Abstract

Purpose: There are limited data on ablation effects of thulium fiber laser (TFL) settings with varying stone composition. Similarly, little is known surrounding the photothermal effects of TFL lithotripsy regarding the chemical and structural changes after visible char formation. We aim to understand the TFL's ablative efficiency across various stone types and laser settings, while simultaneously investigating the photothermal effects of TFL lithotripsy. Materials and Methods: Human specimens of calcium oxalate monohydrate, calcium oxalate dihydrate, uric acid, struvite, cystine, carbonate apatite, and brushite stones were ablated using 13 prespecified settings with the Coloplast TFL Drive. Pre- and postablation mass, ablation time, and total energy were recorded. Qualitative ablative observations were recorded at 1-minute intervals with photographs and gross description. Samples were analyzed with Fouriertransform infrared spectroscopy pre- and postablation and electron microscopy postablation to assess the photothermal effects of TFL. Results: Across all settings and stone types, 0.05 J ≥ 1000 Hz was the best numerically efficient ablation setting. When selected for more clinically relevant laser settings (ie, 10-20 W), 0.2 J =≥100 Hz, short pulse was the most numerically efficient setting for calcium oxalate dihydrate, cystine, and struvite stones. Calcium oxalate monohydrate ablated with the best numerical efficiency at 0.4 J ≥ 40 Hz, short pulse. Uric acid and carbonate apatite stones ablated with the best numerical efficiency at 0.3 J ≥ 60 Hz, short pulse. Brushite stones ablated with the best numerical efficiency at 0.5 J ≥ 30 Hz, short pulse. Pulse duration impacted ablation effectiveness greatly with 6/8 (75%) of inadequate ablations occurring in medium or long pulse settings. The average percent of mass lost during ablation was 57%; cystine stones averaged the highest percent mass lost at 71%. Charring was observed in 36/91 (40%) specimens. Charring was most often seen in uric acid, cystine, and brushite stones across all laser settings. Electron microscopy of char demonstrated a porous melting effect different to that of brittle fracture. Fourier-transform infrared spectroscopy of brushite char demonstrated a chemical composition change to amorphous calcium phosphate. Conclusions: We describe the optimal ablation settings based on stone composition, which may guide urologists towards more stone-specific care when using thulium laser for treating renal stones (lower energy settings would be safer for ureteral stones). For patients with unknown stone composition, lasers can be preset to target common stone types or adjusted based on visual cues. We recommend using short pulse for all TFL lithotripsy of calculi and altering the settings based on visual cues and efficiency to minimize the charring, an effect which can make the stone refractory to further dusting and fragmentation.

Abstract

The article describes the case of a 54-year-old Hispanic man with bladder cancer and concomitant IgG4-mediated GU disease causing intermittent gross haematuria. Highlights include diffusely thickened bladder wall shown by preoperative imaging, urine cytology collected from the neobladder, and repeat pathological evaluation of the patient's cystectomy specimen.

43. Rare case of an isolated scaphoid congenital megalourethra: before and after reconstruction.

Abstract

Congenital megalourethra, first described in 1955, is a rare urethral anomaly resulting from dysgenesis of the penile corpus spongiosum, with or without corpus cavernosum involvement, leading to dilatation of the penile urethra. Presentations come in two forms, scaphoid and fusiform, with the former being more common and resulting from deficient or absent corpus spongiosum. Fusiform types are much rarer, and consist of absence of both the corpus spongiosum and cavernosum.3 Here, we present a case involving the surgical correction of an isolated scaphoid-type congenital megalourethra with significantly improved postoperative cosmetic and functional outcomes.
