ABSTRACT

Objectives: To determine the utility of ultrasonography (US)-derived parameters (e.g. prostate volume [PV], bladder wall thickness [BWT], post-void residual urine volume [PVR], and intravesical prostatic protrusion [IPP]) and uroflowmetry for identifying bladder outlet obstruction (BOO) by correlating them with the results of pressure-flow urodynamic studies (UDS). Patients and methods: In all, 164 patients presenting with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH), from May 2016 to December 2018, were included in this study. All had International Prostate Symptoms Score (IPSS), Quality-of-Life (QOL) index, uroflowmetry (including maximum urinary flow rate [Qmax]) and PVR measured by transabdominal US. Pressure-flow UDS were performed on all men and BOO was defined by a BOO Index (BOOI) >40. Men with a Qmax of ≥12.0 mL/s were considered to have 'good' flow. Results: Amongst the 164 men, the mean (SD) age, PV, BWT and Qmax were 66.72 (9.88) years, 51.91 (13.24) mm, 5.07 (0.91) mm, and 8.46 (3.59) mL/s, respectively. In all, 91 (55.49%) patients had BOO with a BOOI >40 and nine (5.49%) had equivocal BOO with a BOOI of 20-40. The IPP was a statistically significant predictor (P < 0.001) of BOO compared with other variables in the initial evaluation. In patients with BOO confirmed by the pressure-flow UDS, IPP Grade III was associated with a higher BOOI than was Grade I and II (P < 0.001). Conclusion: BWT, PV and PVR in conjunction with IPP are good predictors of clinically significant BOO due to BPH. Abbreviations: AUC: area under the curve; BOOI: BOO Index; BPO, benign prostatic obstruction; BWT, bladder wall thickness; IPP: intravesical prostatic protrusion; Pdet: detrusor pressure; PV: prostate volume; PVR: post-void residual urine volume; Qmax: maximum urinary flow rate; QOL: quality of life; ROC: receiver operating characteristic; (TA)US: (transabdominal) ultrasonography; UDS: urodynamic studies.

ABSTRACT

PURPOSE: To compare the efficacy of percutaneous nephrolithotomy (PCNL) as a primary procedure of patients following previous open surgery or post percutaneous nephrolithotomy (PCNL) for renal calculi. MATERIALS AND METHODS: The medical records of 367 patients who underwent PCNL by a single surgeon from January 2008 to December 2013 were reviewed retrospectively. All patients were divided into 3 Groups. Group-1 (n=232) included patients with no history of ipsilateral open stone surgery. Group 2 (n=86) patients had undergone one or more open stone surgeries before PCNL, patients with failed or recurrence following PCNL were placed in Group-3 (n=49). The demographic data, operation duration, stone free rate (SFR), number of attempts to access the collecting system and intra operative and postoperative complications between the three Groups were compared. RESULTS: There was no difference in sex, Body Mass Index (BMI), stone burden and laterality among the three Groups. Operation time was significantly less in first Group, while there was a statistically significant difference in operation duration between second and third Groups (p<0.05). The number of attempts to enter the collecting system was lower in the first Group in comparison to other two Groups (p<0.5). There was no significant differences among three groups in stone free rate. Intra operative and postoperative complications were slightly more frequent in Groups 2 and 3. Mortality occurred in 1 patient with colon perforation in Group-2. CONCLUSION: Our study demonstrated that PCNL can be performed in patients even as secondary procedure without further complications.

ABSTRACT

PURPOSE: To study the effects of long-term treatment with potassium magnesium citrate and vitamin B-6 prophylaxis (Urikind-KM6; 1,100-mg potassium citrate, 375-mg magnesium citrate, and 20-mg pyridoxine hydrochloride/5 mL) every 8 hours over 3 years. MATERIALS AND METHODS: A total of 247 patients with recurrent idiopathic hypocitraturia with or without hyperuricosuria and randomized controls were studied prospectively for 3 years. The total patients were divided into three groups. Control group 1 consisted of 61 patients (24.7%) who had moderate to severe hypocitraturia with or without hyperuricosuria and were recurrent stone formers but discontinued prophylaxis because of drug intolerance within 1 month of therapy. Control group 2 constituted 53 patients (21.5%) who were first-time stone formers and who had mild hypocitraturia with or without hyperuricosuria and were not put on prophylactic therapy and were followed for 3.16±0.08 years. Control group 3 constituted 133 patients (54.8%) who were recurrent stone formers who had moderate to severe hypocitraturia with or without hyperuricosuria and were put on prophylaxis therapy and were followed for 3.16±0.08 years. All patients were followed up at 6-month intervals. RESULTS: Potassium magnesium citrate prophylaxis produced a sustained increase in 24-hour urinary citrate excretion from initially low values (221.79±13.39 mg/dL) to within normal to high limits (604.04±5.00 mg/dL) at the 6-month follow-up. Urinary pH rose significantly from 5.62±0.2 to 6.87±0.01 and was maintained at 6.87±0.01. The stone recurrence rate declined from 3.23±1.04 per patient per year to 0.35±0.47 per patient per year. CONCLUSIONS: Potassium magnesium citrate prophylaxis was effective in reducing the recurrence of calcium oxalate and phosphate urolithiasis.

ABSTRACT

Various self-inflicted foreign bodies have been removed from the lower urinary tract and external male genitalia. In many cases foreign bodies were inserted or applied for autoerotic reasons which are frequently associated with mental health disorders. Here the author reports an unusual case of self insertion of a 6-cm long metal needle at penoscrotal junction of the erect penis for sexual pleasure. The stitching needle was inserted by a 20-year old male who was too ashamed to admit the motive at first. The caudal end of the needle was palpable at the root of the penis as it was below the urogenital diaphragm. The needle was successfully removed under fluoroscopic guidance with minor surgical exploration and with no complications.
