen in 10 patients (9 in left, 1 in right), otosclerosis in 2 patients. Veria technique is safe for facial nerve, as preoperatively distance between tympanic segment of facial nerve and posterior canal wall can be identified. It is suitable method for rotated cochlea (identified preoperatively through BTA) and deformed cochlea as it offers a wide visibility and accessibility as compared to posterior tympanotomy approach. BTA and distance between posterior canal wall of EAC and tympanic segment of facial nerve should be done in all cases to see any cochlear rotation and feasibility of surgery.
RESUMO
Introduction Cerebrospinal fluid (CSF) rhinorrhea is the leakage of CSF through nasal cavity, due to abnormal communication between the arachnoid membrane and nasal mucosa. Middle-age (fourth to fifth decade) group, female gender, and obesity (body mass index > 40) are the most commonly reported risk-factors for this rare entity. In this study, we present our single center experience of spontaneous CSF rhinorrhea discussing important clinicoradiological aspects in preoperative evaluation and nuances in the endoscopic repair technique. Material and Methods A retrospective study conducted for 43 spontaneous CSF rhinorrhea patients admitted between Jan 2011 to Jan 2018 at our tertiary care center. All patients underwent endoscopic repair of the defect depending upon their site of leak. Results Mean age in our study was 36.7 ± 12.3 years (range: 9-62 years). Average BMI in males was found lower (28.7) as compared with females (32). Most common site of CSF leak was cribriform plate ( n = 32, 74.4%) and Planum was found to be the least common site ( n = 1, 2.3%) of CSF leak. Intraoperatively, 23 (53.5%) patients showed high-flow leak. Intrathecal injection of fluorescein dye was used to identify the site of CSF leakage in 15 cases (34.8%). The overall success rate of primary endoscopic repair in our study was 95.3%. Conclusion Spontaneous CSF rhinorrhea occurs secondary to elevated intracranial pressure, with a predilection for obese females in fourth to fifth decade. Individualized tailored surgical approach depending upon the site, size, and flow-variety of the defect forms the cornerstone of management.
RESUMO
OBJECTIVE: To develop a contemporary complication profile for supracostal upper pole endoscopic-guided prone tubeless "maxi-PCNL" to evaluate the need for change. MATERIALS/METHODS: We identified patients undergoing supracostal upper pole percutaneous nephrolithotomy (PCNL) by a single surgeon at a high volume tertiary care stone center between October 2010 and April 2017. Access was obtained with ureteroscopic guidance. The tract was dilated to 30F through radial balloon dilation. All cases were tubeless with ureteral stent for 5-7 days. Preoperative, operative, and postoperative variables were recorded. We recorded need for blood transfusion, angioembolization, thoracentesis and/or chest tube insertion, intensive care unit (ICU) admission, and 30-day readmission. RESULTS: A total of 375 patients were included. Mean age was 57 years and 59% were women. Mean body mass index was 33 kg/m2. Mean stone burden was 35 mm. The mean operative time was 99 minutes. Median stay was 1 day. There were no complications because of prone position. Postoperative complications included pleural drain (4%), transfusion (6.7%), and angioembolization (0.5%). Transfusion rates were higher in patients with preoperative hemoglobin <10 mg/dL (28% vs 5.1%, p < 0.00001). Rate of ICU admission and readmission was 4.5% and 7.5%, respectively. Transfusion (p ≤ 0.001), pleural drain (p = 0.0002), and readmission (p = 0.030) were associated with ICU admission. Male gender was associated with readmission (10.3% vs 5.5%, odds ratio = 3.1, p = 0.012). CONCLUSIONS: In supracostal upper pole endoscopic-guided prone tubeless Maxi-PCNL, pulmonary complication rate was lower than previously reported and bleeding complications were comparable with mini-PCNL series. Establishing contemporary complication rates will help to assess the need for evolution to mini-PCNL or lower pole supine PCNL.

INTRODUCTION: Ureteral duplication is the most common ureteral anomaly, occurring in 0.6%-0.7% of the population. Our objective was to compare urolithiasis treatment outcomes in patients with and without ureteral duplication. METHODS: Patients with ureteral duplication who underwent ureteroscopy (URS) were identified in a stone registry at a high-volume, tertiary care center from 1998 to 2015. Preoperative, intraoperative, and postoperative data were collected retrospectively. A 1:1 control cohort of patients without duplication was identified, matched by stone location and size, as well as age, body mass index (BMI), and gender. Clinical data and outcomes were compared between duplication and control groups, between partial and complete duplication groups, and between patients in whom duplication was identified intraoperatively vs known preoperatively. RESULTS: Fifty patients with ureteral duplication who underwent URS were identified and were matched to 50 control patients. Patients with ureteral duplication required longer operative time (55 minutes vs 38.5 minutes, p = 0.022). Ureteral duplication had no effect on stone-free rates or need for additional procedures. High-grade (Clavien 4-5) complications were similar in both groups (4% vs 4%). Location of ureteral duplication and preoperative knowledge of ureteral duplication did not affect operative time or stone-free rates. CONCLUSIONS: Patients with ureteral duplication undergoing URS for urinary stone disease have longer operative times. Preoperative knowledge of ureteral duplication appears to have no significant effect on URS's safety or efficacy. In patients without a prior diagnosis of ureteral duplication, our data suggest that intraoperative detection via endoscopy and fluoroscopy is sufficient to safely and completely treat stone disease.

PURPOSE: To study the outcome of therapeutic keratoplasty in severe microbial keratitis cases otherwise advised evisceration. METHODS: A retrospective, single-center clinical audit included 28 patients with severe microbial keratitis presenting from April 2014 to April 2016. Patients with microbial keratitis either affecting more than 2 quadrants of the limbus and/or cases with infections involving more than 180 mm of the cornea who were advised evisceration by more than one ophthalmologist were included. Cases with endophthalmitis were excluded. At 3 months, the outcome was "success" if resolution of infection occurred without recurrence and evisceration was not required. Success was termed "complete" if best vision was 6/24 or better and "partial" otherwise. The outcome was termed a "failure" if infection recurred in the graft or the eye was eviscerated. RESULTS: Mean age of the patients (male:female, 17:11) was 49.5 years, and the mean duration of symptoms before surgery was 28.6 days. Evisceration was required in 2/28 cases. The outcome was "success" in 22/28 cases (78.6%)-complete (10/22); partial (12/22)-and "failure" in 6/28 cases. The outcome was poorer in general in fungal keratitis (n = 16) than bacterial keratitis (n = 7). CONCLUSIONS: Primary evisceration is best avoided in infections limited to the anterior segment. Even in hopeless cases, every eye deserves a fair chance.

OBJECTIVE: To compare stone composition and serum/urine biochemistries in stone formers with multiple sclerosis (MS) against stone formers without MS and to examine the association between mobility, methods of bladder emptying, and stone formation. PATIENTS AND METHODS: In this retrospective case-control study, we identified patients diagnosed with MS and kidney stone disease who were seen at our institution between 2001 and 2016. For the first part of the study, up to two controls (stone formers without a history of MS) were identified for each case and matched on age, body mass index, and sex. For the second part of this study, matched controls (MS patients without a history of stones) were identified in a 1:1 ratio in a similar fashion. Results of 24-h urine biochemistry studies, stone compositions, serum laboratory measures, medications, history of stone surgeries, mobility, and method of bladder emptying were collected. RESULTS: In all, 587 patients were identified who had both MS and a history of stone disease. Of these, 118 patients had a stone composition available. When compared to matched controls, patients with MS were significantly more likely to have calcium phosphate stones (42% vs 15%, P < 0.001) and struvite stones (8% vs 3%, P = 0.03) and less likely to have calcium oxalate monohydrate stones (39% vs 64%, P < 0.001). Among those patients with a composition available, those with MS were more likely to have undergone a percutaneous nephrolithotomy (PCNL; 25% vs 12%, P = 0.005) or a cystolithopaxy (16% vs 3%, P < 0.001) compared to their matched controls. In all, 61 patients had a complete 24-h urinary stone panel. There were no significant differences in urinary pH, volume, creatinine, calcium, citrate, oxalate, sodium, and uric acid as well as rates of hypocitraturia, hyperoxaluria, hypercalciuria, and hyperuricosuria among patients with MS. Use of intermittent straight catheterisation [ISC; odds ratio (OR) 3.50, 95% confidence interval (CI) 1.89-6.47]; P < 0.001] or an indwelling catheter (OR 9.78, 95% CI 4.81-19.88; P < 0.001) for bladder emptying was significantly associated with stone disease. There was no association between level of mobility and stone disease (P = 0.10). CONCLUSIONS: Similar to findings seen in patients with spinal cord injuries, patients with MS have a high incidence of calcium phosphate stones and struvite stones when compared with matched controls. Additionally, they were more likely to undergo PCNL. The method of bladder management appears to be a risk factor in the development of stone disease. These findings suggest the importance of prompt treatment of urinary tract infections in this population and delay the use of ISC, suprapubic tube, or an indwelling Foley, when possible.
